008THE GRAVEYARD
When a Company Wiki Becomes a Graveyard, Fix the Clock
A record of a machine rattle is only a starting point. Knowledge escrow proposes capture during work, preparation when needed and supervised rehearsal; access, sources and current context still govern what can be used.
Preparation can come before anyone knows the question
A technician asked to document for an unknown successor must choose what context to preserve before the need is clear. That timing can waste effort. It is one reuse problem, not an explanation for every neglected wiki. Authors may reuse their own records, help peers or have immediate reasons to document. Permissions, maintenance and support also matter.
WHAT WON'T COME OUT
We can know more than we can tell.
Michael Polanyi, The Structure of Tacit-Knowing, Duke lecture, 1964, p. 12; excerpt
In the lecture, Polanyi describes recognizing faces and learning through advice, example and trial and error (pp. 11–15). Tacit knowing involves integrating particulars; listing them does not reproduce that skill. The rattle record may help someone learn without containing everything the technician knows.
CAPTURE IN THE WORK
Keep the incident attached to its evidence
In this example, a technician notices a rattle change under load. Preserve the account beside the job record, decision, correction and observed outcome. Record who supplied it, when, which operating conditions it covers and who may see it. This is not free capture, and it will not extract every tacit distinction. It gives a later reader something to inspect and question.
MOVE THE COST
Prepare for the question. Withhold what it cannot support.
A real question triggers preparation from sources the asker is allowed to use. Release only claims whose provenance, current applicability and access scope are established. Keep citations and visible redactions with the extract. Missing access, sources or freshness blocks the unsupported answer: the archive cannot support this answer yet. Knowledge escrow is this proposed timing arrangement, not a demonstrated reduction in total effort.
THE REUSE WORK
Someone still has to make the record usable
M. Lynne Markus's 2001 theory of knowledge reuse distinguishes producers, intermediaries and consumers; one person may occupy all three roles (pp. 60–62). Reuse needs differ with the recipient and purpose. Retrieval, interpretation and restoring context require effort; incentives alone may not solve access and support problems (pp. 82–83, 87–88). A model may assist preparation, but this paper does not establish that an AI archive performs these jobs reliably.
THREE ASKERS
The same incident supports different permitted extracts
- Stand-in: operating evidence for the rattle question
- Buyer's adviser: an incident trail within diligence access
- New hire: material for supervised practice
Keep the underlying record intact. Each question gets a scoped extract with its source connection, omissions and currency limits. Redaction must not expose restricted material merely to prove provenance. If removing context leaves a claim unsupported, withhold it. An available record does not imply that every asker may receive it.
THE REHEARSAL
Record the missed cue before the correction
Use a controlled training rig and agree the expected stop or escalation condition before the trial. In this example, the stand-in misses the change in rattle under load. Record the miss and the missing context before the expert amends the account. Try again without expert prompting, with the archive available, and record what the stand-in does before offering help. A correction is not a demonstrated improvement, and one successful trial would cover only the tested condition.
THE STAND-IN TEST
Can the next person use it and recognize its limits?
- Choose one exception and preserve its evidence
- Ask a permitted question and check the proposed answer
- Rehearse, record the gap, amend and try again
Keep the rule, owner and scenario attached to the tested condition. Record what happened, what remains unknown and when the evidence needs review. A passed trial informs that handoff; it does not certify general competence or make later learning unnecessary.
