Compatibility work
Operating systems, store requirements and SDKs change. The supported-device policy determines how much checking and adaptation is needed.
Production behavior
Crashes, network changes and backend updates can affect a live app. Useful monitoring and reproducible issue reports reduce uncertainty, but do not remove investigation.
Scope and coverage
Separate routine updates, incident response and new features. Define available capacity, support hours and approval for work outside the agreement.
Ownership and predictability
Maintain build documentation and organization-owned accounts. An app that only one person can release carries avoidable handover and recovery work.
