As part of this work, a comprehensive analysis of existing IPMs in literature is carried out. The analysis is based on Albers' and Schumpeter's understanding of innovation and the descriptions and representation of IPMs in literature. Frequently recurring components or noticeable differences in the literature are identified and used as criteria for further analysis. The criteria are categorized to show the results in table form to provide a clear and quick overview. Key Points highlight similarities and differences of the models, focusing on frequently recurring phases such as idea generation, technical realization (invention) and market launch. In addition, structural contents such as sequential processes, parallel activities and feedback loops are analyzed. It is identified that these are idealized processes to present basic procedures clearly. Therefore, feedback loops or iterations are neglected. An innovation impulse is often triggered by a customer need or problem, whereby these phases are included as upstream activities. Customer integration and decision points are not explicitly included in most models, but decisions to stop or continue ideas are regularly made. The focus of the models varies, with newer models incorporating agile methods alongside classic sequential processes. The aim is to support users in identifying similarities and differences between own process models and the models in the literature. The procedure for analyzing a case study is presented as example. This clear presentation of differences and similarities enables companies to adapt and further develop their innovation processes to meet specific requirements.
