This manual has been developed within an Open Method of Coordination (OMC) funded by the European Commission within the 6th Framework Programme. OMC is a European initiative which enhances the exchange between Member States by making recommendations, e.g. 'soft law' measures that can be implemented at European level in the context of the Lisbon strategy. The OMC expert group on policy measures considers public procurement as one of the most powerful instruments to achieve the Lisbon target. Therefore in order to enhance mutual learning, identify good practice, and start joint policy initiatives, including community initiatives, it is important to have an OMC for public procurement.
