Consumers do not always have the complete information about products. Therefore, a subjective assessment may be their only basis to determine quality differences among different suppliers. This subjective assessment of quality is based on image, advertising or brand name.
A company need not pursue all of these eight dimensions simultaneously. In fact, it is seldom possible unless the company intends to charge unreasonably high prices. Technological limitations may impose further constraints. In some cases, a product can be improved in one dimension of quality only while it becomes worse in another. Trade-offs among all these dimensions may therefore have to be considered.
