Plain definition
What it means.
Delegation of authority is the formal mechanism by which decision-making power is transferred from a senior role, such as the board or CEO, to a more junior role with defined scope, dollar limits, and conditions. It is documented in a delegation of authority policy or matrix and approved by the board or chief executive.
A delegation of authority typically defines who can sign contracts, who can authorize expenditures, who can hire or terminate employees, who can commit to vendor agreements, and at what limits each authority engages. The delegation is conditional and revocable. It expires when the role changes, when limits are exceeded, or when the delegation is formally rescinded.
Delegation of authority is what turns a senior person's job description into actual operating authority for the people who report to them. Without it, every decision flows back to the top.
The same rule applies to small customer-facing problems. Assigning a task is incomplete when the person cannot make the item safe, use an approved resource, act inside a stated limit, escalate the exception, or verify that the result is restored. The workflow moved. Authority did not.
