The main object of our research is to study the role of the Strategic Information System on the change process. Our first position was a instrumental view. We study the change process according Lewin theory;: the change process is composed by three parts: unfreezing/ change / refreezing phase. We study the role of the SIS on the process change according its relation with the organisation, the dimension of this role ( strategic, organizational ,. . . ), and the function that it can will be in charge. (facilitator,. . . ). Our case study was a very important French Group, we stay in ethnological position, and our observation was during three years. During this long period of case study, two periods were distinct: the first period the case study conform our first suppositions : we observe a technological determinism in the relation between SIS and the organization. But during the last year, the group has some crucial problems, and in this case, the SIS did not have any strategic role in the definition of he management if the crisis and to follow the new strategy. So according to these new events, we had to go back to the theory in order to find new postulates for describing and explaining the new observations. In the end, we chose to study this case with and abductive methodology in order to find better explanations.
