For every objective, ensure unity of effort under one responsible commander.

In a planning situation it is important to establish a command or authority hierarchy. A specific individual must accept personal accountability for approving plans and actions.

This tip is sometimes interpreted as "have one boss" and that is the general thrust. The commander can delegate, but it is important to know who is in command in a situation.

A person should have one and only one manager to whom he or she is directly responsible.

Each person in an organization should take orders from and report to only one person.
