Definition
A scheduled calm state where teams intentionally slow or stop throughput so inspections, upgrades, and rehearsals can happen without crisis pressure. Maintenance windows make stoppability routine instead of reactive.
Each window is negotiated with the people impacted, includes published service guarantees, and documents which safeguards were tested so unfinished work rolls into the shared repair log.
Scope
D. System states & architectures. Operational postures that determine how harm is absorbed—or amplified.
Operational tests
- Evidence appears in documentation, interface cues, or governance artifacts that reflect maintenance window.
- Teams can point to a concrete example that demonstrates maintenance window in practice.
