This paper presents instructions to support finding the best design step sequence for product development. Aiming at the detailed navigation questions of practical development, it can be seen as an enhancement to the more general VDI 2221. The proposed design procedure supports dealing with the uncertainty by giving a better orientation to the goals throughout the design process and so to generate as efficient as possible the relevant product knowledge. The backbone of the proposed instructions is a special product model called “influence net”. It enables to do objective decisions that may be checked when more product knowledge is available, which is most important for dealing with the uncertainty. Furthermore, the influence net gives precise answers to all decision and orientation questions that arise during product design. It allows to integrate more complex aspects as dynamic goals, decisions that take into account detailed market segments and the adoption of the dimensioning factors for each variant.
