Let me remind you (because it is worth it), at quality.com.au we claim to design, develop and implement quality management systems. We are even certified to ISO 9001 to do so. Nice huh!
Our controls are the contracts, checklists and quality plans we develop as part of the project plan. Next our design outputs are subjected to internal audits, external audits and even peer review as EVERY project has an assigned project director to ensure all facets of every project is delivered. And finally, that all important control of changes. We use contract variations if the scope is changed. We use design and project review meetings to record and mitigate change. We use myQuality reviews to ensure changes are managed in a controlled fashion and that relevant documentation is managed.
I don’t mind saying that we have a 100% certification success track record with our 300 plus quality management systems that we have deigned. That’s gotta be some form of validation!
