- Definition
- Current, organised information that enables people to understand, operate, verify and evolve the system.
- Nuance
- The presence of files is not enough; documentation must be findable, versioned, connected to reality and tested by its reader.
- Concrete situation
- A recovery guide states prerequisites, decisions, commands, positive checks and expected failures, then another person runs it.
- Associated terms
- Memory, decision, version, operations, recovery.
- Avoid
- Saying “it is documented” because code or a folder exists; a document with no owner or date.
