AbstractBusiness Process Maturity Models (BPMM) offer organizations an approach to improving business processes. However, criticism of the usefulness of BPMMs in improving operational efficiency exists in the literature. Hence, a systematic literature review was conducted, thematically analyzing forty-seven studies about BPMMs. The paper provides an in-depth understanding of the limitations and the extent to which these problem areas have been addressed, aiming to provide a foundation for future research in improving the usefulness of BPMMs. [ABSTRACT FROM AUTHOR]
