Abstract EN:
The research has tried to understand why using the same information system development method, one can be led to success or failure. The study has been grounded on practical investigations in different organizations. The observation are confronted with three theories, found in the litterature, which have proposed contingency factors, related to the project or its context. According to the authors, the right method to be selected and the way of implementing have to fit with those factors. The research has showed that there is in fact three processes, which have to be managed in a consistent way: production, decesion and change. Methods usually focus on the production proces, whereas implementing successfully a method on a project implies to control simultaneously decision taking, attitude changes and production activites. It is precisely this control which requires to be fitted with the characteristics of the project.
Abstract FR:
Le but de la these est de mener une reflexion, a partir d'observations en entreprise, sur les causes d'echec ou de succes dans l'utilisation d'une methode de developpement de systeme d'information automatise. Les observations sont confrontees a trois theories proposant des facteurs de contigence, caracterisant le projet ou son contexte, qui appellent une reponse methodologique adaptee. Les resultats de la recherche ont mis en evidence l'existence d'un triple processus: production, decision et changement. Les methodes se focalisent generalement sur le processus de production, alors que la mise en pratique oblige, pour que la demarche aboutisse, a piloter simultanemenbt les prises de decision, les changements de comportement et les activites de production. C'est ce pilotage qui requiert une adaptation aux caracteristiques du projet.
