  1. 1Summarise in five sentences. What happened, the potential outcome, what you found, what changes and how many actions are done.
  2. 2Be honest about both sides. List what went well — so it is kept — and what did not, without naming people as the cause.
  3. 3Copy actions from the analysis. Same IDs, owners and due dates as the root cause analysis, with today's status and anything overdue.
  4. 4Send the close-out note. Everyone involved and every team doing the same work gets the short note; leadership gets the full document to sign.

The situation

When this template earns its place

The investigation is done and the actions are under way. The people who were involved, the witnesses and the teams who do the same work need to hear the outcome — otherwise the next incident starts the same way. This live document opens on the page without registration and ends with a short close-out note you can send to everyone involved.

Common mistakes

What makes the document stop working

A report that only goes to management

The people who do the work are the ones who need the lesson. Send the close-out note to them first.

Lessons with no change

"Be more careful" is not a lesson. Each lesson should point to a changed procedure, check or design.

Actions that drift from the analysis

If the owners or dates differ from the root cause analysis, nobody knows which is right. Copy them, and say which are overdue.

FAQ

Questions before you use it

Is it free? Do I need to sign up?

It is free and you do not need an account to fill in the document or to send the close-out note. Sign-in appears only when you save it to a workspace or invite your team.

Who should receive a lessons learned report?

Everyone directly involved, the witnesses, teams who do the same work, and the managers who approve the procedure changes. The short note is for most people; the full document is for those who sign.

What is the difference between lessons learned and a post mortem?

A post mortem usually means the analysis itself, often for IT incidents or projects. Lessons learned is the summary you share afterwards: what changes and why.

When should we hold the lessons learned review?

After the root cause is agreed and the first actions are under way, while people still remember the details. Many teams do it within a few weeks.

Should the report name the people involved?

Name people where it helps, such as action owners. Do not present a person as the root cause; describe the conditions that made the mistake possible.
