Though it is desired to have a product that can be excellent in all nine dimensions, it is practically very difficult to design and manufacture a product that can be excellent in all dimensions. Since these dimensions are independent to each other, a product can be excellent in few dimensions and average or poor in other dimensions. Therefore, the product quality is usually evaluated by using a few of the dimensions of quality.
