Knowledge gap

A missing, inaccessible, outdated, unclear, or unverified piece of knowledge that prevents a person or AI system from answering a real question reliably.

Business example

Several employees ask how to request remote-work equipment. No approved source answers the question, so operations owns a knowledge gap until the onboarding handbook is updated and the questions are retested.

How it works

  1. 1.Capture a real unanswered, low-confidence, unsupported, or negatively rated question.
  2. 2.Group wording variants while preserving the original user context.
  3. 3.Diagnose whether the cause is missing content, stale content, retrieval, permissions, ambiguity, or an undocumented exception.
  4. 4.Assign an owner, priority, due date, and smallest authoritative source change.
  5. 5.Retest the original question with representative permissions and close the gap with evidence.

Common misconceptions

Every unanswered question means a new document is required.
The source may already exist but be disconnected, stale, poorly retrieved, or hidden by an incorrect access rule.
A gap is closed as soon as someone writes an answer.
The answer must be placed in the authoritative source and retested so the intended user can retrieve supported, current information.
