What shapes the scope of maintenance.

Maintenance plans are sized to the application, not a one-size bundle:

  • Size and age of the codebase

    Older code and outdated libraries need more attention.

  • Platforms covered

    iOS, Android, web app, backend, or all of them.

  • Response expectations

    How quickly issues must be picked up and fixed.

  • Planned improvements

    Small feature work on top of fixes, updates and monitoring.

What to have ready before you start.

A handover is faster with:

  • Access to the code repository and hosting
  • App store and third-party service accounts
  • Any documentation, even if it is out of date
  • A list of known bugs and user complaints
  • Who to contact when something breaks
