Lessons Learned
Insights gathered from past projects, incidents, or deviations and turned into usable knowledge.
What it means
Lessons learned capture not just what happened, but why, and what decision would be made differently next time. Without that reasoning, it's just a log of events.
Why it matters
Lessons are the cheapest form of learning. A lesson that isn't recorded gets paid for again.
A real-world example
After an unplanned shutdown, a record is created that captures the cause, the decision-making process, and a recommended change to the procedure.
Systematically turning one's own experience into knowledge usable in the future.
The systematic improvement of processes based on experience and data from operations.
A proven approach that consistently delivers the best results in a given organization.
Preserved knowledge, decisions, and their context, accessible across the organization and over time.
Systematically finding and eliminating the root cause of a problem.
