A design specification provides explicit information about the requirements for a product and how the product is to be put together. It is the most traditional kind of specification, having been used historically in public contracting for buildings, highways, and other public works, and represents the kind of thinking in which architects and engineers have been trained. Its use is called for where a structure or product has to be specially made to meet a unique need. For example, a design specification must include all necessary drawings, dimensions, terms, and definitions of non-standard terms, and the materials used must be described fully to include thickness, size, color, etc.
