Portfolio Leader Development: Personally evaluate and develop the appointed leader of each portfolio, ensuring each is functioning as the technical subject matter expert their portfolio needs, and act decisively through coaching, role redefinition, or personnel change when one is not. Read heartbeat delivery metrics, such as sprint predictability, cycle time, and escaped defects, as an early signal of squad or leader health, and use that signal to decide when the right response is coaching, mentoring, closer management, or replacement.
