The quality of provided services must be consistent with the output specification and competitiveness. The cost of testing should be paid for by the service provider. Benchmarking/market testing must be based on ‘open book’ accounting procedures.

The payment mechanism is linked to the output specification and performance measurement systems. The first defines the levels and terms under which the service should be provided so that the targets to be met are clearly understood by the contracting parties, whereas the latter sets out the systems and methods to be used to monitor the service being provided by the SPV as required by the procurer.
