The development of the new National Operating Model (NOM) involved a comprehensive and collaborative effort between police and academics as part of Operation Soteria Bluestone.

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.
