VDI 2221 Blatt 2:2018-03

The standard describes the derivation from the logic of the model of product design described in VDI 2221 Part 1 into a specific product design process. The general model presented in VDI 2221 Part 1 is based on a systematic sequence of product design in which the development activity is divided into logical phases which differ in their objectives, activities, degree of maturity and extent. In this way, this model abstracts a real design process. Iterations or the simultaneous execution of different activities are not shown. To implement a real design process, the consideration of specific context factors is necessary. Context factors are the factors that influence the product development and must therefore be taken into account when designing the development process. In the specific context of a company, the objectives, activities and results of product design processes can be different, but they can be derived from the general 'model of product design' through appropriate concretion.
