Reference #263: The First 90 Days
The extremes of how a team makes decisions are unilateral decision making — where the leader simply makes a call — and unanimous consent.
The former risks both a poor decision (for lack of critical information) and a limited amount of necessary buy-in to implement the decision.
The latter, when more than a few people are involved, suffers from decision diffusion and never reaches closure. When a decision is reached, it is often a lowest common denominator compromise.
Either extreme leads to critical opportunities and threats not being addressed.
