The 5 phases of the project management life cycle
Initiation, planning, execution, monitoring and closure — the five phases explained.
The project life cycle consists of five sequential phases that guide managers from inception to completion. Understanding them improves communication, keeps goals realistic and helps mitigate risk.
1. Initiation
Establish the foundation: define scope, costs and resources; identify stakeholders; run feasibility studies; and produce a Project Initiation Document (PID) or Statement of Work (SoW).
2. Planning
Build the roadmap: set timelines, break work into tasks, assemble teams, allocate budgets, identify risks and hold a kickoff — ensuring each objective is achievable in the allocated time.
3. Execution
Turn plans into action: recruit resources, delegate tasks and coordinate the team, providing clear task definitions, managing expectations and communicating consistently.
4. Monitoring
Track progress against the plan: review timesheets and deliverables against acceptance criteria, manage quality and risk, and apply corrective adjustments when deviations occur.
5. Closure
Confirm requirements are met and formally close: deliver the finished product, release the team, run a retrospective and document lessons learned.
