PMBOK (Project Management body of Knowledge) recognizes 5 basic process groups – Initiating, Planning, Executing, Monitoring and Controlling, Closing. Processes overlap and interact throughout a project or phase.
Initiation – Initiation process group consists of the processes that facilitate the formal authorization to start a new project or a project phase. To Define and authorize new project.
Initiation Process Group –consists of processes that facilitate the formal authorization to start a new project or project phase.
Planning Process group involves coordinating people and resources and to develop project management plan. It is constituent process and interactions to plan and manage a successful project. It helps gather information from sources. Planning Process Group facilitates planning across multiple processes, it decides if they need to be done and by whom. (develop project management plan -> Scope planning-> Scope definition -> Create WBS-> Activity definition -> Activity Sequencing-> Activity Sequencing -> Activity Resource Estimating -> Activity Duration Estimating -> Shdule Development -> Cost Estimation – Cost Budgeting-> Quality Planning -> Human Resource Planning-> Communication planning -> Risk Management planning -> Risk Identification -> Quality Risk Analysis ->Quality Risk Analysis ->Risk Process Planning-> Purchase and Acquisitions -> Plan Contracting).
Executive process group is used to complete the work defined in the project management plan to accomplish project’s requirements. It includes following project management processes: Direct and Manage Project Execution ->Perform Quality Asurance->Acquire Project Team -> Develop Project Team -> Information Distribution -> Request Seller Responses -> Select Sellers
Monitoring and Controlling – consists processes preformed to observe project execution so that potential problems can be identified in a timely manner and corrective action can be taken, when necessary, to control the execution of the project. It monitors and controls work being done, entire project effort, provides feedbacks between project phases, in order to implement corrective or preventive actions to bring the project compliance with the project management plan. (it revised as Pan-do-check-act circle). It includes following management processes: Monitor and Control Project Work->Integrate Change Control ->Integrated Change Control->Scope Verification->Scope Control->Schedule Control -> Const Control -> Perform Quality Control -> Mange Project Team ->Performance Reporting -> Manage Stakeholders -> Risk Monitoring and Control -> Contract Administration.
