Why is ethics important to organizations? What are the characteristics of an ethical organization? How can we audit the ethics of an organization? What measures and activities stimulate the ethical development of organizations? This text addresses these questions. It is easier to say that ethics is necessary than to tell how to organize ethics. This text provides a vision on how ethics can be organized in a focused way. The study examines the assumptions for organizing ethics, the pitfalls and phases of such a process, the parts of an ethics audit and the great variety of measures. The methods and insights illustrated in this book are based partially on practical research. One of these methods, the Ethics Thermometer, was based on more than 150 interviews at various organizations. The Ethics Thermometer has been applied in a great variety of profit and not-for-profit organizations in order to measure an organization's perceived context, conduct and consequences. This book should be of interest to scholars in the field of business ethics, as well as to managers and practitioners. For scholars, this study provides general knowledge about auditing and developing the ethics of an organization. A summary is given of the criteria by which the ethical content of an organization can be measured. For managers and practitioners, this study provides concrete suggestions for safeguarding and improving ethics within their organizations.
