Protocol
Update durable knowledge when it is used and challenged
Use creates both value and the best opportunity to detect staleness.
When it fits
- A note is reviewed on a calendar even when nobody uses it, while frequently used notes can still stay wrong.
When to avoid it
- Some safety, compliance or expiring information needs time-based review regardless of use; keep those explicit exceptions.
Why it matters
When an important note is used for a real task or decision, check whether its source, scope and state are still adequate. If new evidence challenges it, update or supersede it and preserve the reason. Add a scheduled review only where time-sensitive risk justifies one.
Steps
- Current use triggered a staleness check.
- Source status checked where material.
- Scope still matches use.
- Contradictory evidence reconciled.
- State updated or superseded if needed.
- Scheduled review reserved for genuinely time-sensitive knowledge.
An example
A deployment checklist is checked and updated when used after a platform change instead of receiving meaningless monthly reviews when nothing changed.
Check your result
High-use knowledge accumulates maintenance attention where errors would actually matter.
Keep this limit in mind
- Some safety, compliance or expiring information needs time-based review regardless of use; keep those explicit exceptions.

Evidence and sources
Personal information management research frames the job as a lifecycle of acquiring or creating, keeping, organizing, maintaining, finding or re-finding, using and distributing information in support of future needs.
The lifecycle is descriptive and does not prescribe one folder, tagging or note-taking system.
Personal Information Management · Abstract and overview
A 2026 systematic review treats personal information management on desktop and mobile devices as affected by multiple human and technological factors rather than a single organization technique.
Available summary does not justify ranking specific PIM tools or methods.
