To me "conformance to the requirements" means "good enough", which is one possible level of quality. Quality is about a whole range of not only meeting requirements (or not) but also about above and beyond. I think people will generally perceive a item to be of higher quality when it doesn't fail when they abuse it out of spec a bit. You can often charge more for a item that has perceived higher quality compared to one that doesn't, even if both perform correctly just to the specs. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
