Dr. Mindy Hall talks about how an organization’s culture is one of the most powerful levers leaders have for impacting performance. Culture is the social energy built over time that can move people to act or impede them from acting. An organization’s culture is never neutral; it will develop by design or default. The question for leaders then is whether they will actively shape their organization’s culture, or allow themselves to be shaped by it. Culture is not a program that gets implemented; it is built through everyday actions and messaging.
