The Process Flow

-          Process groups interact and overlap with each other

-          Process groups are iterative and might be revised throughout the project’s life several times as the project is refined

-          Iterative Process – According to the PMBOK Guide, the process of going back through the process groups

-          The conclusion of each process group allows the project manager and stakeholder to reexamine the business needs of the project and determine whether the project is satisfying those needs

Process Interactions

-          Underlying the concept that process groups are iterative is a cycle the PMBOK Guide describes as the Plan-Do-Check-Act cycle, which was originally defined by Walter Shewhart and later modified by Edward Deming à idea behind the concept is that each element in the cycle is results-oriented

-          Project Phases – describes how the work required to produce the product of the project will be completed

-          Project Management Process Groups – organize and describe how the project activities will be completed in order to meet the goals of the project

-          Plan-Do-Check-Act Cycle – an underlying concept that shows the integrative nature of the process groups
