The Authority is starting in the right place

1.11 Figure 4 is a basic maturity model which sets out some of the key characteristics of an effective central assurance system. There first need to be mechanisms to enable control over the system, which can then be supplemented by those which allow the system's performance to be measured. When fully mature, feedback mechanisms will be used to continuously improve how the assurance system operates.

1.12 Given that the Authority has only existed since April 2011, it would be unreasonable to expect the new assurance system to be fully mature. However, the steps that have been taken so far have enabled it to progress in the right direction. The Prime Minister's mandate for assurance is a necessary starting point to help the Authority secure the coordination and cooperation that is required from departments and HM Treasury. The Authority has used the mandate to collect project data and to require integrated assurance and approval plans from departments, to understand what type of assurance is required and when.

1.13 In order to enable the system to continue to mature, these processes need to be built to last. There need to be strong links between the bodies in the system, with close cooperation. Processes need to be formalised, and sufficient resources must be available, to avoid the system becoming overdependent on key individuals. Regular transparent reporting of performance is particularly important in embedding the system, encouraging cooperation by highlighting the system's successes as well as any instances of non-compliance.
