Cycles play a decisive role in innovation and development processes. Iterations and engineering changes as one perspective on cycles have a major influence on both value generation as well as resource consumption within the process. While several initiatives are addressing this field of research, methods for coping with iterations and engineering changes more effectively and efficiently are still needed. This research contributes an explanatory model of cycles, iterations and changes that integrates both a system perspective and a context perspective on the development process. The modeling concept is evaluated by modeling examples from the development process of a SAE Formula student race car. The results show that the model allows for (1) a more precise analysis of iterations and changes, (2) for the derivation of hypotheses for handling iterations and changes and (3) for a subsequent operationalization.
