A plan for commitment should represent the customer's intent in a way that calls for action on the intent's behalf. A promise to commit to a plan happens at many levels and in many forms toward execution, and every promise made becomes a push mechanism to keep that promise. Since a plan represents both push and pull around a commitment, knowledge about these mechanisms can help to understand a plan's function. The main contribution is a reflection on how a plan's push for commitment interacts with emergent situations and an analysis of what part of the commitment is within or outside the scope of the promise and the promiser's influence and control. The promise made committing to a workplan as input to a Percent Plan Complete measurement is used as a practical example. The paper's conclusion arguably strengthens many of the existing parts and principles of the Last Planner System but also gives suggestions for improvement.
