The prime work of leader is to help build as self-organizing team. This is where the team feels and acts with shared responsibility for how they do as a team. They share responsibility for organization, planning, adapting, communicating, learning and decision making.
This is done through telling and facilitating success and progress stories, asking good questions, giving useful feedback and filling gaps when needed. Self-organizing teams outperform leader-dependent teams by multiple factors. They are more mindful, agile and creative. They flex better to the natural uncertainties and demand-supply imbalances that come with any kinds of growth curves.
