Architecture Maturity Assessment
Know where your architecture capability really stands — and what it takes to reach the next level of maturity.
Understanding This Service
What We Evaluate
We evaluate the maturity of your enterprise architecture function across five dimensions: governance, methodology, stakeholder engagement, tooling, and business value delivery — benchmarked against TOGAF and CMMI standards.
Benchmarked Against Industry Standards
Our maturity model draws on TOGAF Architecture Capability Framework and CMMI for Services, providing a recognised benchmark that enables meaningful comparison and goal-setting.
A Practical Maturity Roadmap
The assessment concludes with a targeted maturity improvement roadmap — specific, sequenced steps to close gaps and build a more effective, value-generating architecture practice.
