The world is undergoing major transitions due to three driving forces—population changes, climate changes, and energy resource constraints—making it essential for us to move toward sustainability in the implementation of projects and programs as well as our everyday life. Real sustainability exists where there is a balance between population and energy usage and a stable climate—global equilibrium. Designed for program and portfolio managers and senior planners, Sustainable Program Management provides essential information on the three major driving forces of the coming decades and presents options to assist us in moving toward a sustainable future. This book offers a unique approach to accommodating the three new constraints of population change, climate change, and energy resources as impacts on programs and portfolios. It presents them in the form of overlays, which facilitate planning by considering the effects of these additional constraints on a program, along with schedule, budget, and performance constraints. The overlays summarize the book’s extensive analyses of these global challenges. The book is divided into sections on population change, climate change, and energy resource constraints and provides background information and overlays for each one. The author discusses scenarios, possible solutions, and probable outcomes, which provide the basis for evaluating the risks and the sustainability considerations involved. The final section of the text addresses planning for real sustainability and describes six pathways toward a sustainable system. This practical book familiarizes readers with these new global challenges to program management and provides a basis for developing sustainable and successful programs.
