Delegation fails most often because the person handing off work never said how much authority came with it. In a widely used example, a manager believed he had delegated an event at "research and report" while the person doing the work assumed full authority to act, and the gap only surfaced after the fact. The manager's conclusion was blunt: the fault was his for not clarifying the level when he delegated (Full Focus). Harvard Business School Online makes the same point from the other direction: if the person receiving work needs training, resources or authority to complete it, providing all three is the manager's job (HBS Online).
The business case is not soft. A Gallup study cited by HBS Online found that CEOs who delegate well generate 33 percent higher revenue (HBS Online). Managers spend roughly 37 percent of their time making decisions, and more than half of that time is wasted, according to McKinsey research summarized by Prialto (Prialto). Most of that waste is not analysis. It is people waiting to find out whether they were allowed to decide.
Agents make the problem sharper, not different. A useful definition of "intelligent delegation" for AI systems covers task allocation plus "transfer of authority, responsibility, accountability, clear specifications regarding roles and boundaries, clarity of intent, and mechanisms for establishing trust" (arxiv). That is the same list a good manager would recognize. The difference is that an agent will not pause to wonder whether it has authority. It will simply proceed, which is why the level has to be written down.
