In this contribution an original Purchasing and Supply Management Maturity Frame-work (PSM2F) is going to be presented based on the findings of a comprehensive literature and empirical research and a comparative analysis of maturity/stage models published between 1983 and 2014 as well as (management) frameworks published between 1998 and 2014 in Purchasing and Supply Management (PSM). In total 20 maturity models published from authors with an academic or scientific background, 18 maturity models offered from consulting firms and 19 management frameworks of purchasing management were examined. Beside the presentation of eight core modules that contribute to a mature and professional PSM (e.g. strategy & plans, controlling & performance management, organization & internal interfaces, supplier management & external inter-faces), content-related as well as descriptive findings are going to be discussed. Based on that, the development as well as the overall concept of the Purchasing and Supply Management Maturity Framework will be presented. To cover also the future aspects of professional PSM, 16 studies about trends and challenges in PSM were analysed. Contrary to the large part of the published maturity models in PSM, this framework is de-signed as a management model for (1) the assessment of the PSM maturity in a company and (2) the creation of an improvement roadmap that should lead to higher maturity. In addition to the hard facts (What a company has to do to reach higher maturity in PSM?) also soft facts (How to proceed to reach higher maturity in PSM?) derived from change management theory will be addressed.
