The project director cleans the data to ensure its integrity and develops the tab specifications for review by the supervisor or QA Director. Data tables are run, reviewed and checked before the client ever sees them. A post-project client survey is an integral part of every job. The job itself is evaluated as well as the bid and billing phases. And there's no carpet to sweep things under.
Any negative feedback is addressed with the client and internally.
We learn as we live. We welcome questions and feedback from existing as well as prospective clients.
