Which model helps assess and improve an organization's architecture capability?

The Architecture Capability Maturity Model (ACMM) is designed specifically to evaluate and enhance an organization’s architecture capability. The model provides a structured framework for organizations to assess their maturity levels in architecture practices and to identify areas for improvement. By following the ACMM, organizations can better understand their current capabilities, establish benchmarks, and create a roadmap for advancing their architecture practices over time.

The model typically outlines different maturity levels, each describing specific characteristics, competencies, and performance indicators associated with architecture capabilities. This helps organizations to not only assess where they currently stand but also to formulate strategies for progressing to higher maturity levels, ultimately resulting in more effective and integrated architecture practices.

In contrast, other options might focus on different aspects of architecture governance or principles but do not provide the comprehensive assessment and improvement framework that the ACMM offers. The Architecture Governance Framework, for example, is more about establishing processes and structures for governance rather than assessing maturity levels, while Architecture Principles are guidelines that inform decision-making without a focus on maturity assessment. An Architecture Matrix may aid in organizing various elements of architecture but lacks a mature capability-focused approach.
