social responsibility 2

What Is Social Responsibility? Being Socially Responsible means that people and organisations must behave ethically and with sensitivity toward social, cultural, economic and environmental issues. Striving for social responsibility helps individuals, organisations and governments have a positive impact on development, business and society with a positive contribution to bottom-line results. Individual Social Responsibility (ISR) to achieve Corporate Social Responsibility (CSP) ISP may appear to be a new concept in relation to CSP, but it is a concept as old as The Golden Rule — Do unto others as you would have them do unto you. ISR expands on this by promoting a proactive stance towards positively influencing and affecting the people and environments outside your immediate circle. ISR is at the roots of CSR, because a corporate comprises of individuals and hence determines the social responsibility culture it creates. This is the intermingled relationship between CSR and ISR. Individuals are becoming more socially responsible and, in response to this Corporations and Companies need to become more socially responsible to meet consumer demand. The International Organisation for Standardisation (ISO) states: “In the wake of increasing globalisation, we have become increasingly conscious not only of what we buy, but also how the goods and services we buy have been produced. Environmentally harmful production, child labor, dangerous working environments and other inhumane conditions are examples of issues being brought into the open. All companies and organisations aiming at long-term profitability and credibility are starting to realise that they must act in accordance with norms of right and wrong.” Socially responsible individuals are demanding companies and organisations to become more socially responsible. How Does an Individual Become Socially Responsible? The Workshop for Civic Initiatives Foundation (WCIF), Bulgaria, describes ISR in its position statement on Social Responsibility as, “The individual social responsibility includes the engagement of each person towards the community where he lives, which can be expressed as an interest towards what’s happening in the community, as well as in the active participation in the solving of some of the local problems. Under community we understand the village, the small town or the residential complex in the big city, where lives every one of us. Each community lives its own life that undergoes a process of development all the time. And everyone of us could take part in that development in different ways, for example by taking part in cleaning of the street on which he lives, by taking part in organization of an event, connected with the history of the town or the village or by rendering social services to children without parents or elderly people. The individual social responsibility also could be expressed in making donations for significant for the society causes – social, cultural or ecological. There are many ways of donating, as for example donating of goods or donating money through a bank account or online” Social Responsibility can be “negative,” in that it is a responsibility to refrain from acting (resistance stance) or it can be “positive,” meaning there is a responsibility to act (proactive stance). Being socially responsible not only requires participating in socially responsible activities like recycling, volunteering and mentoring, but to actually make it a lifestyle. Only through a commitment to embrace and embed social responsibility into your personal value and belief system can you truly become socially responsible in all you do. According to The Harris Poll ®#57 , June 18, 2007[7], when it comes to individual social responsibility, there are three types of people: 1. Two-thirds of U.S. adults have “Good Intentions” – they believe that social responsibility is a good idea, and they do what they can in terms of volunteering, but they do not sacrifice huge amounts of time or money. 2. At the top end of the spectrum, 8 percent of U.S. adults “Practice What They Preach” and for this group, individual, as well as corporate, social responsibility is extremely important. 3. One-quarter of U.S. adults, however, follow a philosophy of “To Thine Own Self Be True” and, for this group, social responsibility has little consequence in their lives. On the other hand the trends show that the biggest growth for big charitable organisations in the world is coming through individuals and not through Corporations and Governments [8]. To take a proactive stance, ISR can start off as a simple act of philanthropic behaviour. My husband and I actually budget for giving, just like we do for living or car expenses. Add to this the campaigner, volunteer and activist in you that picks-up and supports issues affecting society. You may just start off volunteering once a month somewhere that suits your skills, abilities or interests. The other day, I asked a friend if he could teach my son guitar. We determined a tuition cost but instead of me paying him, he asked me if I could pay the charity of his choice. If you have the choice of two products and one product supports a good cause or was produced in a more ethical way, then purchase that product. You may only be one person but if everyone did their part, we could change the world! All Social responsibility, both individual and corporate, is voluntary; it is about going above and beyond what is called for by the law(legal responsibility). It involves an idea that it is better to be proactive toward a problem rather than reactive to a problem. Social responsibility means eliminating corrupt, irresponsible or unethical behavior that might bring harm to the community, its people, or the environment before the behavior happens. CORPORATE/BUSINESS SOCIAL RESPONSIBILITY Corporate social responsibility (CSR) can be defined as the "economic, legal, ethical, and discretionary expectations that society has of organizations at a given point in time" (Carroll and Buchholtz 2003, p. 36). The concept of corporate social responsibility means that organizations have moral, ethical, and philanthropic responsibilities in addition to their responsibilities to earn a fair return for investors and comply with the law. A traditional view of the corporation suggests that its primary, if not sole, responsibility is to its owners, or stockholders. However, CSR requires organizations to adopt a broader view of its responsibilities that includes not only stockholders, but many other constituencies as well, including employees, suppliers, customers, the local community, local, state, and federal governments, environmental groups, and other special interest groups. Collectively, the various groups affected by the actions of an organization are called "stakeholders." The stakeholder concept is discussed more fully in a later section. Corporate social responsibility is related to, but not identical with, business ethics. While CSR encompasses the economic, legal, ethical, and discretionary responsibilities of organizations, business ethics usually focuses on the moral judgments and behavior of individuals and groups within organizations. Thus, the study of business ethics may be regarded as a component of the larger study of corporate social responsibility. Carroll and Buchholtz's four-part definition of CSR makes explicit the multi-faceted nature of social responsibility. The economic responsibilities cited in the definition refer to society's expectation that organizations will produce good and services that are needed and desired by customers and sell those goods and services at a reasonable price. Organizations are expected to be efficient, profitable, and to keep shareholder interests in mind. The legal responsibilities relate to the expectation that organizations will comply with the laws set down by society to govern competition in the marketplace. Organizations have thousands of legal responsibilities governing almost every aspect of their operations, including consumer and product laws, environmental laws, and employment laws. The ethical responsibilities concern societal expectations that go beyond the law, such as the expectation that organizations will conduct their affairs in a fair and just way. This means that organizations are expected to do more than just comply with the law, but also make proactive efforts to anticipate and meet the norms of society even if those norms are not formally enacted in law. Finally, the discretionary responsibilities of corporations refer to society's expectation that organizations be good citizens. This may involve such things as philanthropic support of programs benefiting a community or the nation. It may also involve donating employee expertise and time to worthy causes. HISTORY The nature and scope of corporate social responsibility has changed over time. The concept of CSR is a relatively new one—the phrase has only been in wide use since the 1960s. But, while the economic, legal, ethical, and discretionary expectations placed on organizations may differ, it is probably accurate to say that all societies at all points in time have had some degree of expectation that organizations would act responsibly, by some definition. In the eighteenth century the great economist and philosopher Adam Smith expressed the traditional or classical economic model of business. In essence, this model suggested that the needs and desires of society could best be met by the unfettered interaction of individuals and organizations in the marketplace. By acting in a self-interested manner, individuals would produce and deliver the goods and services that would earn them a profit, but also meet the needs of others. The viewpoint expressed by Adam Smith over 200 years ago still forms the basis for free-market economies in the twenty-first century. However, even Smith recognized that the free market did not always perform perfectly and he stated that marketplace participants must act honestly and justly toward each other if the ideals of the free market are to be achieved. In the century after Adam Smith, the Industrial Revolution contributed to radical change, especially in Europe and the United