"Knowledge has to be improved, challenged, and increased constantly, or it vanishes."
Peter Drucker

Every company has one. It launched with a name, an announcement, and a champion. Six months later it is a graveyard with a search bar. You know yours by the date on its last edit.

Here is why wikis die, and it is not the software. Knowledge stored is knowledge unemployed. It sits in the building, fully qualified, waiting for someone to come and ask it something. Almost nobody does, because reference material is where you go when you already know a thing exists. The wiki's fatal flaw is that it waits.

A brain differs from a wiki in exactly one way: it works. It has a job description. Ours reviews and coaches OKRs. Ask it whether a Key Result is any good and it answers in our doctrine, with our standards, at any hour, without waiting to be browsed. Knowledge with a job shows up where the work happens. Knowledge without one waits politely until the licence renewal lapses.

The job is also what keeps it alive. A system doing daily work gets corrected daily. Wrong answers surface, gaps get filled, the feeding loop runs itself. Nobody proofreads a museum.

So the build rule is the hiring rule. Do not attempt the everything-wiki; that is how the graveyard got its plots. Pick one job: the question your teams ask most, or the work eating your most senior hours. Build the smallest brain that can hold that job. The raw material already exists in your decks, docs and post-mortems, unassembled rather than absent, so this is days of work, not quarters.

Give it a job.

Our brain got promoted this fortnight. Job one was coaching OKRs. Job two is drafting our marketing: it now reads four customer persona files and a bank of house lines before it writes a word, in our voice instead of the average's. Full disclosure, and you may check the style for yourself: the issue you are reading went through the system it describes, with me, Matt, in the loop, making tweaks and keeping it true to what we know and believe.

Open your wiki and find the date of the last edit. Then ask the only question that revives it: if this knowledge applied for work tomorrow, what is the one job we would hire it to do?

Give it a job.

See you in a fortnight,
Matt

P.S. Job one is free to take home. The AI OKR Coach kit is our brain's first job description, packaged. Build it into your own LLM tonight, then forward this to whoever owns your graveyard.
