Modernizing ITSM for a centuries-old global insurer

  • One of the world’s oldest general insurers, established over 300 years ago, operates across the UK, Ireland, Europe, and the Middle East.
  • A six-year-old lift-and-shift ServiceNow migration had created compounding technical debt, duplicate CMDB records, and fragmented processes.
  • Brillio conducted a full legacy assessment, applied ITIL 4 and SIAM frameworks, and rebuilt the ServiceNow platform on a unified, governed foundation.
  • The transformation delivered faster service delivery, reduced MTTR, lower total cost of ownership, and stronger compliance across the enterprise.

From fragmented legacy systems to a future-ready ITSM platform

Challenge

Six years before engaging Brillio, the client had migrated its IT service management platform from Remedy to ServiceNow. The method was a straightforward lift and shift, meaning the underlying processes, data structures, and configurations came across largely unchanged. Over time, this approach left the organization carrying significant technical debt with no clear path to resolution.

The problems were concrete and compounding. The configuration management database contained outdated and duplicate records, the result of an unreliable data feed that had never been properly addressed. Without ITSM and ITOM Pro modules in place, the platform lacked the operational capabilities the team needed to work effectively. Central Support was running on separate processes and tools, introducing unnecessary complexity and friction across service delivery.

The consequences of these gaps were felt throughout the organization. There was no reliable way to gain meaningful performance insights, which meant strategic decisions about service quality were being made without solid data. Visibility into the broader IT estate was limited. End users and operations teams were absorbing the inefficiency in their daily work, and the cost of maintaining a fragmented, underperforming platform continued to climb.

For an insurer with over 300 years of history serving individuals and businesses across the UK, Ireland, Europe, and the Middle East, the inability to manage IT services efficiently was not just an operational problem. It was a risk to the business. The client recognized this and sought a partner with deep expertise in enterprise service management transformation.

Solution

We began the engagement with a structured assessment of the client’s existing ITSM landscape, drawing on policies, processes, key performance indicators, and direct stakeholder feedback to build a complete picture of where the platform stood and what it needed to become. Rather than applying a generic remediation plan, our team identified specific opportunities to use ServiceNow’s out-of-the-box capabilities to improve functionality while reducing complexity.

The transformation strategy was grounded in two established industry frameworks: ITIL 4 and SIAM. These provided the architectural and governance logic for defining a scalable target state. A hybrid waterfall delivery methodology was used to keep the program structured while allowing the flexibility needed to respond to stakeholder input as the work progressed.

A governance framework was developed and refined iteratively in close collaboration with key stakeholders and third-party suppliers, ensuring that every process change had organizational buy-in rather than being imposed from the outside.

On the platform side, we consolidated the ServiceNow environment and created a unified CMDB to address the data accuracy problems at their source. ServiceNow discovery tools were deployed to give the client clear, reliable visibility into its IT estate for the first time. An ITSM training program was rolled out to accelerate adoption and build lasting user competency across the organization. Alongside this, we established a continuous measurement framework, giving the client the means to track the value of its ITSM investments and drive ongoing process improvements well beyond the end of the engagement.

Measurable gains across efficiency, risk, and user experience

Outcomes

  • Automation and integration eliminated process redundancy, reduced operational waste, and improved overall cost-effectiveness across the ITSM function.
  • Faster response times and standardized processes improved service delivery agility and reduced mean time to resolution for end users.
  • A unified CMDB and strengthened governance framework improved compliance, reduced operational risk, and created a single reliable system of record.
  • The ITSM training program and continuous measurement framework embedded lasting competency and a culture of ongoing service improvement across the organization.

ServiceNow modernization cut costs and increased agility

We modernized the insurer’s ServiceNow-based ITSM function with best-practice processes, unified CMDB governance, discovery-led visibility, and user training. The result was a more agile, resilient service environment that improved service delivery, reduced operational risk, enhanced user satisfaction, and lowered total cost of ownership.
