Project planning is an important part of project management. This paper argues against the commonly used practice of activity planning. It claims that this kind of planning at an early stage is either impossible to do in a meaningful way or gives miserable results. It proposes milestone planning as an alternative approach. Milestone planning is goal-directed and results-oriented, and not activity-based. A project responsibility chart is used to clarify the responsibilities for achieving the different milestones. A different approach to scheduling is suggested. The proper role for detailed activity planning is described.
