Product development is a business process where a great number of different functionalities and internal and external interests are intertwined. Involvement of human beings, traditional development structures, specific external conditions and internal resources let almost every development process appear as one of a kind. The modeling and documentation of processes is a prerequisite for reengineering and continuous improvement of development systems. International case studies conducted by the Institute of Astronautics revealed the usefulness of a method which fits to all product development systems in general and provides a principal classification of the different processes involved. In addition, this method should be flexible enough to derive the particular profile of a product development system analyzed. This paper describes the Product Development Cycle Model (PDCM), a new and robust approach which meets these requirements. Starting and ending with customers' requirements, the PDC‐Model especially highlights the importance and impact of strongly interconnected loops and control cycles within a product development system. First we explain typical characteristics that can be used to describe development processes. Then we explain the Product Development Cycle and its distinct sub‐cycles. Finally, we show a current example from a case study.
