Phase Gates, also known as stage gates or decision gates, are formal checkpoints in a project or process lifecycle where key deliverables and achievements are reviewed against predetermined criteria to determine whether to proceed to the next phase. They serve as critical control points that ensure quality, manage risk, and maintain strategic alignment throughout the project lifecycle.
Phase gates represent structured decision-making points where stakeholders evaluate progress, assess risks, and make go/no-go decisions based on established criteria. They differ from milestones by requiring formal approval and potentially stopping or redirecting the project based on assessment outcomes.
Key characteristics of effective phase gates include:
- Clear decision criteria
- Formal review process
- Stakeholder involvement
- Quality standards
- Risk assessment
- Resource evaluation
- Performance metrics
- Go/no-go decisions