States. Many of the principles espoused by Smith were borne out as the introduction of new technologies allowed for more efficient production of goods and services. Millions of people obtained jobs that paid more than they had ever made before and the standard of living greatly improved. Large organizations developed and acquired great power, and their founders and owners became some of the richest and most powerful men in the world. In the late nineteenth century many of these individuals believed in and practiced a philosophy that came to be called "Social Darwinism," which, in simple form, is the idea that the principles of natural selection and survival of the fittest are applicable to business and social policy. This type of philosophy justified cutthroat, even brutal, competitive strategies and did not allow for much concern about the impact of the successful corporation on employees, the community, or the larger society. Thus, although many of the great tycoons of the late nineteenth century were among the greatest philanthropists of all time, their giving was done as individuals, not as representatives of their companies. Indeed, at the same time that many of them were giving away millions of dollars of their own money, the companies that made them rich were practicing business methods that, by today's standards at least, were exploitative of workers. Around the beginning of the twentieth century a backlash against the large corporations began to gain momentum. Big business was criticized as being too powerful and for practicing antisocial and anticompetitive practices. Laws and regulations, such as the Sherman Antitrust Act, were enacted to rein in the large corporations and to protect employees, consumers, and society at large. An associated movement, sometimes called the "social gospel," advocated greater attention to the working class and the poor. The labor movement also called for greater social responsiveness on the part of business. Between 1900 and 1960 the business world gradually began to accept additional responsibilities other than making a profit and obeying the law. In the 1960s and 1970s the civil rights movement, consumerism, and environmentalism affected society's expectations of business. Based on the general idea that those with great power have great responsibility, many called for the business world to be more proactive in (1) ceasing to cause societal problems and (2) starting to participate in solving societal problems. Many legal mandates were placed on business related to equal employment opportunity, product safety, worker safety, and the environment. Furthermore, society began to expect business to voluntarily participate in solving societal problems whether they had caused the problems or not. This was based on the view that corporations should go beyond their economic and legal responsibilities and accept responsibilities related to the betterment of society. This view of corporate social responsibility is the prevailing view in much of the world today. The sections that follow provide additional details related to the corporate social responsibility construct. First, arguments for and against the CSR concept are reviewed. Then, the stakeholder concept, which is central to the CSR construct, is discussed. Finally, several of the major social issues with which organizations must deal are reviewed. ARGUMENTS FOR AND AGAINST CORPORATE SOCIAL RESPONSIBILITY The major arguments for and against corporate social responsibility are shown in Exhibit 1. The "economic" argument against CSR is perhaps most closely associated with the American economist Milton Friedman, who has argued that the primary responsibility of business is to make a profit for its owners, albeit while complying with the law. According to this view, the self-interested actions of millions of participants in free markets will, from a utilitarian perspective, lead to positive outcomes for society. If the operation of the free market cannot solve a social problem, it becomes the responsibility of government, not business, to address the issue. FOR AGAINST The rise of the modern corporation created and continues to create many social problems. Therefore, the corporate world should assume responsibility for addressing these problems. Taking on social and moral issues is not economically feasible. Corporations should focus on earning a profit for their shareholders and leave social issues to others. In the long run, it is in corporations' best interest to assume social responsibilities. It will increase the chances that they will have a future and reduce the chances of increased governmental regulation. Assuming social responsibilities places those corporations doing so at a competitive disadvantage relative to those who do not. Large corporations have huge reserves of human and financial capital. They should devote at least some of their resources to addressing social issues. Those who are most capable should address social issues. Those in the corporate world are not equipped to deal with social problems. The "competitive" argument recognizes the fact that addressing social issues comes at a cost to business. To the extent that businesses internalize the costs of socially responsible actions, they hurt their competitive position relative to other businesses. This argument is particularly relevant in a globally competitive environment if businesses in one country expend assets to address social issues, but those in another country do not. According to Carroll and Buchholtz, since CSR is increasingly becoming a global concern, the differences in societal expectations around the world can be expected to lessen in the coming years. Finally, some argue that those in business are ill-equipped to address social problems. This "capability" argument suggests that business executives and managers are typically well trained in the ways of finance, marketing, and operations management, but not well versed in dealing with complex societal problems. Thus, they do not have the knowledge or skills needed to deal with social issues. This view suggests that corporate involvement in social issues may actually make the situation worse. Part of the capability argument also suggests that corporations can best serve societal interests by sticking to what they do best, which is providing quality goods and services and selling them at an affordable price to people who desire them. There are several arguments in favor of corporate social responsibility. One view, held by critics of the corporate world, is that since large corporations create many social problems, they should attempt to address and solve them. Those holding this view criticize the production, marketing, accounting, and environmental practices of corporations. They suggest that corporations can do a better job of producing quality, safe products, and in conducting their operations in an open and honest manner. A very different argument in favor of corporate social responsibility is the "self-interest" argument. This is a long-term perspective that suggests corporations should conduct themselves in such a way in the present as to assure themselves of a favorable operating environment in the future. This view holds that companies must look beyond the short-term, bottom-line perspective and realize that investments in society today will reap them benefits in the future. Furthermore, it may be in the corporate world's best interests to engage in socially responsive activities because, by doing so, the corporate world may forestall governmental intervention in the form of new legislation and regulation, according to Carroll and Buchholtz. Finally, some suggest that businesses should assume social responsibilities because they are among the few private entities that have the resources to do so. The corporate world has some of the brightest minds in the world, and it possesses tremendous financial resources. (Wal-Mart, for example, has annual revenues that exceed the annual GNP of some countries.) Thus, businesses should utilize some of their human and financial capital in order to "make the world a better place." THE STAKEHOLDER CONCEPT According to Post, Lawrence, and Weber, stakeholders are individuals and groups that are affected by an organization's policies, procedures, and actions. A "stake" implies that one has an interest or share in the organization and its operations, per Carroll and Buchholtz. Some stakeholders, such as employees and owners, may have specific legal rights and expectations in regard to the organization's operations. Other stakeholders may not have specific rights granted by law, but may perceive that they have moral rights related to the organization's operations. For example, an environmental group may not have a legal right in regard to a company's use of natural resources, but may believe that they have a moral right to question the firm's environmental policies and to lobby the organization to develop environmentally friendly policies. All companies, especially large corporations, have multiple stakeholders. One way of classifying stakeholder groups is to classify them as primary or secondary stakeholders. Primary stakeholders have some direct interest or stake in the organization. Secondary stakeholders, in contrast, are public or special interest groups that do not have a direct stake in the organization but are still affected by its operations. Exhibit 2 classifies some major stakeholder groups into primary and secondary categories. The owners of a firm are among the primary stakeholders of the firm. An organization has legal and moral obligations to its owners. These obligations include, but are not limited to, attempting to ensure that owners receive an adequate return on their investment. Employees are also primary stakeholders who have both legal and moral claims on the organization. Organizations also have specific responsibilities to their customers in terms of producing and marketing goods and services that offer functionality, safety, and value; to local communities, which can be greatly affected by the actions of resident organizations and thus have a direct stake in their operations; and to the other companies with whom they do business. Many