According to the PMBOKGuide (Project Management Body of Knowledge), specifically in the chapters covering Project Management Processes, the core purpose of these processes is to manage the project ' s progression:
* Effective Flow (Option D): PMI defines project management as the application of knowledge, skills, tools, and techniques to project activities to meet project requirements. This application is accomplished through the effective integration of the project management processes. The processes are grouped into Process Groups (Initiating, Planning, Executing, Monitoring and Controlling, and Closing) specifically to ensure the effective flow of the project throughout its life cycle. This ensures that the transition between phases is structured and that the project moves logically from a concept to a finalized result.
* Efficient Means (Option B): While processes certainly aim for efficiency, the primary definition provided by PMI focuses on the flow and integration of the project rather than just being a " means " to an objective.
* Alignment with Strategy (Option A): This is primarily the function of Portfolio Management and the Project Charter. While project management supports this, the processes themselves are the mechanical engine that moves the project forward.
* Performance of the Team (Option C): This is managed through the Project Resource Management knowledge area (specifically the " Develop Team " and " Manage Team " processes), but it is only one aspect of the overall project management process framework.
In the PMI framework, the Project Management Processes are iterative and linked by the outputs they produce. The output of one process generally becomes an input to another process or is a deliverable of the project, creating the " flow " necessary for project success.
