Abstract: The open method of coordination (OMC) has introduced a shift with the traditional legal instruments set up by the Treaty. Its introduction was initially supposed to favour more flexibility and openness in the community legal order. After a presentation of the OMC, this article intends to provide an assessment of the OMC's implementation in the ten new Member States. It displays that the OMC is sometimes far from his initial purposes, and in consequence needs to a certain extend, to adapt some of the guidelines and to clarify its legal bases. It concludes with a critical appraisal of the use of the OMC as itself, which should be imbricated in the community.
