Investigating the anaesthesiologists' practice through externalist and internalist approaches

摘要

In this paper we present two different stances in analyzing systems: the Internalist and the Externalist approach, which tend to favour different kinds of modelling methods: hierarchical-systemic methods, and flat-ethnographic methods. We advocate that neither are enough for a complete analysis of a work domain in the view of designing effective interventions and predicting their effects, and that a multimethodologic approach is needed. To support this we present two examples of analyses of the anaesthesiologist's work, adopting these two different approaches.
