Maturity models help organizations to measure the quality of their processes. These models are able to indicate how excellent business processes (BP) can perform and how organizations can reach the expected and higher performance. Maturity models aim at assessing and improving the capabilities, i.e., skills or competences, of business processes. However, finding the most appropriate maturity model is not an easy task especially for practitioners in manufacturing industry. Hence, the purpose of this paper is to critically propose a maturity model for the Collaborative Business Process (CBP) in a Service Oriented Architecture (SOA). We observed in the literature a lack of the evolution maturity over the time and its impact on the business process performance.
