The barrier model approach is utilised to examine complex forms of crime by focusing on the logistical process underpinning it. The barrier model approach starts by scrutinising the crime script and the logistical model utilised by the criminals to commit a crime. Utilising crime scripts allows for the identification of logistical process steps. A script accurately depicts the events, procedures, and steps criminals follow when committing a crime. It includes both preceding and subsequent events.
The employment of the barrier model enhances the investigative process by focusing on administrative and financial aspects of criminal activities. Government stakeholders have acknowledged its pivotal role in countering serious and organised crime.
