“We can know more than we can tell.” Michael Polanyi wrote that in 1966. Sixty years later, it still explains why the hardest enterprise work resists automation.
Process documentation, knowledge management and LLM copilots all attack the tell side of the problem. Write more down. Index it better. Make it conversational. This helps where the knowledge can be articulated. It does not recover what expertise looks like in motion.
Three decisions no manual contains
The adjuster’s four minutes
A senior handler knows which short policy review prevents the appeal three weeks later, and which source takes precedence when systems disagree.
The engineer’s next parameter
A senior analog engineer knows which device parameter to nudge and what the simulator is likely to say before running it.
The account absent from the PO
An order specialist infers the correct account from seven contextual signals when the decisive field appears nowhere on the document.
Each expert can explain fragments after the fact. None can turn twenty years of pattern recognition into a complete rulebook. The knowledge is real because it produces reliable outcomes, not because it is easy to narrate.
Recover the know side
The interface is where tacit knowledge becomes observable. A screen state creates context. An action reveals a decision. A correction exposes the boundary of a rule. The final outcome tells us whether the path was good.
With explicit consent and a clear privacy boundary, those traces can become a training corpus far denser than click logs or finished records. Expert weighting separates excellence from the mean. Verified-outcome reinforcement learning explores beyond imitation. Postcondition checks make the path auditable.
The category is not a chatbot
A chat interface can expose the first output: grounded knowledge a teammate can query. But the deeper product is a model that carries the workflow through the same interfaces, knows where its evidence ends and leaves a record on every action.
No face. No personality. No theatre. The valuable human quality is the judgment.
