Planning allows us to define what you are going to do, when you are going to do it and how you the project goals will be accomplished. Documenting planning activities provides the project manager the opportunity to communicate to project stakeholders, obtain support from team members, and set up a basis on which to analyze and manage the impacts of change. For a small project, the planning cycle should be short. Scalability is especially important during planning. The effort required to plan the project depends on the type and amount of information and the level of detail that needs to be communicated. The duration required to plan depends on the length of time necessary to discover and document the information, as well as the time required to gain agreement with the sponsor on scope, schedule, and cost.

The planning process allows the project manager to collect requirements and develop all the necessary planning documents, including the project scope, work breakdown structure (WBS), project schedule, budget, risk response plan, and communications plan, all of which can then be incorporated into a formal project plan. Sometimes, projects schedule mistakenly considered as a project planning, when in reality the project schedule is only a part of the planning documents. Small project might not require developing a formal project plan or fully developed planning documents.
