In short. For a retirement not to take the know-how away, you must measure before handing over: list the knowledge, count its holders, compute its criticality. Then start from tasks, have experts appointed by their peers, hand over in pairs and verify with a test. For critical know-how, allow twelve to twenty-four months.
The paradox is familiar to every industrial firm. No event is more predictable than a retirement: the date is known years in advance. And yet, in most organisations, the know-how leaves with the person. This is not a problem of goodwill; it is a problem of method.
Why handover schemes fail
- They start too late: three months before the departure there is time for a tour of the workshop, not for handing over fifteen years of craft.
- They target the person, not the knowledge: people are asked to “write down what you know”, a question nobody can answer. An expert does not know what they know.
- They produce documents nobody rereads: a two-hundred-page binder handed over on the last day has never trained anyone.
- They are not prioritised: people try to hand everything over, so nothing is handed over. Out of five hundred knowledge items, about twenty truly deserve a plan.
The four-step method
1. Measure before handing over. List the knowledge items, not the people. For each one: how many holders, at what level, how important for your processes. The crossing gives a criticality, and the criticality gives a short list — the knowledge items a departure would tip into the red zone.
2. Start from tasks, not from memory. Instead of asking the expert what they know, start from what they do: their tasks, their processes, the decisions they make alone. Every task reveals the knowledge it requires. That is the only way to reach tacit knowledge — the kind its holder never thinks of mentioning.
3. Have experts appointed by their peers. Ask everyone: “for this difficulty, who do you call?”. Concordant answers point to the real holders, far better than an org chart. It is also the only method that works in an organisation that is just starting, where no level has been measured yet.
4. Hand over in pairs, and verify. Critical know-how is not handed over by a document: it is handed over by a pair, over time, with experience feedback written along the way and validated by a committee. Then you verify that it went through — with a mastery test, not an attendance signature.
How long before the departure?
For ordinary know-how, three to six months is enough. For critical know-how carried by a single person for fifteen years, count twelve to twenty-four months: the time for the successor to meet, in real situations, the rare cases that make the difference. That is exactly why you must measure early — the measurement says which knowledge items deserve those two years, and they are never many.

Frequently asked questions
How long before retirement should the handover be organised?
Three to six months for ordinary know-how; twelve to twenty-four months for critical know-how held by a single person for fifteen years.
Why doesn't asking the expert to write down what they know work?
Because an expert does not know what they know. Start instead from their tasks, their processes and the decisions they make alone: every task reveals the knowledge it requires.
How do you check that knowledge has really been passed on?
With a mastery test, not an attendance sheet. The lessons learned written along the way are validated by a committee.
