Which of the following are included in phase gate approvals?

During phase gate reviews, lessons learned from the completed phase are often documented and analyzed to improve future phases. Additionally, the budget and schedule are critically reviewed to ensure the project remains viable and on track for subsequent stages before approval to proceed is granted.

Change control boards and committee consulting are involved in ongoing project governance and change management throughout a project lifecycle, not specific components included within phase gate approvals.

Audit trails, retention, and version control are critical for documentation management and compliance throughout the project, but they are not distinct elements specifically included in phase gate approvals.

Cost estimates and resources required are typically developed during project planning and initial approval stages, and while they inform phase gate reviews, the gate itself is focused on reviewing performance and re-validating rather than creating new initial estimates.
