Lessons Learned Review
A structured project-closeout discussion capturing what went well, what didn't, and what the team would do differently next time, documented for use on future projects rather than left as informal institutional memory that leaves with whoever happened to be on the job.
Why it matters
Institutional memory that only lives in people's heads walks out the door the moment those people move to a different project or a different company, documenting it is what actually lets the next team benefit from what this one learned.
On a real project
A project team holds a lessons learned session at closeout and documents that a specific MEP coordination conflict recurred throughout the job, a finding the next project's team can reference before their own coordination process starts.
Who this matters most to
A Project Manager facilitates the lessons learned review at closeout, turning the team's real experience into a written record the company can actually reuse.
Where this goes wrong
A project team spends weeks untangling a recurring MEP coordination conflict but never holds a formal lessons learned review at closeout to document how it kept happening. The same avoidable coordination conflict recurs on the company's next similar project, costing another few weeks, since nothing was ever documented for the next team to learn from.
