PurposeThe aim of this article is to develop an efficient method for the assessment of business process management (BPM) maturity, which identifies the present maturity level in the organization, as well as integrates itself with the methodology of implementing BPM and systemically eliminates the identified limitations of existing BPM maturity models (BPM MMs).Design/methodology/approachThe methodological underpinning of this research involves a comprehensive review and critique of existing BPM MMs, dissecting their theoretical foundations and methodological constructs. Grounded in established research methodologies, the study integrates perspectives from Industry 4.0 and Industry 5.0.FindingsThe presented BPM maturity assessment (BPM MA) is targeted at showing the actions that lead to raising BPM maturity by drawing upon the potential of the organization in a way which is harmonious with methodologies of implementing and using BPM. It focuses on practical usability and, thanks to this, eliminates one of the most often discussed flaws of BPM MMs.Research limitations/implicationsThe limitation of this study is, at this stage, the lack of empirical verification and the lack of postulated BPM MA tools, integrated with the BPM software available on the market. Though the proposed BPM MA offers a systematic approach, targeted at practical use, it will, however, in the further perspective, require tailoring to the specific nature of different sectors of the economy in order to reach its full potential by, e.g. adapting the evaluation surveys and adding dedicated recommendations.Practical implicationsPractitioners may reap the benefits of the presented BPM MA thanks to its harmonization with methodologies of implementing BPM and the possibility of its use as an element of the standard BPM lifecycle. Accounting for the requirements of Industry 4.0/5.0 in both assessment criteria and recommendations provides managers support in the rapidly changing business environment.Originality/valueThe originality of this study rests in the synthesis of theoretical and methodological rigor with a singular focus on the practical usability of the proposed BPM MA. Apart from conceptual progress, the contribution of this study rests in removing the theoretical-practical gap and accounting for the requirements of Industry 4.0 and the upcoming Industry 5.0.
