Tribal knowledge is everything your business knows that no document does.
It is which supplier actually picks up the phone. Why the schedule gets built around Thursday deliveries. How to quote the jobs that do not fit the price sheet. Which machine needs a second look when it makes that one sound.
In most shops, all of it lives in the same place: the head of your most experienced person. The stuff only Dale knows.
Why it never makes it into the manual
Documentation was never anyone’s job. Dale was hired to run the floor, not to write about running it. Every hour spent writing is an hour off production, so the writing never happens.
The knowledge is invisible to the person holding it. After twenty years, judgment feels like common sense. Dale does not know that he knows things, so it never occurs to him that anyone would need them written down.
The binder freezes, the operation moves. Even when someone documents a process, the operation keeps evolving and the binder does not. Within a few years the documentation describes a business that no longer exists, and the real answers go back to living in heads.
None of this is negligence. It is the natural result of a business that rewarded getting work done over recording how. The cost only becomes visible when the person carrying it gives notice, and by then the options are thin.
Three first steps you can run this month
- List the questions only one person can answer. Sit down with your leads and write every question that has a single human answer key: quoting judgment, scheduling logic, machine quirks, supplier handling. This list is your risk register. Most operations are surprised by how long it gets.
- Record the walkthroughs. Have your senior people talk through their work on camera or voice memo while they do it. Do not aim for polish; aim for capture. An hour of Dale explaining how he reads a spec is worth more than a binder nobody will write, and it costs one hour.
- Pick the one process that hurts most when they are away. Vacations are your preview of retirement. Whatever waited last time Dale took two weeks off, that process goes first. Capturing one process well beats capturing ten badly, and it gives you proof before you go wider.
From captured to usable
Recordings and lists stop the knowledge from leaving. They do not yet make it useful, because a folder of videos is still a digging exercise.
The step after capture is a searchable knowledge system: a private system where a new hire types a question the way they would ask it out loud and gets the answer your veteran would give. That is the difference between stored and usable. At Trinity Door Systems, making two decades of expertise searchable compressed a 7-year apprenticeship into 90 days, with every existing system left in place.
We wrote about what that looks like from the inside in Twenty Years of Know-How Just Walked Out the Door.
If your list from step one has more than five questions on it, that is your sign. Book a 30-minute ops walkthrough and we will show you how a knowledge system captures the rest: nexxtideas.com/contact
