In order to ascertain and measure supply chains, a wide range of supply chain maturity assessment models have been developed. Maturity models represent stages through which processes and organisations progress as they are defined, implemented and improved. The purpose of maturity models is to assist organisations to compare the maturity of their processes against best practices and further guide in the development of an improvement roadmap. Despite the proliferation maturity models, the maturity models have been troubled by criticism such as; maturity models lack strong theoretical foundation and empirical validity. It is however the primary objective of this study to investigate this claim by performing a comparative analysis of supply chain maturity models. The results of this paper are meant to serve as a manual for a detailed understanding of the documented supply chain maturity models.
