The obligation to become more competitive and effective in providing better products and services requires enterprises to transform from traditional businesses into networked businesses. The availability of the Internet and information technologies has encouraged new business strategies that take advantage of enterprises’ ability tocreate networks or to network with other enterprises. One of the challenges faced by a network of enterprises is the development of interoperability between its members, which is highly correlated to the ability to use networked architectures to collaborate efficiently.Traditional methods of Enterprise transformation often focused on designing services inside an enterprise. To our knowledge, there is little focus on interoperability transformations in the context of network enterprises. This emphasises the motivation for the PLATINE project to focus on providing a foundation for understanding, designing and planning transformations with regards to interoperability readiness in a network of enterprises. Transformations in this context are driven by interoperability problems that an enterprise may face. Three kinds of interoperability problems exist: Conceptual barriers, Technical barriers and Organizational barriers. In order to quickly overcome these problems, enterprises need to be prepared to establish means for collaboration and initiate corrective actions before potential interoperability problems occur and be obliged to make unprepared transformations that may be costly and induce unmanageable problems. To this end, an enterprise has to first assess its ability to interoperate. Assessing interoperability allows enterprises to identify their strengths and weaknesses and to prepare the main transformations to deal with, as well as, to prioritize actions that improve interoperability. Many methods are proposed in the literature to deal with interoperability assessment or contribute to it. Unfortunately, current research in enterprise interoperability has largely focused on debating the peculiarities of existing interoperations or evaluating former ones. Very little effort has been made in planning enterprise interoperability. In this project, a prototype of a decision support system, able to diagnose interoperability problems and propose transformations to be put in place, relying on the conceptual framework will be developed. As far as validation is concerned, the practicality of the method and its metrics, along with their acceptance by the industry, will be tested primarily at the Luxembourgish Factory Group. However to ensure a wider visibility and applicability of the results, other players in the service industry realm will be approached.
