• It's good to remember the PMBOK® Process Groups for reflecting the purposes of typical project management (sub) processes: The set of process groups includes the (linear and ideal) structure of "init", "plan", "execute" and "close" accompanied by the concurrent over-all-process "monitor and control". The structure of the classification by process groups is offered by myPmps in form of a seqential survey.

• The PMBOK® Process Groups collect project management processes which also belong to different Knowledge Areas. Hence the PMI® and his PMBOK® offers a cross classification for each project management process. The structure of the classification by knowledge areas is offered by myPmps in form a Conceptual Survey.

(V) Project Management Process Groups

The Process Groups are clusters of different project management processes: Each project management process is not only member of a knowledge area but fullfills also a more general purpose. Therefore these processes can be grouped by their knowledge areas or by  their more general purposes:

Initiating Process Group

The Initiating Process Group "... consists of those processes that facilitate the formal authorization to start a new project or a project phase". The main task of the processes is the generation of "clear descriptions of the project objectives ... including the reasons why a specific project is the best alternative solution to satisfy the requirements". These preliminary words contain also "a basic description of the project scope, the deliverables, project duration, and a forcast of the resources for the organization's investment analysis".

(comp. PMBOK3, page 43)

Planning Process Groupy

The Planning Process Group consists of those processes, by which the multiple aspects of the project management are planned. To make a long story short: "the planning processes develop the project management plan".

(comp. PMBOK3, page 46).

Executing Process Group

The Executing Process Group "... consits of those processes used to complete the work defined in the project management plan to accomplish the project's requirements"

(comp. PMBOK, page 55)

Monitoring And Controling Process Group

The Monitoring And Controling Process Group "... consists of those processes performed to observe project execution so that potential problems can be identified in a timely manner and corrective action be taken, when necessary, to control the execution of the project":

"They key benefit of this process group is that project performance is observed and measured regularly to identify variances from the project management plan."

(comp. PMBOK3, page 59)

Closing Process Group

The Closing Process Group constists of those processes "... used to formally terminate all activities of a project or a project phase, hand off the completed product to others or close a cancelled project".
