R&D and Quality control are two different sectors which are dependent on each other. Even though research of a particular product would inititate the development of a product, the application of the particular product into the real world would never be processed without QC. As in the QC, the pros and cons of product and the utility and necessity of the product is taken as a main concern. Only if the product has a product quality evaluation it is validated to apply into the real world population. Quality deals with the well being of the population which is the ultimate goal of research. Only if QC has a proper results then R&D had evaluated.
