DevOps uses a capability model, not a maturity model

Steve Fenton argues against using maturity models in DevOps, recommending instead a capability model that emphasizes continuous improvement and adaptability to changing business landscapes. Maturity models, which are activity-based and follow a linear, standardized approach, are deemed inappropriate for DevOps due to their rigidity and focus on achieving a fixed end state. In contrast, capability models are outcome-based, dynamic, and contextual, encouraging teams to connect their efforts with measurable results and adapt to their specific scenarios. The DevOps capability model, aligned with DORA metrics, helps organizations identify and implement the capabilities that will most effectively enhance their performance. By using this model, organizations can focus on constant incremental improvements rather than adhering to a pre-determined set of activities, fostering innovation and better alignment with business goals.
