National operating model – explainer
The national operating model sets out an approach to rape and serious sexual offences (RASSO) investigations that is victim-centred, suspect-focused and context-led.
The investigator's journey is central to this model and shows how policing can use this approach throughout the investigation.
The materials that support the national operating model show:
- why this change is needed
- how forces can change
- how change can be measured
Victim-centred
Procedural justice principles underpin all officer interactions with victims. Victim rights and needs inform officer decision-making in RASSO investigations.
Suspect-focused
Specialist knowledge about sexual offending behaviour and its impact on victims informs RASSO investigations and offence prevention. Officers are bound to act consistently with the human rights of suspects and victims, as set out in the European Convention on Human Rights (ECHR) and incorporated into domestic law by the Human Rights Act 1998.
Context-led
Officers take the context of the offence into consideration from the moment the offence is disclosed to police.
This includes the:
- victim-suspect relationship context
- victim context, including whether they want an investigation
- suspect context, uncovered through a suspect-focused investigation
Structure of the supporting material for the national operating model
The material is designed with five interconnected layers, which are the:
- vision layer – sets out the overarching aims and objectives of the national operating model, providing a broad, transformational blueprint for action
- flight deck – measurement tools for forces to monitor progress towards the national operating model goals, informing continuous learning and improvement
- strategic layer – turning the vision into a strategic plan, providing policy guidance and actionable steps for realisation of the national operating model aims
- operational layer – provides practical tools, templates and guidance, supporting day-to-day operations and enabling the aims of the national operating model to be realised on the ground
- foundational enablers – offers essential learning resources and guidance for the strategic use of police data
Each layer is relevant to different stakeholders in policing, including investigators, supervisors and senior officers responsible for strategic oversight. The layers of the national operating model are linked and they should be used collaboratively.
Supporting material has information on achieving the vision of the national operating model including:
- strategic plans
- operational tools
- the need for foundational support, such as learning and development
- systemised procedural justice for victims
- effective utilisation of data and digital forensic capabilities
You should explore all layers of the national operating model, even those outside of your role. This will result in a shared understanding with everyone working towards the same aims. By recognising the connections between the layers you can see the impact of strategic decisions on frontline officers, victims and suspects.
Achieving the aims of the national operating model requires coordinated change across every layer and the active involvement of operational officers, senior leaders, police and crime commissioners, other oversight bodies and the public.
Using the national operating model
The investigator’s journey is a 15-stage model investigation strategy from the perspective of an investigator. It offers guidance, legal assurance and consideration points when investigating a case. It shows how RASSO investigations can be victim-centred, suspect-focused and context-led at every stage.
How the new national operating model was developed
The development of the new national operating model involved a comprehensive and collaborative effort between police and academics.
Operation Soteria Bluestone was funded by the Home Office, led by the National Police Chiefs' Council (NPCC) and hosted by the Mayor's Office for Policing and Crime (MOPAC). Operation Soteria Bluestone worked with research team leaders from seven universities, academic experts in various disciplines, experienced professionals in violence against women and girls, and professionals in community sector studies.
The model was refined and informed by evidence-based research and insights gained from the participating pathfinder police forces (Metropolitan Police Service, Durham Constabulary, West Midlands Police and South Wales Police). Operation Soteria Bluestone used a multi-method research approach, including data analysis, case file reviews, observation, interviews, focus groups and document reviews.
