What term describes qualitative information that reflects the learning derived from a process, method, or tool performance?

The term that describes qualitative information reflecting the learning derived from a process, method, or tool performance is "Lessons learned." This concept encompasses insights gained from experiences, including what worked well and what did not, allowing for continuous improvement in future projects or processes. Lessons learned are specifically aimed at capturing knowledge from completed tasks or projects, which can be invaluable for future planning and execution.

In contrast, other terms such as best practices refer to established methods that have proven to be effective, rather than information derived from post-process evaluations. Performance metrics are quantitative measures used to assess efficiency and effectiveness but do not encompass qualitative insights or learning. Feedback analysis involves evaluating responses or input but tends to focus more on specific inputs rather than the broader knowledge and insights gained from experiences. Thus, "Lessons learned" most accurately captures the essence of qualitative learning derived from performance assessments.
