Abstract :
[en] This article presents a methodological approach which helped the software development of an architectural modeler that aims to support the life cycle of buildings with a modular construction system. The modeler assists the building composition processes, the production of useful documents like drawing plans, quantities and specifications, and the evaluation of the thermal performance of the building at any phase of its design. Conducted within a multidisciplinary team of architects engineers, computer engineers and ergonomists, this methodology is based on a constant interaction between the various skills, so that the different perspectives are systematically integrated into the decision process. The methodology is based on the analysis of three fields of functions (composition - production and evaluation) which are considered simultaneously through a theoretical framework stemming from ergonomics: Activity Theory [Engeström 1987].
At first, the software development context is presented. Then, the choice of the Activity Theory as a framework for the analysis will be motivated. The next section relates the multiple concepts of the methodology to each others, in order to identify the principles as well as the inputs and the outputs. Each step in its implementation is then described, followed by the results in terms of the software interface. Finally, the discussion that will follow will consider the contributions and limitations of this methodological approach in the understanding of a system, in order to offer an efficient IT support.
