Compare Delegation Models: Situational Leadership vs Task-Maturity

You are setting a consistent delegation approach across your managers and the leadership models all blur together. This compares Blanchard's Situational Leadership II against Hersey's original task-maturity model: the core premise of each, what a manager has to assess, and how each plays out day to day. For senior leaders choosing one language for the whole team.

I'm a senior leader building a consistent delegation and coaching approach across my management team. Compare the following two models in depth: (1) Situational Leadership II (Blanchard's D1 to D4 / S1 to S4 model) and (2) the Task-Maturity approach from Hersey's original Situational Leadership model. For each model cover: the core premise, the key variables a manager must assess, how it translates into day-to-day delegation decisions, its strongest use cases, and its known limitations. Then give me a practical recommendation: which model (or hybrid approach) is most applicable for a {TEAM_TYPE} team in a {INDUSTRY} environment, and why. Include a one-page decision guide I can share with my management team to help them apply the chosen model consistently.
