Despite the differences between business and social-sector economics, a fundamental truth remains. Those who lead institutions from good to great must harness the flywheel effect. Whereas in business the key driver in the flywheel is the link between financial success and capital resources, I’d like to suggest that a key link in the social sectors is brand reputation built upon tangible results and emotional share of heart, with potential supporters believing in not only your mission but also your capacity to deliver on that mission.
