Maturity Matters: How to Systematically Evolve Your Enterprise Architecture Capability

written by

Marina Poppa, Lean42 GmbH


Enterprise Architecture (EA) is a critical enabler for aligning strategic IT decisions with overall business objectives. It provides transparency across complex structures and dependencies, empowering organizations to make informed decisions and implement change in a targeted and effective manner.

But how well is your EA truly embedded in practice? Where are your strengths – and where is there room for improvement?

A structured maturity model offers the clarity and foundation needed to answer these questions. It enables you to assess your current state across clearly defined dimensions and derive concrete, targeted improvement measures.

An effective EA maturity assessment typically evaluates your capabilities across these five dimensions:

  1. Business Value – What contribution does your EA function make toward achieving business goals?
  2. Leadership – How well is EA integrated into management, governance, and decision-making processes?
  3. Methods & Artifacts – Which methods, models, and tools are in use, and how mature are they?
  4. Team & Skills – How is the EA team structured in terms of expertise, capacity, and internal recognition?
  5. Use & Participation – To what extent is EA adopted and embedded across the organization?

Most models define five maturity levels – from initial, informal practices to a fully institutionalized, strategically aligned EA function. Regardless of whether your organization is just starting or already has an established practice, an assessment provides a clear baseline and action plan for growth.

In our proven framework, our international EA experts outline a practical seven-step approach to maturing EA skills:

  1. Clarify Purpose – Clearly define the value and mission of your EA function.
  2. Assess Current State – Understand where your organization currently stands.
  3. Define Target State – Articulate a realistic yet ambitious vision for EA maturity.
  4. Build Roadmap – Develop a practical, phased roadmap for achieving that vision.
  5. Align & Engage – Ensure alignment and buy-in from key business and IT stakeholders.
  6. Establish Governance – Put in place the structures, roles, and decision rights to support EA.
  7. Review & Evolve – Continuously measure progress and refine your EA strategy over time.

This step-by-step model enables organizations to transform EA from a conceptual framework into a business-critical capability – strategic, operational, and cultural.

A structured EA maturity assessment delivers tangible value:

✔ Clear starting points for improvement
✔ Alignment with industry best practices
✔ Prioritization of high-impact measures
