Abstract. Throughout the recent years research about maturity models as well as their application possibilities has vastly increased in all sorts of organizations and institutions. The range of the topics they address has expanded as much as the way they can be structured and applied. One area, where the use of maturity models can have a great impact, is product lifecycle management (PLM). PLM is becoming more and more essential for companies as a way of staying competitive on any market due to enhanced understanding of complex processes and increased efficiency in the use of information throughout all stages of the lifecycle. In this regard, maturity models can be beneficial as methods to assess the organizations' product lifecycle processes, illustrate improvement opportunities and even customize a roadmap to exploit them. However, considering the complex application options of maturity models, it can be difficult to choose an appropriate model for a certain purpose. This paper will provide a comparison framework for maturity models in the PLM area. The collected attributes as well as their categorized comparison shall provide guidance in choosing the correct maturity model depending on the user requirements.
