Key findings
Tata Consultancy Services
DWP spending records repeatedly identify payments to Tata Consultancy Services for “CMS 2012 Core” and Child Maintenance technology work.
TCS supports CMS predictive analytics
DWP’s algorithm record describes supplier involvement in the design, build, assurance and support of the predictive compliance service.
User activity is audited
DWP’s client-fund accounts confirm an Audit Trail process designed to give a consolidated view of audited staff activity on DWP systems.
Wrong Liability Order figure
DWP’s serious-case learning records describe a case where the wrong arrears amount was calculated before a Liability Order application. DWP reported a resulting system change.
Contract KPI refers to technical payment queries
DWP’s published contract-performance data includes a CMS2012 KPI for technical queries connected with payment problems.
No complete raw error log located
Official publications refer to incidents, audit trails, payment problems, logs and system corrections, but do not publish a complete CMS2012 incident register or known-error database.
Who supports the CMS2012 technology estate?
Official records identify Tata Consultancy Services as a major supplier supporting the core CMS2012 environment.
What can safely be concluded?
Official evidence establishes that TCS is paid for CMS2012 and Child Maintenance technology services and is identified in performance data for application development, maintenance and support.
Individual invoice entries should not be added together and described as the total contract value without checking their accounting basis.
TCS involvement in predictive compliance
Design and build
DWP identifies supplier support involving design, build and assurance.
Live pipelines
The record describes support for live model training and prediction processes.
Logs and screenshots
DWP states that relevant logs and screenshots may be supplied where required to investigate an incident or problem.
Controlled access
The supplier is not described as having routine direct access to live customer information, though controlled diagnostic disclosure may occur.

Evidence-based inference
Operating incident support and contract KPIs normally creates emails, service tickets, change records, meeting notes and closure records. This is an inference from the confirmed arrangements; the complete communications have not been published.
CMS audit-trail systems
Consolidated audit trail
DWP says an Audit Trail process provides a consolidated view of audited user activity to improve detection and deterrence of data misuse.
Oversight teams
Published accounts refer to Management Information and Audit Requirements, Audit Data as a Service, Internal Abuse Monitoring and the Cyber Resilience Centre.
Still not published
The accounts do not provide the full event dictionary, every action recorded, log-retention periods or a direct public method for obtaining case-specific audit entries.
Published CMS errors and system changes
Systems supporting CMS records
CMS2012
The principal operational application for cases under the 2012 statutory scheme.
General Ledger
Client-fund accounts describe accounting information supported by general-ledger and detailed management-information records.
Children Analytical Data Service
Published accounts describe ChADS as part of the analytical and financial-reporting environment.
Potential error points
Where systems exchange, calculate, reconcile or report the same case information, errors can arise from incorrect source data, delayed updates, failed interfaces, duplicated records, rejected transactions or reconciliation differences. This is general systems analysis, not proof of a particular incident.
Data incidents and internal controls
CMS data incidents are recorded
Client-fund accounts include information about DWP personal-data breaches and ICO assessment activity associated with CMS.
Staff access monitoring
The Audit Trail process is described as a control for identifying and deterring inappropriate activity and data misuse.
Records not published in full
CMS2012 incident register
No complete public register was located showing incident dates, severity, affected functions, cause, resolution and customer impact.
Known-error and defect database
The complete list of recognised defects, workarounds, fixes and release versions has not been published.
Root-cause reports
Official case studies describe failures and improvements, but detailed technical root-cause analyses are generally absent.
DWP–supplier communications
Emails, tickets, service-review minutes and incident updates are indicated by support arrangements but are not routinely published.
Complete audit-event dictionary
The public is not shown every event recorded, the fields retained, retention periods or how corrections and deletions appear.
Customer-impact figures
Published data does not provide a complete monthly total of customers affected by each calculation, payment or interface error.
Service credits and penalties
No clear consolidated public record was located of deductions or service credits for failed CMS2012 KPIs.
Release notes and change history
There is no easy public library showing each CMS2012 release, fixed defect and known limitation.
Why this matters
Customers cannot independently assess whether a disputed calculation, missing payment, enforcement action or record change coincided with a recognised technical incident unless relevant logs, change records and audit history are preserved and disclosed.
