Knowledge capture: when it is useful
Knowledge capture takes what people know and only ever tell each other verbally, and puts it somewhere a new starter and a system can both read. The sources are support threads, handover notes, supplier quirks and the answers senior staff repeat weekly. It is the least glamorous pattern and often the highest leverage.
( The Detail )
What the pattern does
The decision it improves is anything that currently waits on one person. When the answers exist in writing, work can be handed to a junior, an assistant or an AI tool without a quality drop, and the organisation stops paying an interruption cost every time a routine question comes up.
Looked at from this angle
A pattern earns its place when a decision is being made repeatedly on poor information, or when the same assembly work is redone by hand every period. If the decision is rare, or the current answer is already good enough, the pattern is interesting rather than useful and can safely wait.
The honest test is what changes once it exists. If you cannot name the meeting, the order, the roster or the pricing call that would go differently, the output will be admired once and never opened again. Usefulness is a claim about behaviour, not a claim about data quality.
How to approach it
Begin with the decision rather than the tool. Name the recurring judgement this affects, the information it depends on, and the person accountable for acting on the result. That framing keeps the first build small enough to inspect and useful enough to matter.
Keep a human review point in the loop until the quality and the failure modes are understood. A system that shows its working - what it drew on, where it is uncertain, and what it deliberately left alone - is one a business can keep running after the initial build.

Start small enough to review, but on a workflow important enough to show whether a better system is worth building.
