Equipment or systems that fail acceptance testing should be documented against the relevant requirement and assigned for investigation and correction.

The project team should determine whether the failure involves installation, configuration, equipment, infrastructure, integration, or an unclear specification.

After corrective action, the affected functionality should be retested and the result recorded. Hotels should avoid treating unresolved failures as accepted simply because equipment has been installed or a project deadline is approaching. Any exceptions should be formally reviewed and documented by the appropriate parties.