social commentators also suggest that companies have a direct responsibility to future generations and to the natural environment. An organization's responsibilities are not limited to primary stakeholders. Although governmental bodies and regulatory agencies do not usually have ownership stakes in companies in free-market economies, they do play an active role in trying to ensure that organizations accept and meet their responsibilities to primary stakeholder groups. Organizations are accountable to these secondary stakeholders. Organizations must also contend with civic and special interest groups that purport to act on behalf of a wide variety of constituencies. Trade associations and industry groups are also affected by an organization's actions and its reputation. The media reports on and investigates the actions of many companies, particularly large organizations, and most companies accept that they must contend with and effectively "manage" their relationship with the media. Finally, even an organization's competitors can be considered secondary stakeholders, as they are obviously affected by organizational actions. For example, one might argue that organizations have a social responsibility to compete in the marketplace in a manner that is consistent with the law and with the best practices of their industry, so that all competitors will have a fair chance to succeed. CONTEMPORARY SOCIAL ISSUES Corporations deal with a wide variety of social issues and problems, some directly related to their operations, some not. It would not be possible to adequately describe all of the social issues faced by business. This section will briefly discuss three contemporary issues that are of major concern: the environment, global issues, and technology issues. There are many others. ENVIRONMENTAL ISSUES. Corporations have long been criticized for their negative effect on the natural environment in terms of wasting natural resources and contributing to environmental problems such as pollution and global warming. The use of fossil fuels is thought to contribute to global warming, and there is both governmental and societal pressure on corporations to adhere to stricter environmental standards and to voluntarily change production processes in order to do less harm to the environment. Other issues related to the natural environment include waste disposal, deforestation, acid rain, and land degradation. It is likely that corporate responsibilities in this area will increase in the coming years. GLOBAL ISSUES. Corporations increasingly operate in a global environment. The globalization of business appears to be an irreversible trend, but there are many opponents to it. Critics suggest that globalization leads to the exploitation of developing nations and workers, destruction of the environment, and increased human rights abuses. They also argue that globalization primarily benefits the wealthy and widens the gap between the rich and the poor. Proponents of globalization argue that open markets lead to increased standards of living for everyone, higher wages for workers worldwide, and economic development in impoverished nations. Many large corporations are multinational in scope and will continue to face legal, social, and ethical issues brought on by the increasing globalization of business. Whether one is an opponent or proponent of globalization, however, does not change the fact that corporations operating globally face daunting social issues. Perhaps the most pressing issue is that of labor standards in different countries around the world. Many corporations have been stung by revelations that their plants around the world were "sweatshops" and/or employed very young children. This problem is complex because societal standards and expectations regarding working conditions and the employment of children vary significantly around the world. Corporations must decide which is the responsible option: adopting the standards of the countries in which they are operating or imposing a common standard world-wide. A related issue is that of safety conditions in plants around the world. Another issue in global business is the issue of marketing goods and services in the international marketplace. Some U.S. companies, for example, have marketed products in other countries after the products were banned in the United States. TECHNOLOGY ISSUES. Another contemporary social issue relates to technology and its effect on society. For example, the Internet has opened up many new avenues for marketing goods and services, but has also opened up the possibility of abuse by corporations. Issues of privacy and the security of confidential information must be addressed. Biotechnology companies face questions related to the use of embryonic stem cells, genetic engineering, and cloning. All of these issues have far-reaching societal and ethical implications. As our technological capabilities continue to advance, it is likely that the responsibilities of corporations in this area will increase dramatically. Corporate social responsibility is a complex topic. There is no question that the legal, ethical, and discretionary expectations placed on businesses are greater than ever before. Few companies totally disregard social issues and problems. Most purport to pursue not only the goal of increased revenues and profits, but also the goal of community and societal betterment. Research suggests that those corporations that develop a reputation as being socially responsive and ethical enjoy higher levels of performance. However, the ultimate motivation for corporations to practice social responsibility should not be a financial motivation, but a moral and ethical one. Stakeholders and Corporate Social Responsibility These stakeholder groups form the basis of success and failure of the business. Stakeholders are individuals or groups that have interests, rights, or ownership in an organization and its activities. Customers, suppliers, employees, and shareholders are example of primary stakeholder groups. Each has interest in how an organization performs or interacts with them. These stakeholder groups can benefit from a company’s success and can be harmed by its mistakes. Secondary stakeholders are also important because they can take action that can damage or assist the organization. Secondary stakeholders include governments (especially through regulatory agencies), unions, nongovernmental organizations (NGOs), activities, political action groups, and the media. In orders to serve their stakeholders in an ethical and social manner, more and more organizations are adapting the model of corporate social responsibility. The term Corporate Social Responsibility goes by many other terms such as corporate citizenship, responsible business or simply corporate responsibility. When an organization builds ethical and social elements in its operating philosophy and integrate them in its business model, it is said to have possessed a self-regulating mechanism that guides, monitor and ensure its adherence to law, ethics, and norms in carrying out business activities that ensures the serving the interest of all external and internal stakeholders. In other words, the objective of being socially responsible business is achieved when its activities meet or exceed the expectations of all its stakeholders. Here is a model for evaluating an organization’s social performance. The model indicates that total corporate social responsibility can be subdivided into four criteria-economic, legal, ethical and discretionary responsibilities. These responsibilities are ordered from bottom to top in the following illustration. Let’s discuss each one them briefly. Economic responsibilities: The first criterion of social responsibility is economic responsibility. The business institution is, above all, the basic economic unit of society. Its responsibility is to produce goods and services that a society wants and to maximise profit for its owners and shareholders. Economic responsibilities, carried to the extreme, is called profit-maximizing view; it was advocated by Nobel economist Milton Friedman. This view argued that a company should be operated on a profit-oriented basis, with its sole mission to increase its profits so long as is stays withing the rule of the game. The purely profit-maximizing view is no longer considered an adequate criterion of performance in the world in general. Treating economic gain in the social as the only social responsibility can lead companies into trouble. Legal responsibilities All modern societies lay down ground rules, laws and regulations that businesses are expected to follow. Legal responsibility defines what society deems as important with respect to appropriate corporate behavior. Businesses are expected to fulfil their economic goals within the legal framework. Legal requirements are imposed by local councils, state and federal governments and their regulating agencies. Organizations that knowingly break the law are poor performers in this category. Intentionally manufacturing defective goods or billing a client for work not done is illegal. Legal sanctions may include embarrassing public apologies or corporate ‘confessions’. Ethical responsibilities Ethical responsibility include behavior that is not necessarily codified into law and may not serve the organization’s direct economic interests. To be ethical, organization’s decision makers should act with equity, fairness and impartiality, respect the rights of individuals, and provide different treatments of individual only when differences between them are relevant to the organization’s goals and tasks. Unethical behavior occurs when decisions enable an individual or organization to gain expense of society. Discretionary responsibilities Discretionary responsibility is purely voluntary and guided by an organization’s desire to make social contributions not mandated by economics, laws or ethics. Discretionary activities include generous philanthropic contributions that offer no payback to the organization and are not expected. Discretionary responsibility is the highest criterion of social responsibility, because it goes beyond societal expectations to contribute to the community’s welfare.

