The Challenge

Building foundations while executing at scale

The department faced a critical dual challenge. First, it lacked an operating model for the private cloud and on-premises hosting capabilities that would house migrated applications, no clear framework for how services would be managed, funded, or delivered. This gap threatened the entire program’s success. Second, the department needed to migrate more than 250 business services—some over 20 years old—rapidly and safely. Service owners were deeply concerned about risks to live operations, while the organization needed to move quickly to achieve substantial cost savings and ensure minimal disruption to critical government services that citizens depend on daily.

The Solution

Strategic foundation paired with accelerated execution

Credera deployed highly experienced senior teams across two critical workstreams. For the operating model, Credera worked closely with an extensive stakeholder community to develop a comprehensive target operating model design and implementation plan. The team created a detailed funding model for financial sustainability, developed clear service overviews, and communicated expectations to application owners about the new hosting environment. Credera also secured additional labor to resolve resourcing constraints.

For the migration, Credera engaged directly with IT leadership at the highest levels to secure organizational commitment. The team established a cross-functional working group covering service acceptance, operations, service management, and customer engagement to rapidly resolve issues. Credera created bespoke key performance measures to continuously monitor and optimize the migration process throughout the program.

The Results

Comprehensive transformation enabling sustainable cloud operations

The department now has both a robust operating model foundation and a proven, scalable service transition approach that supports its ambitious cloud transformation objectives.

As a result of this initiative, the department has experienced the following:

• Secured significant funding: Obtained over £1 million in funding for operating model implementation, ensuring adequate resources for success

• Reduction in transition time: Achieved a 6-week reduction (25%) in end-to-end service transition time per service, accelerating overall program delivery

• Stakeholder alignment: Created shared understanding among senior stakeholders, eliminating potential conflicts between the migration program and private hosting team
