The 2015 PCR clarified the rules on framework agreements as follows: a framework agreement is needed to meet the paper needs of a number of authorities over a four-year period. Following the opinion of the Official Journal of the European Union and the selection procedure based on financial and economic capacity and technical capacity, the offers will be evaluated on the “economically most advantageous” basis to enter the framework. A number of suppliers are involved in the framework to provide a variety of types of paper – simple, fed, recycled, colorful, etc. – over a four-year period. The Authority addresses the supplier in the framework whose offer is “economically the most advantageous” on the basis of the initial allocation criteria for each call required during the four years. Since the conditions do not need to be refined or supplemented in this case, the Authority does not need to use the mini-competition option. These examples are taken from the Office of Government Commerce`s “Framework Agreements and Community Developments” document: a framework agreement is not an interim agreement. It is more detailed than a statement of principle, but less than a full-fledged contract. Its aim is to find the fundamental compromises necessary to enable the parties to develop and conclude a comprehensive agreement that ends the conflict and creates lasting peace.  In the public sector, there are a number of central public procurement entities whose objectives are the creation and management of framework agreements in accordance with EU public procurement directives  and which are available for use by designated public bodies. In the United Kingdom, for example, crown commercial service, municipal consortia such as Eastern Shires Purchasing Organisation (ESPO) and Yorkshire Purchasing Organisation (YPO) and consortia, in the areas of higher education and training: APUC (in Scotland), Crescent Purchasing Consortium (CPC),  London Universities Purchasing Consortium (LUPC), North Eastern Universities Purchasing Consortium (NEUPC),  North Western Universities Purchasing Consortium (NWUPC)  Framework agreements continue to play a central role in public procurement, including the possibility of cooperation between councils through purchasing centres.
