A couple days ago, an IT lead at a multi-brand retail company was walking us through his environment when the conversation turned to a person, not a system. There's a long-tenured employee who handles the price book, shelf layouts, product design, and helps roll out IT projects, all at once. "She's got all this tribal knowledge," he said, "and if we lose this person, it's going to be a setback for the company." If that describes someone at your business, this one's for you.
Tribal knowledge is a real liability, not just a soft concern
Most small and mid-sized businesses have at least one person like this. They've been there forever, they know how everything works, and none of it is written down. Everyone leans on them because it's faster than figuring it out. That works right up until they take a long vacation, burn out, or leave. Then the company discovers how much was living in one person's head.
This same company had already felt a version of this pain. When their current IT lead started, the previous person handed over the keys with almost no documentation, and still doesn't like taking calls. That's the cost of undocumented knowledge showing up after the fact.
Some people know everything and have everything. If they leave, nobody's going to know how to do their work.
Why "just write it all down" rarely happens
The standard advice is to document processes. Sound advice, but it almost never gets done, because the people with the knowledge are also the most overworked. Asking a stretched employee to stop and write comprehensive documentation is asking for the thing they have the least time for. So the risk just sits on the books.
Where AI can lower the barrier
This is a spot where tools like Microsoft Copilot and other AI assistants can genuinely help, not by magically replacing the person, but by reducing the effort to capture what they know. A few practical uses:
- Draft the scaffolding. AI can generate a first-pass outline of a process document from a short description or a recorded walkthrough, so the expert edits and corrects instead of starting from a blank page.
- Turn conversations into notes. Meeting transcripts and recorded explanations can be summarized into structured documentation, capturing knowledge as it's shared rather than in a separate sit-down session.
- Answer from what's already there. Once documentation lives in SharePoint, Copilot can help people find answers in it, which reduces how often they interrupt the one person who knows.
AI can build structure and capture what gets said, but it can't invent knowledge nobody has written or spoken. It lowers the effort to document, it doesn't remove the need for the expert's input entirely.
The structure has to come first
None of this works if there's nowhere to put the output. That's why a well-organized SharePoint home for documentation matters, one where each department has a clear place for its processes and the right people have access. On this call, the IT lead had already started building exactly that kind of site. The AI piece sits on top of good structure, not instead of it.
Worth adding: this is bigger than IT. On this call, one side of the business documented tightly because it had to manage stores to budget, while another side ran well but had almost nothing written down. Capturing knowledge is an organization-wide effort, and it usually needs the leaders of each area involved, not just the IT person.
If you've got a person like this
If there's someone at your company whose departure would genuinely set you back, it's worth thinking through how to start capturing what they know before you're forced to. We're glad to talk through practical, low-effort ways to do it using the Microsoft tools you probably already pay for.
