It is essential that crime prevention initiatives and security measures are assessed to determine whether they are effective. This may occur in a number of ways, for example through testing existing security measures and processes, auditing of systems and evaluation. Your organisation may use one or all of these methods depending on the size of the company and its security risks. But whatever method you use you need to be able to explain how security measures and crime prevention methods are monitored and evaluated and how the findings are fed back into the strategy. You need to be able to explain how a crime prevention initiative or security measure has been improved based on the findings from an evaluation.
