Usability checks
Test a complete task from entry to confirmation, including missing or invalid input. Screen-by-screen visual approval does not test the workflow. Confirm that forms, phone links, and replies reach the right person.
Handle duplicate requests, edits, permissions, and audit needs. Confirm how records are recovered after a failed operation. Separate a measurement error from a change in customer behavior.
