How often should you revalidate captured knowledge?
There is no single right interval. Review captured knowledge on a rhythm that matches the risk — more often for knowledge behind safety, quality, customers or money, less often for stable routine — and add triggers that force a review straight away: a changed customer agreement, a new system, an incident, or an answer that turned out to be wrong. A real review checks the knowledge against how the work is done today, not just that a document still exists.
Before you start
Prerequisites: an overview of the knowledge you captured — processes, task cards, decision rules — an owner for each item, and a way to record when something was last confirmed and by whom.
Use this guide as soon as you have captured knowledge people rely on — not a year later. The moment people start working from captured knowledge is the moment an outdated version starts doing damage. Signs you are late: people keep checking with the expert anyway, or two versions of the same instruction are in use.
The steps
Step 1 — Sort the knowledge by risk
Group items by what goes wrong if they are out of date: safety or compliance, customer impact, money, or internal efficiency. The higher the impact, the shorter the review rhythm.
Pitfall: One interval for everything. Reviewing trivial items as often as critical ones wears reviewers out, and they stop doing both.
Step 2 — Set a rhythm per risk group
Agree a review rhythm for each group and put it in the owner's calendar. Critical knowledge deserves a review at least once a year, and more often when it changes frequently.
Pitfall: Rhythms nobody owns. A review date without a named person is a date that passes.
Step 3 — Define the triggers
Agree the events that force a review now: a new or changed system, a changed customer or supplier agreement, an incident, complaint or audit finding, a person leaving or joining, and any answer that turned out to be wrong.
Pitfall: Waiting for the scheduled review after a change. The knowledge is wrong from the day of the change.
Step 4 — Review against real work
Take a recent case and check the knowledge against what actually happened. Ask the people who did the work what was missing, outdated or wrong.
Pitfall: Checking that the document still exists. Existence is not accuracy.
Step 5 — Record the outcome with a date
Confirm, correct or retire each item, and record who confirmed it and when. Keep earlier versions with their dates instead of overwriting them.
Pitfall: Silent edits. Without dates and history, nobody can tell which version a past decision relied on.
Step 6 — Tell the people who use it
When knowledge changes, tell the people who rely on it, and check that a colleague can still do the task with the new version.
Pitfall: Updating the knowledge without telling anyone. The old habit wins.
An example
Take a food producer that has captured the knowledge behind its production and packaging. It sorts that knowledge into three groups: allergen handling and cleaning as critical, customer-specific packaging rules as customer impact, and internal reporting as efficiency.
The allergen procedures are checked every quarter against a real production run, by the quality lead and an operator from the line. The packaging rules are reviewed twice a year — and at once when a customer changes its specification. Internal reporting is reviewed once a year.
When a new labelling machine arrives, every task card that mentions labelling is flagged for review that same week, not at the next scheduled date. The operators test the updated cards on the first run with the new machine, and the old versions stay available with their dates.
Where MentX comes in
MentX captures how your company really works: the knowledge of your key people and the processes they run. We offer both a hands-on service approach — mapping your processes and capturing the knowledge behind them, from meetings, workshops and a guided intake — and our own personality-aware knowledge base, with full source attribution, in your own Knowledge Space. We build on the tools you already use and add best-practice solutions where they fit.
In the MentX knowledge base, every statement keeps its source and its date, and new knowledge invalidates the old instead of overwriting it — that is what a temporal knowledge graph does. Owners and review triggers are agreed when you capture your operations.
Checklist
- Knowledge grouped by risk
- A review rhythm per group, owned by a named person
- Triggers that force an immediate review
- Reviews checked against a recent real case
- Outcomes recorded with who and when; history kept
- Users told, and the task re-tested after a change
Questions people ask
Who should do the review?
The owner of the knowledge, together with at least one person who uses it in their work. The owner confirms what was intended; the user confirms what really happens.
What if nobody has time for reviews?
Start with the critical group only and let the triggers do the rest. A small review that happens is worth more than a complete one that is planned and skipped.
