We study the interaction between a group of agents who exert effort to complete a project and a
manager who chooses its objectives. The manager has limited commitment power so that she can
commit to the objectives only when the project is sufficiently close to completion. We show that the
manager has incentives to extend the project as it progresses. This result has two implications.
First, the manager will choose a larger project if she has less commitment power. Second, the
manager should delegate the decision rights over the project size to the agents unless she has
sufficient commitment power.
