International audienceThe Before, During and After of a Questionnaire – The Case of the COI-TIC 2006 Survey: This study focuses on the elaboration of a questionnaire for a large-scale survey on organizational changes and communication technologies. Preparatory meetings were observed, and then studies using the gathered data were consulted. It is a question of reporting the main considerations at the origin of the construction of the questionnaire. These considerations are above all pragmatic, dependent on the experiences and knowledge of the designers. Strategies are negotiated, but the resulting agreements are precarious. Collective work to collect responses is structured by the instrument and guided by some objectives, all of which allows the possibility of multiple redefinitions of the data, with little concern for what was done during the preparatory work
