Process Project Management (Project Life Cycle)
PMBOK v8 Definition
Process Project Management refers to the systematic management of project processes throughout the Project Life Cycle, which is the series of phases that a project passes through from initiation to closure. The Project Life Cycle provides the basic framework for managing the project, regardless of the specific work involved, and includes the processes of initiating, planning, executing, monitoring and controlling, and closing.
Why It Matters for the Exam
The Project Life Cycle and its associated processes are foundational to every PMI exam question, appearing in situational, definitional, and process-flow questions. Understanding the sequence and integration of processes across the life cycle is critical because the exam frequently tests which process group contains specific activities, and how outputs from one process become inputs to another.
Key Points to Remember (for the exam)
- Five Process Groups: Initiating, Planning, Executing, Monitoring and Controlling, Closing, these are the sequential phases of the Project Life Cycle
- Manage Project Execution process: Located in the Executing Process Group (page 11, 16, 21-23, 114), this is where the actual work of the project is performed
- Monitor and Control Project Performance process: Located in the Monitoring and Controlling Process Group (page 11, 16, 17, 26-28), this tracks progress and manages changes
- Manage Project Knowledge process: Located in the Executing Process Group (page 11, 16, 17, 24-26, 123), focuses on using existing knowledge and creating new knowledge
- Key Outputs: Lessons learned register (page 123), work performance data, and work performance information flow between processes
- Common Confusion: The Project Life Cycle is not the same as the Product Life Cycle, the project life cycle ends when the project closes, while the product life cycle continues through operations and disposal
- Management reserves (page 60, 61) are established during planning but used during execution and monitored during monitoring and controlling
Typical PMI Exam Example
A project manager is leading a software development project. During the execution phase, the team encounters an unexpected technical challenge. According to PMBOK v8, which process should the project manager use to ensure the team captures the solution for future projects? → Answer: Manage Project Knowledge process (Executing Process Group), which updates the lessons learned register.
PMI Exam Traps
-
Trap: Confusing Manage Project Execution with Monitor and Control Project Performance
-
Reality: Manage Project Execution is about doing the work (Executing Group); Monitor and Control Project Performance is about checking progress and making adjustments (Monitoring and Controlling Group)
-
Trap: Thinking the Project Life Cycle is linear with no iteration
-
Reality: The life cycle includes feedback loops, especially between Monitoring and Controlling and Planning (e.g., Monitor and Control Schedule process, page 49, 53-55, feeds back into schedule management)
-
Trap: Believing lessons learned are only collected at project closure
-
Reality: Lessons learned register is updated throughout the project, particularly in Manage Project Knowledge process (page 123)
-
Trap: Confusing management reserves with contingency reserves
-
Reality: Management reserves (page 60, 61) are for unknown-unknowns and require management approval; contingency reserves are for known-risks
Important PMI Connections
| Related Concept | Relationship Type | Exam Attention Point |
|---|---|---|
| Manage Project Execution process | Core process in Executing Group | Produces work performance data used in Monitor and Control processes |
| Monitor and Control Project Performance process | Core process in Monitoring & Controlling Group | Receives work performance data; outputs change requests and work performance reports |
| Manage Project Knowledge process | Supporting process in Executing Group | Updates lessons learned register; feeds organizational process assets |
| Monitor and Control Schedule process | Specific monitoring process | Uses schedule compression, critical path method, and variance analysis to track schedule performance |
Quick Review Questions
-
In which Process Group does the Manage Project Execution process belong, and what is its primary purpose?
-
What is the difference between work performance data produced during execution and work performance information produced during monitoring and controlling?
-
When during the Project Life Cycle should the lessons learned register be updated?
-
Which process in the Monitoring and Controlling Process Group is responsible for tracking overall project performance against the project management plan?
-
How do management reserves differ from contingency reserves in terms of when they are used and who authorizes their release?
