Enterprise Architecture Maturity Assessment Case Study


This case study uses Gartner's Enterprise Architecture Program Maturity Self Assessment Framework and tools to conduct a detailed assessment of the enterprise architecture program at the State of Oregon


This Enterprise Architecture Maturity Assessment Case Study provides an insightful analysis of the journey of a large organization as it navigates the complex terrain of enhancing its enterprise architecture (EA) capabilities. Facing the challenge of modernizing its IT landscape, this organization undertook a comprehensive assessment to determine its current maturity level and chart a path for advancement.

Embarking on this endeavor, the organization confronted several obstacles. The initial assessment revealed that the components of its EA program were in their nascent stages, scoring 1.1 out of a possible 5.0. This score highlighted the program's infancy and illuminated both the potential and the hurdles for its growth and evolution. Key issues included limited stakeholder involvement and support, underdeveloped architecture definition processes, and insufficient alignment of EA with the organization’s business context.

To address these challenges, the organization focused on developing a robust framework for Iteration-1 of its EA program. This phase aimed to lay a strong foundation for future growth, targeting a maturity score 1.8. Despite staffing constraints and the unfunded and volunteer-based program, there was a commitment to building the necessary architecture scope, authority, and stakeholder support. The organization recognized the need for clear communication tailored to different stakeholder groups to garner their involvement and backing.

The assessment utilized the Gartner Enterprise Architecture Program Maturity Self-Assessment tool, covering crucial areas like architecture scope, stakeholder support, architecture development, business context, and future state realization. Despite the low consensus scores across these dimensions, there was a recognition that incremental progress was key to maturing the EA program.

In conclusion, this case study is a testament to the iterative and challenging nature of maturing an EA program. It underscores the importance of strategic planning, stakeholder engagement, and resource allocation in advancing EA maturity. The organization’s approach offers valuable lessons for similar entities embarking on this journey, emphasizing that while achieving the highest level of EA maturity may not be immediately feasible, setting realistic goals and making incremental progress is vital for long-term success and alignment with business objectives.
