This part of ISO 10845 establishes a key performance indicator, in the form of a contract participation goal (CPG), relating to the engagement of targeted enterprises on a contract for the provision of goods, services or engineering and construction works. A CPG may be used to measure the outcomes of a contract in relation to the engagement of targeted enterprises or to establish a target level of performance for the contractor to achieve or exceed in the performance of a contract. This part of ISO 10845 sets out the methods by which the key performance indicator is measured, quantified and verified in the performance of the contract with respect to two different targeting strategies: targeting strategy A and targeting strategy B (defined in Clause 2). NOTE Annex A contains a commentary on the clauses in this part of ISO 10845. Annex B provides guidance on how to develop the targeting data for a procurement document using this part of ISO 10845.
