Every specialty chemical company has a version of the same person. They have been there twenty-five years. When an inquiry arrives that nobody else can answer, it goes to them, and they answer it in an hour from memory. They know which grade the customer in Ohio settled on four years ago and why the obvious choice failed.
Industry sources estimate that around a quarter of the chemical manufacturing workforce will be eligible to retire within five years. Very little of what those people know has been written down.
The problem is not that the knowledge is secret. It is that it is unstructured. It lives as pattern recognition built from thousands of inquiries: which specification actually matters for a given application, which product performs better than its data sheet suggests, which customer request is really a different question wearing a disguise. None of that is in the ERP. Some of it is in email threads nobody can find.
The usual response is a documentation project, and the usual outcome is a folder of documents that were accurate the week they were written. Documentation is a snapshot of judgment. It ages, it is not searchable in the way a question is asked, and the person writing it does not know which of their instincts are unusual enough to be worth recording.
A different approach is to capture the judgment as it is exercised. Every inquiry answered is a decision: these were the requirements, these products were eliminated and for what reason, this one was recommended, and this is what the customer eventually bought. Recorded consistently, that becomes a structured record of how the company actually answers questions — built as a by-product of doing the work rather than as a separate project nobody has time for.
It does not replace the person. Nothing replaces the person. But when they retire, the company still has the record of what was recommended, to whom, and why, in a form a newer rep can search.
There is a commercial reason to care, beyond sentiment. A company where three people can answer hard inquiries quickly is a company that responds to three inquiries at a time. When one of those people leaves, response times get worse in a way that is difficult to see and easy to lose deals over. Speed of first useful response is a competitive variable in this industry, and it is quietly tied to a small number of people who will not be there forever.
The window to capture that is while they are still answering the questions.
