Performance Standards must be clearly defined requirements that can be monitored and directly measured by the Contractor and audited by the Authority. It is for the Contractor to propose (and the Authority to agree) how the required Performance Standards will be monitored and reported back to the Authority.
A practical and comprehensive form of performance monitoring needs to be agreed which minimises the potential for disputes and which is not expensive or excessively time-consuming for the Authority or the Contractor.
The parties should take care to ensure that individual Performance Standards are not duplicated.
