3.2 Individual components and the system as a whole are subject to a rigorous testing regime laid out in the contract. O2 is required to test components and sub components at the factory and on site in four separate testing protocols and to provide certificates of compliance when they have been completed. Once installed, the system is again tested by O2 before being tested by forces in a series of simulated operational settings. PITO developed a number of scenarios for use in the pilot which simulated operational conditions and made use of all the available functions. This was augmented by the input from the Lancashire Police Force during the pilot period in light of their operational experience. The results will be made available to individual forces for their own force acceptance testing. As new functions are developed they will be subject to testing that is equally rigorous. The contract, therefore, contains a provision to ensure that all upgrades and new developments, whether hardware or software, are tested before being accepted and rolled out.
