The process of product development is a problem-solving process characterized by the continuous handling of uncertainties by development teams. For this reason, companies in the field of mechatronic system development implement agile approaches in their development processes in order to deal adequately with these uncertainties, which, however, reach their limitations in individual areas due to different characteristics of physical products. In addition, the development processes contain problems that are of a complicated or simple nature and can therefore be sufficiently planned and solved by plan-driven procedures. For this reason, in the present contribution principles from the literature are derived that support developers in their activities in mechatronic system development. In addition, a model is presented that allows developers to assess the planning stability of individual process elements at different process levels and thereby implement a situation- and demand-oriented degree of agile process elements into the development process.
