Project Life Cycle

The ordered progression of phases a project moves through, from its beginning to its end.

Key Points

  • Structures the project into distinct phases that may be sequential or overlapping.
  • Phase names and counts vary by organization and industry (e.g., concept, planning, execution, closure).
  • Includes governance checkpoints (phase gates) for go/no-go or continue decisions between phases.
  • Different from process groups; the process groups can repeat within each life cycle phase.

Example

An engineering firm uses a four-phase life cycle: concept, design, build, and closeout. After design, a phase-gate review checks drawings, budget, and risks to authorize moving into construction.
