There is no substitute for the expertise of experts, but how can we share it effectively?

Concrete and completely fictional case: You are the founder and director of BrouetteCorp, Limousin leader in the connected three-wheeled wheelbarrow market.
Jean-Philippe, fifty-four years old, has been the in-house expert on one of your key processes for twenty years: rounding the wheels. He set it up, only he knows all the details. He is very efficient, quite helpful although not with everyone. During meetings, he raises problems about the vulcanization of rubber that no one understands, to explain, after half an hour of collective panic, how he has already solved them and is congratulated.
Jean-Philippe is not yet a problem for your organization: he is keeping his goals, production has never been so fast and the wheels are so round.
But what happens if he gets sick? If he leaves the company? Or simply if their commitment decreases?
You have already tried to convince him to formalize its know-how in one (or several) Word documents, in Notion, in Excels, in Powerpoints... Unsuccessful:”no time with production to ensure”,”too complicated to synthesize”...
You gave him an intern, then an assistant, with the secret mission of doing this formalization work. They left, disgusted, because he did not delegate much to them and did not explain anything to them. “Well, here's the manufacturer's documentation... Ah, by the way, it's not up to date, we've customized the product a lot”
You started to suspect that Jean-Philippe had a slight ill will... unless it was a fear of losing his central place in the company if he shared his knowledge?
But then what to do?
