lessons learned

Every project I've worked on has had a "lessons learned" session.

Almost every one produced a document. Far fewer changed anything.

I've seen projects identify the same issues repeatedly:

• Scope creep
• Poor stakeholder engagement
• Weak risk management
• Unclear decision ownership

Then the next project starts and repeats the same mistakes.

So I'm curious:

Does your organisation actually use lessons learned from previous projects?

If not, what's the biggest barrier?

• Nobody can find them?
• Nobody reads them?
• Different teams think their situation is unique?
• Leadership doesn't enforce the changes?

And if you've seen lessons learned work well, what made the difference?