types of visitor

TYPES OF VISITORS Visitors With Appointments: Visitors who have appointments will not always arrive at the exact time scheduled. Those who arrive early should realize that they may have to wait. Those who have appointments should not be kept waiting, but realistically an executive may not be able to stay on a precise schedule. If the visitor appear annoyed, you may suggest that another appointment be arranged or perhaps. You offer to get the visitor a cup of coffee and indicate that the latest issue of a magazine. While the person is waiting, you should maintain a business like attitude. Visitors Without Appointments: When you do not recognize those who come to your office without appointments, you need to determine who they are and what they want. Embarrassing situations may result from untrue statements concerning why the executive cannot see a visitor. Your boss may want to be available to some people at all times. Certainly, higher- ranking executives and their secretaries do not need permission to enter your boss’s office, but they usually ask or give an opportunity to indicate whether he or she is busy. Relatives, close friends and executives on the same level generally have access to the boss’s office Problem Visitors: If a visitor to your office becomes irate, you must do all you can to maintain goodwill. One of the best ways to avoid becoming defensive is to remember that unless you are the one whose actions created the problems, the visitor’s remark are not about you. Be attentive listen carefully until the visitor has finished talking. After you have listened to what the visitor has to say you may know how the problem can be resolved. PERSONAL QUALITIES OF A SECRETARY 1 A Secretary Should Be Cost Conscious: He must have ability to organize ideals, improve things and avoid waste in his daily activities. 2 A Secretary Should Be Cheerful And Hospitable: In his day to day activities the office worker interacts with people of different social and psychology disposition. To make such people come again, the secretary ought to radiate joy in his inter-face with them. 3 To Work Well Under Pressure: A secretary must possess the ability to work under pressure. When work and responsibilities mount and unwieldy the secretary should be clam, under there are too many tasks awaiting treatment on your table, you should as a secretary, be peaceful and clam. 4 Be Tactful, Discrete And Diplomatic In Relating To Visitors And Callers: He must release that he is a keeper of secret and should be careful in letting out secret information to authorized person, being tactful required visitors and his employers. 5 To Be A Good Communicator In Speech And Writer: Be “phonogenic” in oral and telephone conversations. To be “phonogenic”, he needs to pronounce word appropriately using the correct consonants, vowels, diphthong, diction and style. A secretary avoids native language interference in his office communication. CONCLUSION A secretary has many reception duties required of him. These duties were mostly related to correspondence, such as typing out letters. The advent of words processing has significant reduced the time that such duties require. A secretary is often the first business contact a person will meet at any organization. These are many qualities that a secretary is expected to possess in order to do the jobs successfully include attentiveness, a well groomed appearance, loyalty, maturity etc. Furthermore it is emphasized that the secretary must possess or be acquainted with some personal qualities/characteristics that will make her quite unique in the office. Her ability to get along with members within and outside the organization is important. The study portrayed those receptionist duties required as a yardstick for any secretary who wishes to be successful in the secretarial profession. RECOMMENDATION 1) A formal study of training programme should be organized for secretaries on receptionist duties this will further enhance the secretary’s performance and in dealing with people in the industry because adequate and better receptionist duties is an essential factor for efficient and effective of nay organization. 2) god receptionist duties is an essential tool and imperative factors that should be cultivated, sustained and maintained by secretaries, management and other members of any establishment for the attainment of organizational goals.

