The Project Life Cycle is the series of phases that a project passes through from its start to its completion. Each phase represents a logical grouping of activities that contribute to the delivery of the project’s objectives, including initiation, planning, execution, and closing.
It provides a structured path for managing work, allocating resources, and applying controls throughout the life of the project.
Key Characteristics
- Phase-Based Structure – Divides the project into manageable segments
- Sequential or Overlapping – Can follow linear, iterative, or hybrid models
- Aligned with Deliverables – Each phase culminates in specific outputs or milestones
- Supports Control and Oversight – Facilitates checkpoints, reviews, and decision gates
Example Scenarios
- A construction project moves through design, permitting, building, and inspection phases
- A technology project follows initiation, planning, development, testing, and launch
- An event planning effort proceeds from concept to logistics, delivery, and post-event wrap-up

Role in Project Delivery
- Organizes Work – Breaks down large efforts into logical steps
- Enables Tracking and Control – Provides milestones for assessing progress
- Improves Forecasting – Clarifies scope, time, and resource requirements at each stage
- Supports Governance – Aligns with reviews, approvals, and quality checks
