This paper is a first step towards the structuring and the characterisation of appropriation elements for methodological tools integration. Framework for future research is proposed. The aim of this work is to improve IT provider deployment process, in order that customers better integrate and appropriate methodological tools for design. Research method for this project is given in order to analyse and evaluate existing system, and then to design a "process that enhance tool integration". In this paper, three integration levels are underlined. Nonetheless, it can be noticed that at least two other levels can be analyzed and taken into account. Firstly, in order to lead its customer, the IT provider should firstly appropriate its way of working. It is necessary for provider to well understand their customer internal process. In addition, while the provider company has designed its appropriation strategy, there is an other appropriation level. In fact, provider employees should appropriate this strategy in order to correctly apply it. The provider tools integration process must be design as part of a whole system including its customer. For that purpose, bridges between the deployment process of tools integrator firms and the one of the receiving company may be pointed out. Further research works on specific elements are given. Notably, research will focus on the development of further heuristics for appropriation elements.< Leer menos
