It is difficult for me to provide you with what you are searching for, “clarification”.
Why do I say that? Because I don’t have an ISO 9000 definition of what is TQM. Sure the internet is full of definitions, but I would like to work with an authoritative one.
Some authors say that QMS has a wider scope than TQM and others say the exact opposite. In my opinion, and this is just my opinion, TQM and a QMS seek to achieve the same kind of result. However, TQM focuses much more on improvement projects aimed at continually improving performance and customer satisfaction.
