Analyse des systèmes d'interactions à l'oeuvre au sein d'un projet TI : mise en évidence d'une perspective dynamique et relationnelle

Our study seeks to deepen understanding of the outcome of IT projects (success or failure) by examining the active role of the objects involved (in particular, technology) and their interaction with humans taking part in the project. With this in mind, the article sets out to lay a cornerstone in this domain by answering the following two questions: a) How should interactions between actors and technology be analysed in terms of the relational ontology of a specific IT project, in accordance with the principles of ANT? b) To what extent does this new analytical approach provide an explanation of the results obtained? The product in question is an IT project for the industrialisation of a technology (Virtual Desk) that ultimately ended in failure (the project was abandoned). To answer these questions, we propose a method of visualising the project based upon network analysis derived from actor-network theory (ANT). This method for observing IT projects was applied in real time during the course of a longitudinal study concerning the Virtual Desk. Our study yielded two contributions. The first, which is theoretical, involves the discovery of a mode of operationalisation of ANT allowing improved reading and understanding of the outcome of IT projects and helps explain the limitations of its operationalisation in ontological terms. The model developed facilitates analysis of dynamic interactions between the various entities involved in the project, thereby allowing an understanding of the development of the network along a convergent/divergent continuum. It demonstrates the need to abandon an approach based on linear cause-and-effect chains while underscoring the need to create and maintain "technological symbiosis" between humans and non-humans in order to promote a successful outcome for IT projects. The second contribution, which is methodological, is consistent with recent studies aimed at improving the cartography of controversies, and proposes a first method of viewing (graphics) socio-technical networks as well as their development
