UK's Shared Services Strategy is entering the danger zone

The UK's Shared Services Strategy for Government is facing mounting challenges as it approaches its fifth anniversary, with legal disputes, departmental resistance, and escalating costs threatening to derail the ambitious £1.7 billion initiative.

On the eve of its fifth birthday, the strategy received two unwelcome presents. First, Sopra Steria launched a legal challenge against the Department for Work and Pensions' (DWP) decision to award a £370 million contract to Capita for running Oracle-based HR and finance services across four departments. The company, which already operates part of the service through its SSCL subsidiary, alleges the DWP failed to recognize Capita's bid as "abnormally low" and raises concerns about staffing levels.

This legal challenge is particularly significant because losing incumbents typically avoid contesting government procurement decisions to maintain future business relationships. However, Sopra Steria's willingness to pursue litigation suggests serious concerns about the tender process and the viability of Capita's low-cost bid.

Second, the National Audit Office delivered a sobering assessment of the program's progress. The watchdog's report revealed that departmental buy-in remains unclear, with His Majesty's Treasury—the department that has committed £1.15 billion in funding—yet to make a firm commitment to joining the Matrix shared service cluster. This creates a fundamental contradiction: the department providing most of the funding isn't fully committed to the strategy it's financing.

The Five-Cluster Approach

The strategy aims to consolidate 17 departments and 300 arm's-length bodies into five cloud-based shared services centers by 2028. Each cluster will operate on common processes and new ERP and HR systems:

Unity Cluster: Led by HMRC, this cluster includes 66,000 employees transitioning from SAP ECC to S/4HANA cloud. It also encompasses the Department for Transport and the Ministry of Housing, Communities and Local Government. The complexity of aligning different departments' processes and requirements cannot be overstated.

Defence Cluster: While seemingly simpler with only the Ministry of Defence, this cluster must integrate military and civilian personnel systems that have historically operated separately.

Overseas Cluster: Already live on Oracle Fusion under a £90 million Capgemini contract, this cluster serves the Foreign, Commonwealth & Development Office.

Matrix Cluster: Led by the Department for Science, Innovation & Technology, this cluster includes multiple departments and has already awarded Workday £144.3 million for SaaS finance and HR software, plus a Cognizant systems integration deal.

Synergy Cluster: Led by the DWP, this cluster includes the Ministry of Justice, Home Office, and Department for Environment, Food and Rural Affairs. Oracle and IBM won a £711 million ERP technology and systems integration contract, with Capita now awarded the £370 million operational contract.

Escalating Costs and Timeline Pressures

The financial commitment to the strategy already stands at approximately £1.7 billion, with some contracts extending for ten years. This includes:

• HMRC's £246 million SAP SaaS agreement
• Deloitte's £120 million systems integration contract for HMRC
• Workday and Cognizant's £144.3 million Matrix cluster contracts
• Oracle and IBM's £711 million Synergy cluster technology contract
• Capita's £370 million operational contract

These figures don't include additional procurement activities still in progress, suggesting the final cost could exceed initial estimates significantly.

Departmental Resistance and Implementation Challenges

Several departments have shown reluctance to fully commit to the strategy. The Department for Education has yet to fully commit to joining Matrix, while the Department of Health and Social Care is undergoing merger with NHS England, which is simultaneously migrating to Oracle.

HM Treasury's hesitation is particularly problematic given its role as the primary funder. The Cabinet Office maintains that departmental participation isn't optional, stating that departments cannot decide to move or leave a cluster without assessing value for money across government and the impact on the business case.

Technical and Organizational Complexity

The strategy's ambition creates enormous technical and organizational challenges. Moving from legacy systems to cloud-based ERP and HR platforms requires not just technology migration but fundamental changes to business processes. Organizations must abandon customized processes and adopt standardized workflows, which often meets resistance from users accustomed to existing systems.

For instance, HMRC's transition from SAP ECC to S/4HANA involves eliminating small but complex customizations and adopting entirely new standard processes. This transformation affects 66,000 employees and requires extensive change management, training, and process redesign.

The 2028 Deadline Looms

The 2028 deadline for operational shared services centers is approaching rapidly. With legal challenges underway, departmental resistance mounting, and implementation complexities becoming apparent, the strategy faces significant risks of delay or failure.

The National Audit Office's report highlights that buy-in from departments is not clear, creating uncertainty for the overall strategy. This uncertainty is compounded by the fact that some departments are simultaneously undertaking their own technology migrations, creating potential conflicts and resource constraints.

Broader Implications for Public Sector IT

The UK's Shared Services Strategy reflects a broader trend in public sector IT toward consolidation and standardization. However, the strategy's challenges illustrate the difficulties of implementing such ambitious programs at scale.

Questions are emerging about whether organizations need to be tied to major vendors' upgrade paths or whether more flexible, atomized approaches might be preferable. The concept of a "SaaS-pocalypse"—where organizations become locked into expensive, inflexible cloud solutions—is gaining traction among users and analysts.

What Success Would Look Like

If successful, the strategy would deliver 10-15 percent operating cost savings, or approximately £1.8 billion over 15 years. This would be achieved through reduced system duplication, standardized processes, and economies of scale in service delivery.

However, the path to these savings is fraught with challenges. The pain of agreeing on new ways of working, deploying new technology, and achieving user adoption can be so great that early promises are never kept. As timelines stretch and technology choices age, the original business case may become increasingly difficult to justify.

Looking Ahead

As the 2028 deadline approaches, the UK government faces a critical juncture. The strategy's success depends on resolving legal challenges, securing departmental commitment, managing implementation risks, and delivering promised benefits.

In a couple of years, we will discover whether the Shared Services Strategy represents a successful transformation of public sector IT or another cautionary tale about the challenges of large-scale government technology programs. The stakes are high, with £1.7 billion already committed and the efficiency of nearly half a million public workers depending on the outcome.

For now, the strategy appears to be entering the danger zone, where ambitious plans meet the harsh realities of implementation, organizational resistance, and technical complexity. Whether it can navigate these challenges successfully remains to be seen.
