The Derek Cornish Crime Script Analysis Model breaks crimes into sequential steps, from preparation to completion. It helps investigators understand offender actions, identify intervention points, and disrupt criminal processes, supporting prevention strategies, situational analysis, and targeted investigative planning across different crime types.
The National Intelligence Model (NIM), developed by UK National Police, provides a structured approach to intelligence-led policing. It integrates data collection, analysis, and decision-making to prioritise threats, allocate resources, and support strategic and tactical operations, enhancing effectiveness in crime prevention and investigative processes.
The Jerry Ratcliffe 3i Model (Interpret, Influence, Impact) supports intelligence-led policing by linking crime analysis to decision-making. It helps investigators interpret data, influence operational responses, and assess outcomes, ensuring intelligence is effectively used to guide strategies, reduce crime, and improve policing and investigative performance.
The Herman Goldstein SARA Model (Scanning, Analysis, Response, Assessment) provides a structured problem-solving approach in policing. It helps investigators identify recurring issues, analyse causes, implement targeted responses, and evaluate effectiveness, supporting proactive crime prevention, community policing, and evidence-based decision-making in investigative and operational environments.
The Derek Cornish and Ronald V. Clarke Criminal Decision Process Model analyses how offenders make decisions before, during, and after crimes. It examines rational choices, risks, rewards, and situational factors, helping investigators understand behaviour, anticipate actions, and develop effective prevention, profiling, and investigative strategies.
The Lawrence W. Sherman Hot Spot Policing Model focuses on identifying and targeting high-crime areas where offences cluster. By concentrating police resources in these hotspots, it enhances deterrence, disrupts criminal activity, and improves public safety, supporting data-driven decision-making and effective deployment strategies in modern investigative and policing environments.
