Narrative Transformation is a method for clarifying the purposes and functionality of IT work means in groups of designer-users with self-selected membership. This includes that interests are clarified and pursued. Narrative Transformation has been developed specifically for groups in which the members themselves are largely responsible for setting up their own work situation, organization and work means (e. g. associations of freelancers, communities of researchers). As part of the interest guided development process the participants identify things they have taken for granted; they explore if it is justified to take them as »matters of course«; if not, they develop more appropriate notions. The procedure of Narrative Transformation comprises diverse steps. Every participant individually writes episodes describing events that occurred to them, and that they think highlight important aspects of the work setting that is to be changed by IT means. Then the participants collectively »search« their episodes for »matters of course«. The »search criteria« are developed as part of this process. The participants explore how appropriate the assumptions in the episodes are and develop new, more appropriate notions, if necessary. This corresponds with forming and discussing hypotheses regarding: (1) characteristics of the participants' settings, conditions, situations and constellations; (2) specific relations between possibilities and restrictions for fulfillment that »are contained« in them; and (3) changes -especially in terms of work means and practices -that are beneficial. The participants examine their hypotheses in their every-day life/work settings, and their according experiences are fed back into the Narrative Transformation group process, where they can serve as impulses for further processes of reflection and change, possibly using Narrative Transformation. Narrative Transformation is based on notions of Activity Theory, and here especially the research direction of Critical Psychology, such as the specific notions of agency, (inter-) subjectivity, purpose, meaning, objectification and appropriation. The procedure of Narrative Transformation itself is an elaboration of the procedure of Memory Work.
