Does the system support client customizations from one release to another?

This question is asking whether your system allows customers to make customizations to the software and whether those customizations are preserved when you release new versions of your software. In a security assessment context, this question matters because customizations can introduce security risks if not properly managed during upgrades. When customers modify your system to meet their specific needs, these modifications could potentially break during updates, be overwritten, or create security vulnerabilities if the upgrade process doesn't properly account for them. The question aims to understand: 1. If your system allows client customizations (like custom fields, workflows, integrations, etc.) 2. How these customizations are handled during version upgrades 3. Whether there's a formal process to ensure customizations remain secure and functional after updates A good answer should explain whether customizations are supported, how they're preserved during updates, what testing is done to ensure compatibility, and what documentation or guidance is provided to customers about maintaining their customizations securely across releases.
