What is Project Planning? | Project Manager Questions

Project Planning defines in detail the project activities and the product that will be produced, and describes how the project activities will be accomplished. Project Planning defines all major tasks, estimates the time and resources necessary to complete them, and provides a framework for management review and control.
Project Planning activities include defining and documenting the following:
? Work to be performed,
? Project goals,
? Estimates for planning, tracking, executing, and controlling the project,
? Commitments of the affected groups, and
? Project alternatives, assumptions, and constraints

Planning is a process that includes activities to estimate the size of the project, the scope of the effort, and the resources required to complete the project, as well as steps to produce a project schedule, identify, assess and manage risks, and negotiate commitments. Several iterations of the planning process may be performed
before the Project Plan is completed.
