Situational leadership focuses on assessing the development level of team members and flexibly adjusting leadership style to fit the situation. There are four development levels based on competence and commitment, from lowest to highest: D1, D2, D3, and D4. The four leadership styles range from directing to delegating based on the amount of direction and support provided. An effective leader will diagnose where team members fall in terms of development and apply the appropriate leadership style to help move them towards higher performance.
