Choose a small group that represents the real roles using the app. Give them specific tasks with realistic data, including an interrupted submission, a repeated click and an account without permission.
Record issues with the role, steps, expected result and actual result. Separate data loss or access errors from cosmetic problems. Agree what must be fixed before wider access.
Prepare a backup and a rollback plan. Once live, monitor application errors and support requests. A release is complete when the team can operate the product, not when the deployment finishes.
