The National Intelligence Model (NIM) in the United Kingdom (UK) by which the Norwegian strategy was stimulated, is a business model for law enforcement. It became the policy of the Association of Chief Police Officers (ACPO), and many forces underwent major restructuring and were allocated new resources in order to implement it. NIM takes an intelligence-led approach to policing. The UK Government acknowledged its benefits, and all forces in England and Wales were required to implement NIM to national minimum standards from 2004. NIM consists of nine individual elements: Crime Pattern Analysis, Market Profile, Demographic/Social Trend Analysis, Criminal Business Profile, Network Analysis, Risk Analysis, Target Profile Analysis, Operational Intelligence Assessment, and Results Analysis; all elements are discussed in detail. To implement such a model locally requires local strategy work, as indicated by the South Yorkshire strategy. To measure the extent of implementation, the research model suggests three alternative definitions. In empirical research, the situation will determine which ones are appropriate for implementation measurement. Variation in the extent of implementation from police district to police district is explained in the research model by three factors: national agency support, local police readiness, and environmental support. The unit of analysis is the police district, implying that there will be variation in support from the national agency to different police districts. Figures and references
