Variety A diversity or difference in design elements in varying degrees. An opposition of design elements in varying degrees. A harmonious relationship of all design elements woven together. Advice and opinion should always be sought either from within the company or without. Sales, marketing, production and others will always criticize a design once it exists.
Every person is a design critic, accomplished or otherwise.
So often the final appearance of a product 'just happens' and then strenuous efforts are made to make it look better, which usually prejudices the design in all aspects. The visual performance is always first. No liability for the implications or consequences of its use may be attributed to the author.
