What process formally specifies and records the transition between critical stages in the project lifecycle?

The process that formally specifies and records the transition between critical stages in the project lifecycle is known as a project quality gate. Quality gates serve as checkpoints within the project where the progress, quality, and alignment with project objectives are assessed before allowing the project to move to subsequent stages. This ensures that all required standards and criteria are met, facilitating a controlled transition between phases.

Project quality gates are essential for risk management and ensuring that the project is on track and aligned with overall goals. They establish clear criteria that must be satisfied to proceed, promoting accountability and a structured approach to project management. They also help in identifying any potential issues early, thus allowing for timely adjustments to keep the project on course.

The other options, while relevant to project management, focus on different aspects. Project milestones refer to significant events or achievements in a project timeline, project review represents a broader evaluation of the project’s performance without a formal gate function, and project closure pertains to the finalization of the project after all deliverables have been completed, rather than the transition between critical stages.
