According to the PMBOK® Guide and the Standard for Project Management, the process of defining, preparing, and coordinating all subsidiary plans and integrating them into a comprehensive project management plan is Develop Project Management Plan.
As per PMI standards, this process is part of the Project Integration Management Knowledge Area and occurs within the Planning Process Group. The Project Management Plan is the primary document used to manage the project. Key characteristics of this process include:
Integration: It consolidates all subsidiary management plans (e.g., Scope, Schedule, Cost, Quality, Resource, Communications, Risk, Procurement, and Stakeholder Management Plans) and baselines (Scope, Schedule, and Cost baselines) into a unified whole.
Consolidation: It defines how the project is executed, monitored, controlled, and closed.
Baselines: It establishes the performance measurement baselines against which project execution will be measured.
Updates: The Project Management Plan is a " living document " that is updated and revised through the Perform Integrated Change Control process as the project progresses.
The other options are incorrect based on the following PMI process definitions:
Direct and Manage Project Work: This is an Executing process. It involves leading and performing the work defined in the project management plan and implementing approved changes to achieve the project ' s objectives.
Plan Quality Management: This is a Planning process, but it is a " subsidiary " process. It focuses specifically on identifying quality requirements and standards; its output (the Quality Management Plan) is an input to the Develop Project Management Plan process.
Monitor and Control Project Work: This is a Monitoring and Controlling process. It involves tracking, reviewing, and reporting the overall progress to meet the performance objectives defined in the project management plan.
As per the PMI Lexicon of Project Management Terms, the Develop Project Management Plan process ensures that all aspects of the project are aligned and that the project manager has a clear, integrated roadmap for success.
