Major glitch in Matrix as UK government projects watchdog rates shared services cluster red
The UK government has confirmed that Matrix, a project to move nine departments onto shared ERP and HR systems, has been rated "red" by the National Infrastructure and Service Transformation Authority (NISTA), meaning its problems with schedule, budget, quality or benefits delivery do not currently appear manageable. Matrix is a key part of a wider £4.3 billion shared services strategy intended to migrate 17 departments and 300 arms'-length bodies onto common tech platforms, so serious setbacks here cast doubt on the broader programme's viability.
Matrix, led by the Department for Science, Innovation and Technology, had awarded Workday and Cognizant contracts worth a combined £144.3 million in 2024, with go-live originally due in May 2026. Replanning is now under way after emerging analysis pointed to a 3-6 month delay, pushing Phase 1 go-live to late 2026, with the main risk being departments' lack of expert capacity for required testing. His Majesty's Treasury and the Department for Education have both delayed decisions on joining, despite being told participation was not optional, while NISTA also rated the related Unity programme, covering HMRC's move to a cloud-based SAP system, as red, albeit with improving progress.
In short
- NISTA rates the government's Matrix ERP project "red" over unresolved delivery issues
- Go-live pushed back 3-6 months to late 2026 amid testing capacity concerns
- Treasury and Department for Education still hesitant to commit to joining Matrix
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Large-scale government technology transformations are inherently complex, and encountering delays is a normal feature of ambitious programmes rather than evidence of fatal flaws. Consolidating departments onto shared ERP and HR platforms can deliver substantial long-term operational savings and reduce fragmentation that plagues public-sector IT, and with replanning underway and timelines adjusted to late 2026, the project retains a viable path forward. Abandoning the programme now would squander investments already made and forgo the efficiency gains that shared infrastructure can provide.
The case against
The red rating, combined with testing capacity shortages and reluctant department participation, suggests fundamental problems with this £4.3 billion mega-project rather than routine implementation challenges. Government has a poor track record delivering large-scale IT transformations, and attempting to force 17 departments and 300 bodies onto a single platform is a high-risk approach that warrants scepticism. The fact that Treasury and Education are delaying decisions despite being told participation is mandatory indicates that even government itself lacks confidence in the enterprise.
Explained simply
Matrix is a major UK government project aimed at consolidating nine departments onto shared computer systems for managing finance, human resources and other core business functions. It is part of a much larger plan to move 17 departments and hundreds of related organisations onto common technology platforms, with a total budget of £4.3 billion, so difficulties with Matrix could jeopardise the entire strategy.
The project is led by the Department for Science, Innovation and Technology and involves contracts with technology firms Workday and Cognizant. The original plan was for the first phase to become operational in May 2026, but the project team has identified significant delays that will push this back by between three and six months, largely because the participating departments lack sufficient expertise to complete the necessary testing.
The delays have raised concerns about the viability of the broader shared services programme. The Treasury and Department for Education, both originally scheduled to join Matrix, have delayed their decisions despite being told participation was mandatory, and a related project covering the tax authority's migration to a cloud-based system is also facing challenges.
