System analysis has been concerned with as-is or to-be, while is concerned with another aspect in this paper. It is unfavorable to see competing alternatives over the course of IS development activity. Dialectical solutions among alternatives are expected prior to the development. It is constructive to appreciate the similarities and differences of the their constitutive conditions rather than to compare the alternatives. Cultural and historical analysis of organization is required in the early part of systems analysis. However, the method for it is not shared. In this paper, therefore we present a method that uses Activity Theory as a representation method of constitutive conditions and phenomenology as a methodology. We show the method contribute the dialectical solution with an artificial example.
