It has been critically evaluated by many IS researcher that the traditional IS design methodology represented by 'waterfall model' does not necessarily fit to the unstable business environment, because these treats the IS as a self-contained existence, and depends on dualism, such as 'environment-and-organization' or 'environment-and-action'. Therefore, there are quite a few views that IS design methodology must be reexamined under the logic of subject-and-object unification, the interrelationship with environment, the viewpoint of socio-technology, and so on. One of the countermeasures is to reconsider the IS function and then to re-develop the design methodology from the viewpoint of a situated action theory. In this paper, firstly, the significance of IS design informed by a situated action theory is clarified by the survey of related precedence research. Subsequently, by reinterpreting the existing case study from a situated perspective, the validity of situated design methodology is verified, and the clue for building situated design methodology is discovered.
