Understanding Business Process Maturity Models: CMM, AIMM, and How to Choose the Right Model

When building a company, team, or any system you need ways to measure how well you are doing, set basic standards, and compare them to best‑practice benchmarks; traditional metrics like KPIs and OKRs often struggle with qualitative data, which is where maturity models become useful.

What Is a Maturity Model?

A maturity model shows an organization’s ability to achieve continuous improvement; it judges performance based on how well the organization self‑optimizes.

Continuous improvement is the core idea behind effective systems, from business process management to ISO standards, and maturity models help quantify that progress.

How We Use Maturity Models and Their Benefits

Process Street created a Blog Asset Maturity Model (BAMM) to evaluate blog content across five levels, covering editorial process, peer review, and workflow, turning qualitative aspects into measurable scores.

What Are the Limitations of Current Business Process Maturity Models?

Research by Van Looy, Poels, and Snoeck identified nine BPMM variants (e.g., BPM‑CF, BPMM‑FIS, BPO‑MM) but found that only a few have been empirically validated; many models are overly complex or lack practical guidance.

Among the studied models, BPO‑MM appears most applicable in real‑world settings, being referenced in four out of seven empirical studies.

What Is the Capability Maturity Model (CMM)?

CMM, originally funded by the U.S. Department of Defense, defines five levels—Initial, Repeatable, Defined, Managed, Optimizing—to assess and improve software development processes, though it can be applied more broadly.

What Is the Agile ISO Maturity Model (AIMM)?

AIMM combines agile business‑process management with ISO standards, offering five levels: Documented Process, Followed Process, Managed Process, Optimized Process, and Integrated Process, each adding more rigor and data‑driven improvement.

Level 1 ensures processes are documented; Level 2 requires consistent execution; Level 3 adds management and analytics; Level 4 focuses on optimization using rich data; Level 5 integrates new processes to extend organizational capabilities, even supporting sustainability initiatives.

Conclusion

Maturity models provide a structured way for managers of any size to assess and improve their processes; while many existing BPMMs are overly theoretical, a practical, actionable model—such as the Agile ISO Maturity Model—can bridge the gap between theory and everyday business needs.
