Process groups
Overview
Projects exist within an organization and do not operate as a closed system. They require input data from the organization and beyond, and deliver capabilities back to the organization. The project processes may generate information to improve the management of future projects and organizational process assets.
The PMBOK® Guide describes the nature of project management processes in terms of the integration between the processes, their interactions, and the purposes they serve. Project management processes are grouped into five categories known as Project Management Process Groups (or Process Groups):
Initiating Process Group. Those processes performed to define a new project or a new phase of an

existing project by obtaining authorization to start the project or phase. Within the Initiating processes, the initial scope is defined and initial financial resources are committed. Internal and external stakeholders who will interact and influence the overall outcome of the project are identified.
Planning Process Group. Those processes required to establish the scope of the project, refine the

objectives, and define the course of action required to attain the objectives that the project was undertaken to achieve. The Planning processes develop the project management plan and the project documents that will be used to carry out the project.
Executing Process Group. Those processes performed to complete the work defined in the project

management plan to satisfy the project specifications.
Monitoring and Controlling Process Group. Those processes required to track, review, and regulate

the progress and performance of the project; identify any areas in which changes to the plan are required; and initiate the corresponding changes.
Closing Process Group. Those processes performed to finalize all activities across all Process Groups

to formally close the project or phase.
