LegitimacyLegitimacy is authority. Authority is typically formally defined by a firm's organizational structure and can be delegated.
UrgencyThe degree to which a stakeholder pushes their ideas forward. This ranges from a stakeholder who completely dominates every conversation to a stakeholder who is disengaged or effectively absent.
