Project Management: Project Plan (Definitions)

"A formal, approved document used to guide both project execution and project control." (Timothy J  Kloppenborg et al, "Project Leadership", 2003)

"A document that identifies project tasks, and describes how an organization intends to perform and control these tasks. The plan typically describes the tasks, the schedule, the production and management processes, the resources required, organization and responsibilities of the participants, and potential risks. For large projects, project plan(s) are usually split into several separate plans covering development, configuration management, quality assurance, risk management, and so forth." (Richard D Stutzke, "Estimating Software-Intensive Systems: Projects, Products, and Processes", 2005)

"A plan that provides the basis for performing and controlling the project’s activities, which addresses the commitments to the project’s customer." (Sandy Shrum et al, "CMMI: Guidelines for Process Integration and Product Improvement, Second Edition", 2006)

"The project plan consists of one or several planning documents (e.g., work breakdown structure, schedule, resource planning) that define the project scope and essential project attributes. It may also consist of a directory structure with different files. The project plan is the basis for project control. If the project plan consists of several planning documents, care must be taken that, in sum, the individual documents represent a conclusive, coherent whole."