nepad

INTRODUCTION The new partnership for Africa’s development (NEPAD) is a vision and strategic framework for Africa’s renewal, the NEPAD strategic framework document arises from a mandate given to the five initiating heads of state (Algeria, Egypt, Nigeria, Senegal, south Africa) by the organization of African unity (OAU) to develop an integrated socio-economic development framework for Africa. The 37th summit of the OAU in July 2001 formally adopted the strategic framework document. ORIGIN The New Partnership for Africa's Development (NEPAD) is an economic development program of the African Union. NEPAD was adopted at the 37th session of the Assembly of Heads of State and Government in July 2001 in Lusaka, Zambia. NEPAD aims to provide an overarching vision and policy framework for accelerating economic co-operation and integration among African countries. It is in this regard that the New Partnership for Africa's Development (NEPAD) is the result of three parallel initiatives. The first is the Millennium Africa Recovery Plan (MAP), led by South African President Thabo Mbeki and unveiled at the World Economic Forum in Davos in January 2001. The second initiative is the Omega Plan, crafted by the President of Senegal, Abdoulaye Wade, and presented to the Summit of Francophone African leaders in Cameroon in January 2001. MAP and the Omega Plan were then combined to give birth to a third initiative the New African Initiative (NAI) that then led to NEPAD in 2001. All three initiatives shared a common interest in increasing the pace and impact of Africa's development. While these initiatives share common characteristics, there were also differences reflecting the regional and other priorities of the enactors. Compromises had to be made in order to merge the three proposals into one initiative. NEPAD thus reflects the compromises involved in arriving at a single initiative. Founding member countries of NEPAD included South Africa, Nigeria, Algeria, Egypt and Senegal. NEPAD was adopted by African Heads of State and Government of the OAU in 2001 and was ratified by the African Union (AU) in 2002 to address Africa's development problems within a new paradigm. NEPAD's main objectives are to reduce poverty, put Africa on a sustainable development path, halt the marginalization of Africa, and empower women. The mechanism for Africa's development – today and tomorrow Since its initiation, NEPAD has been promoted widely both within Africa and in the industrialised North. NEPAD is now recognised as Africa's development plan by all the governments of the North, and the international financial institutions, and by many international governance institutions like the United Nations. NEPAD is widely seen as the mechanism through which support to Africa's development efforts can be best delivered. Thus, the NEPAD process has come to be accepted not only by African countries and RECs but also by Africa's development partners as the framework mechanism for their development efforts. NEPAD is a merger of two plans for the economic regeneration of Africa: the Millennium Partnership for the African Recovery Programme (MAP), led by Former President Thabo Mbeki of South Africa in conjunction with Former President Olusegun Obasanjo of Nigeria and President Abdelaziz Bouteflika of Algeria; and the OMEGA Plan for Africa developed by President Abdoulaye Wade of Senegal. At a summit in Sirte, Libya, March 2001, the Organisation of African Unity (OAU) agreed that the MAP and OMEGA Plans should be merged. The UN Economic Commission for Africa (UNECA) developed a "Compact for Africa’s Recovery" based on both these plans and on resolutions on Africa adopted by the United Nations Millennium Summit in September 2000, and submitted a merged document to the Conference of African Ministers of Finance and Ministers of Development and Planning in Algiers, May 2001.[2] In July 2001, the OAU Assembly of Heads of State and Government meeting in Lusaka, Zambia, adopted this document under the name of the New African Initiative (NAI). The leaders of G8 countries endorsed the plan on July 20, 2001; and other international development partners, including the European Union, China, and Japan also made public statements indicating their support for the program. The Heads of State and Government Implementation Committee (HSGIC) for the project finalized the policy framework and named it the New Partnership for Africa's Development on 23 October 2001. NEPAD is now a program of the African Union (AU) that has replaced the OAU in 2002, though it has its own secretariat based in South Africa to coordinate and implement its programmes. NEPAD seeks to attract increased investment, capital flows and funding, providing an African-owned framework for development as the foundation for partnership at regional and international levels. In July 2002, the Durban AU summit supplemented NEPAD with a Declaration on Democracy, Political, Economic and Corporate Governance. According to the Declaration, states participating in NEPAD ‘believe in just, honest, transparent, accountable and participatory government and probity in public life’. Accordingly, they ‘undertake to work with renewed determination to enforce’, among other things, the rule of law; the equality of all citizens before the law; individual and collective freedoms; the right to participate in free, credible and democratic political processes; and adherence to the separation of powers, including protection for the independence of the judiciary and the effectiveness of parliaments. The Declaration on Democracy, Political, Economic and Corporate Governance also committed participating states to establish an African Peer Review Mechanism (APRM) to promote adherence to and fulfilment of its commitments. The Durban summit adopted a document setting out the stages of peer review and the principles by which the APRM should operate; further core documents were adopted at a meeting in Abuja in March 2003, including a Memorandum of Understanding to be signed by governments wishing to undertake the peer review. Current status Ever since it was set up there has been some tension over the place of NEPAD within the African Unity (AU) programs, given its origins outside the framework of the AU, and the continuing dominant role of South Africa—symbolised by the location of the secretariat in South Africa. Successive African Unity (AU) summits and meetings of the HSGIC have proposed the greater integration of NEPAD into the AU's structures and processes. In March 2007 there was a 'brainstorming session' on NEPAD held in Algeria at which the future of NEPAD and its relationship with the AU was discussed by an ad hoc committee of heads of state. The committee again recommended the fuller integration of NEPAD with the AU. In April 2008, a review summit of five heads of state—Presidents Mbeki of South Africa, Wade of Senegal, Bouteflika of Algeria, Mubarak of Egypt and Yar'Adua of Nigeria—met in Senegal with a mandate to consider the progress in implementing NEPAD and report to the next AU summit to be held in Egypt in July 2008. Structure The HSGIC to which the NEPAD secretariat reports comprises three states for each region of the African Union, with former President Obasanjo (Nigeria) as elected chair, and Presidents Bouteflika (Algeria) and Wade (Senegal) as deputy chairmen. The HSGIC meets several times a year and reports to the AU Assembly of Heads of State and Government. There is also a steering committee, comprising 20 AU member states, to oversee projects and program development. The NEPAD Secretariat is based in Midrand, South Africa. The first CEO was Wiseman Nkuhlu of South Africa (2001–2005), and the second Mozambican Firmino Mucavele (2005–2008). On April 1, 2009, Ibrahim Hassane Mayaki accepted the position as the 3rd CEO. The NEPAD Secretariat is not responsible for the implementation of development programs itself, but works with the African Regional Economic Communities—the building blocks of the African Union. The role of the NEPAD Secretariat is one of coordination and resource mobilisation. Many individual African states have also established national NEPAD structures responsible for liaison with the continental initiatives on economic reform and development programs. Partners • UN Economic Commission for Africa (UNECA) • African Development Bank • Development Bank of Southern Africa (DBSA) • Investment Climate Facility (ICF) • African Capacity Building Foundation • Office of the UN Under-Secretary-General and Special Adviser on Africa • IDC (The Industrial Development Corporation) - Sponsor of NEPAD Programs The eight priority areas of NEPAD are: political, economic and corporate governance; agriculture; infrastructure; education; health; science and technology; market access and tourism; and environment. During the first few years of its existence, the main task of the NEPAD Secretariat and key supporters was the popularisation of NEPAD’s key principles, as well as the development of action plans for each of the sectoral priorities. NEPAD also worked to develop partnerships with international development finance institutions—including the World Bank, G8, European Commission, UNECA and others—and with the private sector. After this initial phase, more concrete programs were developed, including: • The Comprehensive Africa Agriculture Development Programme (CAADP), aimed at assisting the launching of a 'green revolution' in Africa, based on a belief in the key role of agriculture in development. • The Programme for Infrastructure Development in Africa (PIDA) which comprises numerous trans-boundary infrastructure projects in the four sectors transport, energy, water and ICT, aimed at boosting intra-African trade and interconnecting the continent. • The NEPAD Science and Technology programme, including an emphasis on research in areas such as water science and energy. • The "e-schools programme", adopted by the HSGIC in 2003 as an initiative