It is well recognized that functional design plays a central role in ensuring design quality and product innovation; products with problems in their main functions do not sell well, no matter how sophisticated their details. Numerous examples exist of products marketed and sold as sophisticated but routinely fail to perform the intended functions or do so in a very unsatisfactory manner. The paper reviews functionality in design, with a special emphasis on the different definitions of function as well as the models and tools used to represent function in a product.

Keywords: design process, functionality, reliability, concurrent engineering
