[[Knowledge management]] requirements. Before selecting a methodology or tool, define what the knowledge system must do. Requirements vary by context, but the questions are consistent: 1. **Discoverability** - can someone find this without asking a person? 2. **Maintainability** - can it stay current without disproportionate effort? 3. **Connectivity** - can it link to adjacent knowledge? 4. **Survivability** - if the tool changes, does the knowledge survive? Plain, portable formats outlast any specific tool - [[File over app]] 5. **Securability** - can the right access boundaries be enforced - who can read, who can edit, which artefact can reach which agent (human or AI)? ^list These map to and extend the [[FAIR principles]] from research data management. Discoverability ↔ Findable, Connectivity ↔ Interoperable, Maintainability extends Reusable. Securability extends Accessible, which in FAIR already requires authenticated and authorised retrieval. Survivability is an additional governance dimension that protects the others through tool change. Requirements drive method selection. Tool choice follows from methodology, not from requirements directly. ^requirements
