This volume represents the first textbook of the Maturity Institute, a new, not-for-profit, multi-disciplinary professional development institution established in 2012 to address the developmental needs of corporations. It explains the institution's brief history, philosophy, goals, principles, strategic framework and measurement of mature, management practice. It offers a critique of earlier attempts to temper and moderate the worst excesses of late 20th century capitalism including concepts of `balanced scorecards', `triple bottom lines' and `corporate social responsibilities'. It tackles the root causes of capitalism's present malaise, tracing them back to the mantra of `shareholder value'. In its analysis, the text describes a mutually inclusive, whole system, value paradigm where every societal stakeholder can benefit from corporate activity, where true wealth creation, resource utilisation and sustainability go hand-in-hand. This book provides a sophisticated, yet practical, navigation chart for all organisations needing to address the immense social and economic changes of the unfolding millennium.
