Multi-Year Architecture Maturity Programme For A Healthcare Provider

Healthcare Services
Context

The Architecture Practice within a UK-based healthcare provider had established core services, including enterprise architecture, solution architecture, governance, standards, and knowledge management.

The client wanted to understand how effectively these services supported business and technology change.

Improvement meant more than refining architecture processes; it required a consistent, trusted, and measurable service that could shape technology investment, support delivery teams, improve decision-making, and demonstrate value to executive stakeholders.

To achieve this, the client needed a clear view of the practice’s maturity, priority improvement areas, and ways to measure progress over time.

Objective

To assess the maturity of the Architecture Practice’s capabilities, benchmark them against recognised industry best practice, and identify the improvements required to strengthen the value and effectiveness of architecture services.

The assessment also needed to create a clear improvement roadmap that could be used to engage stakeholders, secure buy-in, prioritise activity and support investment decisions. This would enable the client to move from identifying improvements to delivering them, measuring progress and extracting value from the Architecture Practice over a multi-year period.

Action

Mosaic Island conducted an architecture maturity assessment using our proprietary Architecture Framework.

Through stakeholder interviews, artefact reviews, and assessments of governance and delivery practices, we evaluated each capability area against TOGAF maturity levels. This provided a clear baseline of current maturity across the Architecture Practice and identified where improvements would have the greatest impact. In addition, it informed a series of short-, medium- and long-term initiatives to strengthen architecture capabilities and services. These included improvements to architecture governance, policies, standards, guardrails, ways of working, artefact management and knowledge management.

We worked with the client to define target maturity levels for each capability area, ensuring these were aligned to the organisation’s objectives and the role architecture needed to play in supporting business and technology change.

Mosaic Island also supported the client in using the assessment outputs to communicate progress and priorities with key stakeholders. This helped direct improvement activity, build confidence in the Architecture Practice, and support the case for ongoing investment and funding.

Over a four-year period, Mosaic Island repeated the assessment at key stages of the client’s maturity journey. This allowed the client to measure long-term progress, refine recommendations, evidence improvement and continue focusing activity on the areas that would deliver the greatest value.

 

Outcome

Strengthening Architecture Services

The Architecture Practice has made significant progress since the initial assessment.

By implementing key improvement initiatives, the client strengthened architecture governance, established clearer architecture policies, standards and guardrails, and introduced more consistent ways of working. It also improved the management of architecture artefacts and knowledge, enabling architects and stakeholders to access more reliable information about the current technology landscape and future architectural direction.

As a result, the Architecture Practice delivered more consistent and effective services. Architects and stakeholders gained greater visibility of both the current technology landscape and future architectural direction. In turn, this strengthened alignment between business strategy, technology investment and the delivery of change.

Creating A Measurable Improvement Journey

The repeated maturity assessments gave the client a structured way to track progress over time. Rather than treating architecture improvement as a one-off activity, the client was able to manage it as a multi-year maturity programme. This provided evidence of improvement, helped prioritise future activity and enabled the Architecture Practice to demonstrate the value it was delivering to stakeholders.

A Trusted Partner

The Architecture Practice now plays a greater role in shaping business and technology decisions. It is recognised as a trusted partner that helps align technology investment with the client’s priorities, supports delivery teams, and contributes to the successful delivery of change across their organisation.
