TL;DR: Process groups are when (Initiating → Planning → Executing → Monitoring & Controlling → Closing). Knowledge areas are what (Scope, Schedule, Cost, etc.). A process belongs to both — one group and one area. The exam tests whether you know which processes fall where.
Process groups describe the sequence of work phases in a project:
| Group | Purpose | Key output |
|---|---|---|
| Initiating | Authorize the project or phase | Project Charter, Stakeholder Register |
| Planning | Define scope, schedule, cost, risks, quality, comms, procurement | Project Management Plan + subsidiary plans |
| Executing | Carry out the work defined in the plan | Deliverables, Work Performance Data |
| Monitoring & Controlling | Track, review, and regulate performance | Change Requests, Work Performance Reports |
| Closing | Formally complete the project or phase | Final Product/Service, Lessons Learned |
No — and this is a direct exam trap. Process groups repeat within every phase of a multi-phase project. Each phase is initiated, planned, executed, monitored, and closed. Phases are project-specific (concept phase, design phase, build phase, etc.) and defined by the project life cycle. Process groups are a methodology overlay applied to each phase.
The bank tests this as: "A project has five sequential phases. After completing Phase 1, which process group starts Phase 2?" Answer: Initiating — because every new phase begins with authorization. The trap answer is "Planning" (seems logical) or "Executing" (the work continues).
Knowledge areas represent the technical disciplines a PM manages:
Each knowledge area spans multiple process groups. Scope Management, for example, has processes in Planning (Plan Scope Management, Collect Requirements, Define Scope, Create WBS) and Monitoring & Controlling (Validate Scope, Control Scope) — but none in Initiating.
Initiating — and this one trips up almost everyone. Stakeholder identification happens at the start, not during Planning. The logic: you need to know who your stakeholders are before you can plan how to engage them. The process "Plan Stakeholder Engagement" is in Planning; "Identify Stakeholders" is in Initiating.
The bank's scenario: project charter is signed, feasibility approved. What do you do next? The answer is Identify Stakeholders (Initiating is still in progress). The trap answer is "Develop Project Management Plan" (Planning) — you can't effectively plan before you know who the stakeholders are.
