Episode notes
Hierarchy With Authority At The Edge
- The Marine Corps pairs a tall hierarchy with authority at the information source so decisions happen where the facts are, not only at the top.
- Tanner recounts General Mattis's rule: meetings don't end until someone asks a tough question, forcing decisions and action.
Rule Of Three Simplifies Leadership Focus
- The rule of three structures units recursively so leaders focus on three direct reports rather than dozens, limiting micromanagement.
- Tanner describes fire teams, squads, platoons, and the five-paragraph order that labels one primary and two supporting efforts.
Limit Priorities To Three
- Limit work priorities to three and publicly label one as the primary effort so teams know what to sacrifice when new tasks arrive.
- Tanner suggests socializing those three and negotiating which gets swapped out when a fourth item appears.
