This document discusses different approaches to planning and the purpose of planning. It describes planning as a conscious, systematic process to determine goals and actions for the future. There are four main approaches discussed: top-down, bottom-up, composite, and team. The top-down approach centralizes planning at the top level while the bottom-up approach has lower levels draft plans. The composite approach involves discussion and debate between levels. The team approach assigns a team to develop plans. Finally, the document lists nine purposes of planning, such as facilitating objectives, ensuring economy, and coordinating activities.
