Helpdesk knowledge retirement research: 10 tests before removing an article

Methodology and findings

An old article can be dangerous when its scope or action no longer matches the service. Before removal, identify where it is linked, which request types use it, and whether an approved replacement covers the same decision.

Retirement is a knowledge-control decision, not merely a deletion. Record the reason, owner, effective date, replacement route, and treatment of open tickets that still reference the old guidance.

Use customer wording and failed-search evidence to make the replacement findable, but do not preserve obsolete instructions just because they are familiar. Mark boundaries clearly when the new article applies only to a narrower role or system.

Sample search results and recent tickets after the change. The review should check that agents can find the replacement, customers are not sent to a dead end, and the owner can reverse the change if evidence shows harm.
