Especially for large projects, it is very muchdifficult to make accurate plans. A part of this difficulty is due to the fact that the properparameters, scope of the project, project staff, etc. may change during the span of the project. Inorder to overcome this problem, sometimes projectmanagers undertake project planning instages.Planningaprojectoveranumberofstagesprotectsmanagersfrommakingbigcommitments too early. This technique of staggered planning is known as Sliding WindowPlanning. In the sliding window technique, starting with an initial plan, the project is plannedmore accurately in successive development stages. At the start of a project, project managershave incomplete knowledge about the details of the project. Their information base graduallyimproves as the project progresses through different phases. After the completion of every phase,the project managers can plan each subsequent phase more accurately and with increasing levelsofconfidence. SoftwareProjectManagementPlan(SPMP) Once project planning is complete, project managers document their plans in a Software ProjectManagement Plan (SPMP) document. The SPMP document should discuss a list of differentitems that have been discussed below. This list can be used as a possible organization of theSPMP document.
