The public purchaser establishes a methodology for tender assessment. The criteria for assessment include (i) a set of criteria determined by the public purchaser, linked to the nature and to the details of the contract and (ii) a set of non-discriminatory criteria linked to the subject of the market.

Furthermore, the technical specifications must be determined before any call for tender takes place, or any negotiation, thus guaranteeing the quality of services and the goods which are provided by the contract.
