Marshall Ganz is senior lecturer in public policy at the Kennedy School of Government, Harvard University. His WebEx presentation introduces us to the skills and practices of Community Organizing in which he has both extensive practical and academic expertise. Marshall believes organising is a form of leadership that looks to ask and answer 3 questions. Who are my constituency, what is the challenge they face and what resources do they have? Addressing these questions involves the 5 practices of shared story, shared commitment, shared structure, shared strategy and shared action. Marshall defines leadership as “accepting responsibility for enabling others to achieve purpose under conditions of uncertainty”. This sort of leadership enables a constituency to turn its resources into power to effect the change they desire. Health systems across the world, including CMH, are exploring these ideas as they seek new ways to address the challenge of increased demand for health services in an environment of constrained supply.
