Abstract
Activity theory, cognitive ergonomics and distributed cognition are three theoretical frameworks used to understand cooperative work settings. In the past, each has used case studies to describe and defend its point of view. However, comparisons are made difficult by the fact that these studies are usually based on different work settings. This paper describes the application of each framework to exactly the same setting. We believe our approach shows the features that are emphasized and those that are ignored in each framework, enabling us to differentiate their relevant questions. We discuss the effects of a theoretical filter on understanding the work setting, the differences in the concept of activity, the tools and interactions between humans and tools, the concept of representation, and we look at how a plurality of viewpoints may broaden any interpretation.