to equip all 600,000 primary and secondary schools in Africa with IT equipment and internet access within 10 years, in partnership with several large IT companies. See NEPAD E-School program • The launch of a Pan African Infrastructure Development Fund (PAIDF) by the Public Investment Corporation of South Africa, to finance high priority cross-border infrastructure projects. • Capacity building for continental institutions, working with the African Capacity Building Foundation, the Southern Africa Trust, UNECA, the African Development Bank, and other development partners. One of NEPAD's priorities has been to strengthen the capacity of and linkages among the Regional Economic Communities. • NEPAD was involved with the Timbuktu Manuscripts Project although it is not entirely clear to what extent. Criticism NEPAD was initially met with a great deal of scepticism from much of civil society in Africa as playing into the 'Washington Consensus' model of economic development. In July 2002, members of some 40 African social movements, trade unions, youth and women's organizations, NGOs, religious organizations and others endorsed the African Civil Society Declaration on NEPAD[8] rejecting NEPAD; a similar hostile view was taken by African scholars and activist intellectuals in the 2002 Accra Declaration on Africa's Development Challenges. Part of the problem in this rejection was the process by which NEPAD was adopted was insufficiently participatory—civil society was almost totally excluded from the discussions by which it came to be adopted. More recently, NEPAD has also been criticised by some of its initial backers, including notably Senegalese President Abdoulaye Wade, who accused NEPAD of wasting hundreds of millions of dollars and achieving nothing. Like many other intergovernmental bodies, NEPAD suffers from slow decision-making, and a relatively poorly resourced and often cumbersome implementing framework. There is a great lack of information about the day-to-day activities of the NEPAD secretariat—the website is notably uninformative—that does not help its case. However, the program has also received some acceptance from those initially very critical, and in general its status has become less controversial as it has become more established and its programs have become more concrete. The aim of promoting greater regional integration and trade among African states is welcomed by many, even as the fundamental macroeconomic principles NEPAD endorses remain contested. ACHIEVEMENT NEPAD achievements during the first 5 years, NEPAD has come about as a result of the merger between the Millennium Partnership for Africa’s Recovery Programme (MAP) and OMEGA plan, which was finalised on 3 July 2001. Out of this merger, the New African Initiative (NAI) was formed. The NAI Policy Framework was finalised by the Heads of State and Implementation Committee of the OAU (now AU) on 23 October 2001 and NAI was renamed to NEPAD on the day. This brief makes a summarised assessment of the achievements by NEPAD as it has reached the age of five. It should however be noted that the short term action plan of NEPAD started later in 2002 and what is assessed here is NEPAD itself based on its far-reaching programmes. It is pointed out in this briefing that NEPAD has achieved a lot in terms of gaining international recognition; getting the African civil society on board; promoting good governance through peer reviews; developing regional infrastructure; and promoting agricultural activity. One notable event where NEPAD made its mark on the international stage was the G8 summit that took place in Canada in June 2002. At that meeting, four promoters of NEPAD, together with the UN Secretary-General were invited to discuss challenges facing Africa, and for the G8 to give its first response to the NEPAD plan. This has resulted in the adoption of the G8 African Action Plan as a framework to support African countries whose performance reflects the commitments of NEPAD. Under the plan, the G8 indicated their increased commitment to support Africa under various initiatives, including the HIPC, enhanced HIPC, ODA, and the Global Fund to fight HIV/AIDS, malaria and TB. The organisation of various regional workshops that brought together stakeholders from civil society, business and government sectors were another achievement. The main aim of these workshops is to increase awareness amongst all stakeholders about the plan and to urge stakeholders to implement it. Hanns Seidel Foundation has taken a lead in organising such workshops in Southern and Eastern Africa. Another achievement, which is also linked to the first two, is the extensive coverage of NEPAD in literature and media, in Africa and abroad, and from different disciplines of science. The African Peer Review Mechanism of NEPAD that works to promote democracy and good governance has already produced results. The review reports from Ghana and Kenya have been published, while the same process is at an advanced stage in further nine countries. NEPAD has done well in the area of regional infrastructure development since 2002. Over US$530 million has already been used in the development of roads, communications and energy networks, while projects worth around US$490 million were under consideration during 2005. Furthermore, NEPAD has formulated an Agricultural Development Plan whereby member states of the AU have committed themselves to develop pro-development policies and to allocate sufficient resources to the sector. Among its achievements, that are cited in the NEPAD Briefing 15, are gaining international recognition, getting African civil society on board, promoting good governance through peer reviews, developing regional infrastructure and also promoting agricultural activities. NEPAD PRIMARY OBJECTIVES • To eradicate poverty; • To place African countries, both individually and collectively, on a path of sustainable growth and development; • To halt the marginalisation of Africa in the globalisation process; • To accelerate the empowerment of women; • To fully integrate Africa into the global economy OTHER OBJECTIVES NEPAD provides an historic opportunity to overcome obstacles to development in Africa. Our contribution to the initiative is the creation of NEPAD Council, designed to encourage the imaginative effort that underlies the NEPAD and to lay a solid foundation for future cooperation and sustainable development. The case for action is compelling. Despite its great potential and human resources, Africa continues to face some of the world’s greatest challenges. The many initiatives designed to spur Africa’s development have failed to deliver sustained improvements to the lives of women, men and children throughout Africa. NEPAD Council offers something different. It is, first and foremost, a common vision shared by African professionals to support and promote the New Partnership for Africa’s Development. Together, we have an unprecedented opportunity to make progress on our common goals of eradicating extreme poverty and achieving sustainable development. NEPAD Council will support African leaders’ efforts to encourage public engagement in the NEPAD and will consult with NEPAD members on how we can best assist their efforts. NEPAD Council will be committed to mobilize and energize global action, marshal resources and expertise, and provide impetus in support of NEPAD’s objectives. As NEPAD’s partner, NEPAD Council will undertake mutually reinforcing actions to help Africa accelerate growth and make lasting gains against poverty. The Agenda of NEPAD Council will focus on a limited number of priority areas where, collectively and individually, we can add value. NEPAD Council will focus particular attention on enhanced-partnership countries. It will also work with countries that do not yet meet the standards of NEPAD but which are clearly committed to and working towards its implementation. The objectives of NEPAD Council include: 1. Support the new partnership for Africa’s Development 2. Support African leaders’ efforts to encourage public engagement in NEPAD strategies and projects 3. Assist the Steering Committee and NEPAD 4. Secretariat in the implementation of NEPAD projects 5. Collaborate with NEPAD to undertake mutually reinforcing actions to help accelerate growth and make long-lasting gains against poverty 6. Encourage Africans in the Diaspora to actively participate in all efforts aimed at developing Africa "NEPAD Council offers something different. It is, first and foremost, a common vision shared by African professionals to support and promote the New Partnership for Africa’s Development." CONCLUSION Our interest in NEPAD is a simple one. It is a call that NEPAD should be accepted on the ground that Africa requires a development blueprint. This acceptance should not be uncritical. NEPAD must not be regarded as a finished and closed document that cannot accommodate the high points other pan-African and national development blueprints. Our suggestions point out to one problem NEPAD is bound to face. NEPAD has wholesomely and uncritically adopted ‘neo-liberal democracy’ cum Keynesian free market political economy. But Africa requires more of a social democracy, especially those practiced in States that were challenged with the task of revamping their economies and putting themselves on the path of development. Germany is a good example in this light. No development is possible in Africa except majority of its people who are rural dwellers and have been historically disconnected from the State and indeed productions are reconnected to these institutions and functions. Today, the African productive class is one that is unemployed, a hawker and loafer in the city, or one who is seeking to escape to Europe, the United States of America or some other developed societies. NEPAD is the appreciation of the fact that undue ‘economism’ has failed to deliver in Africa for over 40 years. REFERENCES Adedeji and T.

