Not being totally familiar with QS9000 and it's requirements, I would like to ask a question. Is it common practice in QS9000 to rank suppliers on a Red, Yellow, and Green color status? Is this a new concept and where did it originate?
Red/Yellow/Green rating is a good way to present an evaluation of some system (very visual). We use R/Y/G rating for many different rating systems. Just make sure and define what a Red, Yellow, and Green rating mean. We had an audit finding because we were using R/Y/G to rate the elements in the Management Review, but had not specifically defined each category.
