Using the space shuttle program as the framework, this book examines the role of ethical decision making in the practice of engineering. In particular, the book considers the design and development of the main engines of the space shuttle as a paradigm for how individual engineers perceive, articulate, and resolve ethical dilemmas in a large, complex organization. A series of in-depth case studies shows engineers at work on various stages of the project as they balance budgets, deadlines, and risks. By documenting the historical development of a single system, the book provides a unique opportunity to explore the complex interactions between political, organizational, and technical pressures and engineering and management decisions. Both students and engineers will gain valuable insight into ethical dilemmas common to engineering practice and to ethical decision making.
