Plan day-to-day operation by checking account ownership, user training, backup restoration and support scope at software handover.
Going live does not prove the business can operate the software independently. Handover should cover technical access and daily tasks together.
Verify account ownership
Record who controls domains, hosting and external services. Assign permissions by role and check agreed source-code and documentation delivery separately.
Train through real tasks
Have users create records, correct mistakes and perform their normal responsibilities. Watching a demonstration may not be enough. Provide concise reference instructions.
Test restoration
Having a backup is different from being able to restore it. Verify the process in a test environment and identify its owner, coverage and frequency.
Define support boundaries
Separate defect reporting, maintenance and feature requests. Agree on communication and prioritisation, then record outstanding items and acceptance status at handover.
