Abstract
Business professionals are expected to practice systems analysis in an ever-changing environment. However, there are no methods they can directly appropriate for systems analysis of a first-person perspective (1ppSA). It is known that the conventional systems analysis with some user participation is based on naive philosophy while 1ppSA is on phenomenology. Although systems analysis requires diagrammatic expression, phenomenology does not have any diagrammatic resources. As a part of a project that we develop a 1ppSA method by appropriating activity theory that has diagrammatic expressions, we investigated whether activity theory satisfies the requirements for methods and attitudes that phenomenology poses.