social

Social responsibility Social responsibility is an ethical framework which suggests that an entity, be it an organization or individual, has an obligation to act for the benefit of society at large. Social responsibility is a duty every individual has to perform so as to maintain a balance between the economy and the ecosystems. A trade-off may[citation needed] exist between economic development, in the material sense, and the welfare of the society and environment. Social responsibility means sustaining the equilibrium between the two. It pertains not only to business organizations but also to everyone whose any action impacts the environment.[1] This responsibility can be passive, by avoiding engaging in socially harmful acts, or active, by performing activities that directly advance social goals. Businesses can use ethical decision making to secure their businesses by making decisions that allow for government agencies to minimize their involvement with the corporation.[2] For instance if a company follows the United States Environmental Protection Agency (EPA) guidelines for emissions on dangerous pollutants and even goes an extra step to get involved in the community and address those concerns that the public might have; they would be less likely to have the EPA investigate them for environmental concerns.[3] "A significant element of current thinking about privacy, however, stresses "self-regulation" rather than market or government mechanisms for protecting personal information".[4] According to some experts, most rules and regulations are formed due to public outcry, which threatens profit maximization and therefore the well-being of the shareholder, and that if there is not outcry there often will be limited regulation.[5] Critics argue that corporate social responsibility (CSR) distracts from the fundamental economic role of businesses; others argue that it is nothing more than superficial window-dressing; others argue that it is an attempt to pre-empt the role of governments as a watchdog over powerful corporations though there is no systematic evidence to support these criticisms. A significant number of studies have shown no negative influence on shareholder results from CSR but rather a slightly negative correlation with improved shareholder returns.[clarification needed][6] Contents • 1 Student social responsibility • 2 Corporate social responsibility • 3 Social Responsibility of Scientists and Engineers • 4 Emerging normative status of social responsibility • 5 See also • 6 Notes • 7 References • 8 Further reading Student social responsibility Student social responsibility is the responsibility of every student for his/her actions. It is morally binding on everyone to act in such a way that the people immediately around them are not adversely affected. It is a commitment everyone has towards the society – contributing towards social, cultural and ecological causes. SSR is based on an individual's ethics. Instead of giving importance only to those areas where one has material interests the individual supports issues for philanthropic reasons. It forms the base for CSR or Corporate Social Responsibility because if everyone in a business organization does his/her bit the bigger things automatically fall into place. The trends however show that big charitable organizations recorded high growth due to the SR efforts of individuals and not corporations or the government. ISR may be slightly impractical, especially in the modern competitive world, where everyone works for self-interest, but it will succeed if we take decisions based on what will benefit a large number of people and respect everyone's fundamental rights. As individuals we can make our small contributions to society by donating money to trustworthy NGO's, saving our resources by reducing our consumption, e.g. by switching off lights or computers when not in use. 2. Corporate social responsibility Corporate social responsibility or CSR has been defined by Lord Holme and Richard Watts in the World Business Council for Sustainable Development’s publication “Making Good Business Sense” as “…the continuing commitment by business to behave ethically and contribute to economic development while improving the quality of life of the workforce and their families as well as the local community and society at large.” CSR is one of the newest management strategies where companies try to create a positive impact on society while doing business. Evidence suggests that CSR taken on voluntarily by companies will be much more effective than CSR mandated by governments.[7] There is no clear-cut definition of what CSR comprises. Every company has different CSR objectives though the main motive is the same. All companies have a two-point agenda—to improve qualitatively (the management of people and processes) and quantitatively (the impact on society). The second is as important as the first and stake holders of every company are increasingly taking an interest in "the outer circle"-the activities of the company and how these are impacting the environment and society.[8] Social Responsibility of Scientists and Engineers One common view is that scientists and engineers are morally responsible for the negative consequences which result from the various applications of their knowledge and inventions.[9][10][11][12][13] After all, if scientists and engineers take personal pride in the many positive achievements of science and technology, why should they be allowed to escape responsibility for the negative consequences related to the use or abuse of scientific knowledge and technological innovations?[14] Furthermore, scientists and engineers have a collective responsibility for the choice and conduct of their work. Committees of scientists and engineers are often involved in the planning of governmental and corporate research programs, including those devoted to the development of military technologies and weaponry.[15][16] Many professional societies and national organizations, such as the National Academy of Science and the National Academy of Engineering in the United States, have ethical guidelines (see Engineering ethics and Research ethics for the conduct of scientific research and engineering).[17] Clearly, there is recognition that scientists and engineers, both individually and collectively, have a special and much greater responsibility than average citizens with respect to the generation and use of scientific knowledge. Unfortunately, it has been pointed out that the situation is not that simple and scientists and engineers should not be blamed for all the evils created by new scientific knowledge and technological innovations.[18] First, there is the common problem of fragmentation and diffusion of responsibility. Because of the intellectual and physical division of labor, the resulting fragmentation of knowledge, the high degree of specialization, and the complex and hierarchical decision-making process within corporations and government research laboratories, it is exceedingly difficult for individual scientists and engineers to control the applications of their innovations.[19] This fragmentation of both work and decision-making results in fragmented moral accountability, often to the point where "everybody involved was responsible but none could be held responsible."[20] Another problem is ignorance. The scientists and engineers cannot predict how their newly generated knowledge and technological innovations may be abused or misused for destructive purposes in the near or distant future. While the excuse of ignorance is somewhat acceptable for those scientists involved in very basic and fundamental research where potential applications cannot be even envisioned, the excuse of ignorance is much weaker for scientists and engineers involved in applied scientific research and technological innovation since the work objectives are well known. For example, most corporations conduct research on specific products or services that promise to yield the greatest possible profit for share-holders. Similarly, most of the research funded by governments is mission-oriented, such as protecting the environment, developing new drugs, or designing more lethal weapons. In all cases where the application of scientific knowledge and technological innovation is well known a priori, it is impossible for a scientist or engineer to escape responsibility for research and technological innovation that is morally dubious.