Artificial intelligence (AI) has permeated every aspect of life. Like every other technology, AI poses risk and raises questions on ethics related to its design, development, deployment, use, and retirement. While a completely ethical AI may not be possible to achieve, it is possible to assess the maturity of the ethics of certain AI-based system, or that of an organization that employs AI. This book presents a comprehensive framework designed to guide organizations in assessing and enhancing the ethical maturity of their AI systems. It provides a structured approach to evaluating AI ethics across multiple dimensions, including governance, transparency, accountability, fairness, and privacy. By using this framework, organizations can identify areas of strength and opportunities for improvement, enabling them to develop AI systems that are not only technically robust but also ethically sound. This book is just the beginning of a whole new domain of AI ethics maturity assessment in which the author plans to establish a certification body for certifying systems and organizations on the maturity of their AI ethics. The author may be approached for partnership in this regard at azharzr@usa.net.
