Thames Valley Violence Reduction Unit Roundtable: Understanding data-led approaches to tackling serious violent crime; Round-up
Overview
The session covered how the TVVRU has overcome barriers to information sharing between public bodies; how the data is being researched and applied; how to share best practice and how industry could help in current and future challenges.
Policy Development; Data and digital systems sharing
The Violence Reduction Units were set-up following the Police, Crime, Sentencing and Courts Act 2022, which mandated that public bodies must share data. This would allow frontline officers cross-public services’ data-flow in order to develop a broader understanding of individuals perpetrating serious cases of violence and apply a public health preventative approach to reducing serious violence.
Policy Timeline
- Serious Violence Strategy 2018; Increases in knife crime and serious violence including homicide from 2014, Need to identify risk and protective factors.
- Serious Violence Duty; Consultation on the Public Health Duty - May 2019, Amendment of section 6(1) of the Crime and Disorder Act 1998.
- Police, Crime Courts, and Sentencing Act[1]; Came into effect 2022, Requirement to produce SNA and Local Plan, Requirement to share data, which is now a Legal Duty.
Platform and Product creation – Thames Valley Together
Through the Thames Valley Together (TVT) Platform, public services across Thames Valley developed a digital space for a centralised and consistent approach to applications of digital technology and databases. This focused on:
- Management; Secure data sharing and collaboration platform, Governance processes and boards, Product management processes, and a single approach for all data.
- Products; Level One Products (Strategic Profiles), Level Two Products (Area/Problem Profiles), Level Three Products (Individual level data).
The system’s database structure and mapping can be seen via;

- Learning from Oxfordshire’s family of prisoners’ data-flows; 2021 saw The Thames Valley Violence Reduction Unit launch its Operation Paramount initiative, introducing a new process to rapidly identify children of a parent who is sent to prison, ensuring they receive the required public service care.
- Interoperability of dataflows between public services; Including access to HMP databases, ensures social care workers have access to criminal records of foster families. Specifically, the Reduction Unit’s digital team has implemented an evidence-based Intervention tracker, which determines the level of success of key decision-making processes via social outcome markers including crime rates and school attendance.
- What next?; The Platform’s next steps can be understood through (1) cultural developments in public services using and adopting best practices in data collection and input, and (2) technical advances within data extraction, collection, storage, and contribution to operations of senior officers’ decision-making. This will allow users to:
- Develop findings from administrative data.
- Ensure data is shared across relevant departments.
- Continued enrichment of TVT to enhance data value and develop spinout platforms e.g. Hot spots, DA Risk, Service, and enhanced decision-making across systems.
- Granular management and communication of risk and prevention.
- Intervention tracker - Cost and return data.
- Develop findings from administrative data.
Day-to-day role of data systems within decision-making
Serana discussed how local interoperable systems operate and the challenges and opportunities they provide and the prospects of working collaboratively with data.
- A topic Serena highlighted was the difference between data and people. The standout challenges were:
- The Challenge of cross-communication, needing to share information sharing that occurs between departments.
- Ensuring individuals are vetted prior to viewing and analysing data.
- The Challenge of cross-communication, needing to share information sharing that occurs between departments.
- lack of technical skills in areas departments and regulating standardisation of data structures;
- Working with community safety to ensure data columns/rows are easy to read. This can be developed through interoperability of data training and technical specialist deployment.
- Working with community safety to ensure data columns/rows are easy to read. This can be developed through interoperability of data training and technical specialist deployment.
- Future of data insights, the main task going forward is to answer questions quickly, including within all key decision-making processes, ensuring better cross-partnership working and the difference in usage of data reference;
- Better dialogue via notification processes is another important aspect, ensuring its measures are communicated fully across departments.
- What does good look like? Sharing best practices across organisations;
- Ensuring individuals don’t fall through the cracks, creating spaces for protecting the data processes of vulnerable citizens. This can be done by ensuring consistent metrics across multiple organisational datasets while developing cross-partnership forums and conferences to share ideas and case studies of success.