[21] As John Forge writes in Moral Responsibility and the Ignorant Scientist: "Ignorance is not an excuse precisely because scientists can be blamed for being ignorant."[22] Another point of view is that responsibility falls on those who provide the funding for the research and technological developments, which in most cases are corporations and government agencies. Furthermore, because taxpayers provide indirectly the funds for government-sponsored research, they and the politicians that represent them, i.e., society at large, should be held accountable for the uses and abuses of science.[23] Compared to earlier times when scientists could often conduct their own research independently, today's experimental research requires expensive laboratories and instrumentation, making scientists dependent on those who pay for their studies. Emerging normative status of social responsibility Social responsibility as a non-binding, or soft law principle has received some normative status in relation to private and public corporations in the United Nations Educational, Scientific and Cultural Organization (UNESCO) Universal Declaration on Bioethics and Human Rights developed by the UNESCO International Bioethics Committee particularly in relation to child and maternal welfare.[24](Faunce and Nasu 2009) The International Organization for Standardizationrd will "encourage voluntary commitment to social responsibility and will lead to common guidance on concepts, definitions and methods of evaluation."[25] The standard describes itself as a guide for dialogue and language, not a constraining or certifiable management standard.[26] How Companies Can Become More Socially Responsible In a recent article I co-wrote with Milinda Martin, In the Future, Companies Will Only Survive if They Help Solve Big Social Problems, we predicted that “2015 will mark the beginning of a long-term transition of the role and purpose of the world’s largest public companies and the value chains they control” and suggested that “the new imperative for business leaders will be to embrace the idea that the viability of their businesses depends on solving the world’s most pressing societal issues.” The vision for the future we illustrated was based on input from corporate leaders who have observed that most of the ways in which businesses currently contribute to social change aren’t very effective for companies or communities. We suggested that in the years ahead leading businesses would abandon tokenistic corporate social responsibility, commit to bold social goals, and integrate social change in all aspects of their operations. In responding to comments from readers, I realized that we missed an opportunity to help corporations become more effective agents of social change by providing specific ideas for what they should start to do differently in 2015. So here are seven ideas to help executives move their businesses towards a more compelling long-term vision and improve their performance in 2015. 1. Pick a big issue, declare a clear goal, and mobilize your resources. Corporations become successful because they identify problems, allocate resources to uncover and deliver solutions, and are accountable for what happens. The role of business in social change should be no different. Tyson Foods, one of the world’s largest producers of meat and poultry, has a social goal of ending hunger. Through its KNOW Hunger program, Tyson donates to food banks and increases awareness of hunger issues on a large scale. At the end of 2010, Tyson had donated 78 million pounds of protein—enough to serve one meal to every American citizen. 2. Make more effort to engage the millennials in your workforce. Employees of this generation want to be rewarded in ways that go beyond compensation and expect their employers to support their interest in social change. These employees also want to apply what they know to issues that they’re passionate about. This means reduce or eliminating activities that have employees doing menial tasks that don’t contribute to measurable social outcomes. For more about this, refer to MSLGroup’s excellent report, The Future of Business Citizenship. 3. Engage your naysayers. Corporations that include the perspectives of advocacy organizations create opportunities to make meaningful changes. “Nestlé has been engaging much more systematically with stakeholders, even constructively critical ones, to ask them what they expect of us,” said Paul Bakus, that company’s president of corporate affairs, in a recent Forbes.com interview. “This has led to the development of 35 forward-looking commitments covering every area of our business—nutrition, water, rural development, sustainability, and compliance.” 4. Begin to allocate some of your company’s philanthropic giving to social purpose businesses and/or social enterprises. This will establish a base of social investment the results of which can be quantified while you preserve philanthropic commitments that are meaningful to employees and stakeholders. Based on 2013 figures from the Giving USA Foundation, reducing philanthropic contributions by approximately 50% of what they are today would create an annual pool of social finance capital of approximately $8 billion in the U.S. alone. Company More Socially Responsible for the Stakeholders Companies can be torn between two extremes in today's global marketplace. On the one hand, the desire to compete and succeed is the basis for all business activity. Businesses that do not compete do not survive. On the other hand, concerns over environmentalism, social welfare, charity and other humanitarian concerns are also important for businesses because businesses are also expected to be socially responsible on some level. Making your company more socially responsible for stakeholders is no simple task, but there are a few simple steps you can take to get yourself moving in the right direction. Step 1 Assess your current level of participation in social programs. You need to know where you are starting from if you are to determine how to be more socially responsible for your stakeholders. The misalignment of corporate competitiveness with corporate responsibility stems from one of three issues: inexperienced corporate staff, isolation of managers in charge of corporate responsibility from the rest of the business, and a limited or restricted budget. Step 2 Establish goals that are attainable. Taking baby steps to get started and build your corporate responsibility can get you moving in the right direction. Make sure that your goals can be measured to make sure you are moving forward in the right direction. Eliminate waste or take care of other "close to home" responsibilities first. Step 3 Provide detailed reports to your stakeholders to ensure that they know exactly what steps you are taking to improve your socially responsible activity. Use concurrent press releases and other announcements to increase awareness of your company's actions. This will provide the added advantage of creating a picture among the general public of your company as being socially responsible. Step 4 Obtain feedback from stakeholders in the company. Create a system of two-way communication between shareholders and the company when it comes to the cultivation of social responsibility. This method flies in the face of more traditional methods of corporate communication where the company simply tells shareholders about its actions. Instead, this gives the shareholders a stake in what the company does. Step 5 Prioritize your efforts. Take on the simplest tasks first so that you can accomplish them quickly. This will help build your reputation with the rest of the community and give your stakeholders an opportunity to get involved incrementally as you build towards bigger and more ambitious projects. Wade out into the water before jumping or diving in to immerse yourself.
