4.14 Delays in performing the local intelligence checks required for Enhanced Disclosures arose at some police forces. Some of these delays were partly caused by the quality of information from the Bureau, but variances in the productivity levels of local police forces also caused problems. The Metropolitan Police experienced particular difficulty with the volume of applications because of communication problems between their own computer and that of the Bureau, and in searching their own intelligence systems and recruiting the necessary additional staff. The Agency manages the local police force work under Service Level Agreements. It cannot enforce service standards but has to persuade police forces to meet them. In practice, after some initial difficulties, the Bureau considers that sound relationships have been built and that the processes are now working well.
