Start with repeated questions
Knowledge Base Engineering begins with a source vault, taxonomy, cleaned knowledge engine, and retrieval workflow. The first useful map is not a folder tree; it is a view of the questions people repeatedly need to answer.
For each question, identify the sources, the owner, the audience, the decision supported, and the current uncertainty. This gives a knowledge system a practical reason to exist.
Create retrieval-ready structure
The canonical service method turns approved material into a taxonomy, page map, workflow, or content map. A source becomes more usable when its purpose, review status, connection to an offer, and access conditions are explicit.
This prepares the same knowledge for people, a website, sales handoffs, content production, and later retrieval-assisted AI work without treating any of those outputs as the source of truth.
Keep the knowledge system governed
Inventory what exists, mark the gaps, and decide what can be trusted before building an assistant or search layer. The service guidance makes this source decision a visible early step.
Review the question map as the business changes. New questions may require new sources; obsolete sources should be marked rather than silently reused.
