Abstract
Proposed is the foundation of a first-person perspective systems analysis (1ppSA) that utilizes Activity Theory (AT) as diagrammatic resources and phenomenology as a meta-methodology. We exemplify the usefulness of 1ppSA by showing some examples of practicing phenomenological reduction. As mentioned by sociologists, if we can become aware of them, we are liberated from conditions and structures, thereby can have more capabilities of innovations and collaboration for better organizations and information systems. By artificially replacing conditions and structures that we are usually unconscious of by the use of each element of AT diagrams, we can appreciate consistencies and conflicts among the conditions and structures. This means doing eidetic reduction, which results in becoming aware of the conditions and structures.
