Strategic CMS selection at VGZ.

From legacy monolith to a widely supported headless choice

How a structured selection process laid the foundation for the new digital architecture of VGZ.

The Challenge.

As one of the largest healthcare insurers in the Netherlands, VGZ's digital services are critical for both members and partners. Over the years, the existing Content Management System (CMS) had grown organically, but it had eventually become a barrier to innovation. The primary bottlenecks were:

  • Operational Risks: As the platform grew sharply in size and complexity, knowledge of the system ended up concentrated in a handful of people. The focus shifted increasingly toward firefighting rather than building value. At the same time, the content team grew rapidly: without central governance on tone of voice and publication processes, VGZ lost its grip on what went live. Alongside a new CMS, VGZ is therefore also redesigning its content organisation and processes.
  • Stagnating Innovation: The CMS has become so technically extensive that adding new functionality keeps getting harder. On top of that, the underlying software is outdated and isn't evolving alongside modern capabilities such as AI applications.
  • Bundled Functionality: The current monolith contains a lot of functionality that doesn't normally belong in a CMS, such as email, forms and personalisation. VGZ wants to move these components into systems purpose-built for them. But as long as they're inside the CMS, they need to come out first.
  • High Costs: Much of the CMS's current functionality goes unused, while high licensing and maintenance costs still have to be paid.

VGZ engaged Breakfast to lead the selection process and bridge the gap between business requirements and technological possibilities.

Team at work during the CMS selection process

Our approach.

Our methodology was designed to separate the 'noise' of features from actual business value. The process consisted of three phases:

  1. 1

    From Strategy to Use Cases: We started with an intensive kick-off and stakeholder interviews across all disciplines. Instead of a static list of hundreds of requirements, we translated the roadmap and pain points into five core use cases. These cases served as the ultimate litmus test for every vendor, supported by approximately 80 prioritized (MoSCoW) functional and non-functional requirements.

  2. 2

    Market Validation (RfP): Based on the architectural landscape, we compiled a long-list of five headless CMS vendors. During the RFP phase, we looked beyond technology; we evaluated roadmaps, pricing models, support structures, and the 'fit' with the organisation's security requirements and architecture. This resulted in a shortlist of three parties.

  3. 3

    The Sandbox: Proof in Practice: No paper promises, but practical testing. For two weeks, the shortlisted vendors provided an environment in which VGZ's team tested the use cases live. Topics such as content creation, multi-site management, integration, AI applications, and content modeling were evaluated by the users themselves.

The result.

Within three months, we achieved a result that is widely supported throughout the entire organization:

  • Unified Choice: A unanimous selection of a CMS that aligns seamlessly with the organisation's new headless architecture.
  • Value-Driven: By emphasizing use cases, the choice was based on daily efficiency rather than unnecessary 'bells & whistles'.
  • Strategic Insight: The selection process acted as a mirror; it provided the organisation with immediate insight into the necessary optimization of internal processes and governance.
  • Roadmap for Success: The process did not end with a signature. We delivered the initial framework for a phased, low-risk rollout strategy.
