Critical literature review on maturity models for business process excellence

Maturity models are a useful way for an organisation to assess their processes and the overall maturity levels of the organisation. However, finding the most appropriate maturity model is not an easy task especially for practitioners in industry. Hence, the purpose of this paper is to critically review, compare and contrast the existing maturity models in quality/operations management topics. This paper has reviewed the most common maturity models including but not limited to Bessant's continuous improvement capability model, Capability Maturity Model (CMM) and Capability Maturity Model Integration (CMMI) which is the most common model in the literature. The authors have observed a lack of maturity models for process management. Therefore, the future plan for this research is to develop a maturity model for a specific area in process management, which is Lean Six Sigma (LSS), as this is the main area of interest for the authors.
