Definitely if the lessons learnt is just a photocopy or copy-paste process in all projects (i.e. just a formality), it clearly shows that the document is being filled for acquiring or sustaining a certification and not in real sense of improvement in the organization.

In practice, this commonly-performed, typically final, step in the project management life cycle too often fails to provide its potential value because the lessons learned aren’t actually learned and thus aren’t applied. Consequently, in my experience, most organizations’ post-implementation review lessons learned could be produced on a photocopier. That is, because the improvements are never implemented, post-implementation reviews tend to produce the same lessons learned project after project.
