Peter Senge is a Senior Lecturer in Leadership and Sustainability at the MIT Sloan School of Management. The Journal of Business Strategy (September/October 1999) named Senge one of the 24 people who has had the greatest influence on business strategy over the last 100 years. The Financial Times (2000) named him one of the world’s top management gurus, and BusinessWeek (October 2001) rated Senge one of the top 10 management gurus. Senge has lectured extensively throughout the world, translating the abstract ideas of systems theory into tools for better understanding of economic and organizational change. He studies decentralizing the role of leadership in organizations so as to enhance the ability of employees to work productively toward common goals, and the managerial and institutional changes needed to build more sustainable enterprises—those businesses that foster social and natural as well as economic well-being. Senge’s work articulates a cornerstone position of human values in the workplace: namely, that vision, purpose, reflectiveness, and systems thinking are essential if organizations are to realize their potential. He has worked with leaders in business, education, civil society, healthcare, and government.
