This chapter describes research in progress on the philosophical concept of authenticity – used as a framing device for providing an interpretation of aspects of both ethical and practical action on the part of information systems (IS) professionals. Ethical codes and prescriptive IS development methods for IS professionals can be found in most developed countries in the world. Here it is argued that ethical codes and IS methods may be of limited value in IS work. One key problem here is that IS analysts and designers have to intervene in organisations (and thereby intervene in the lives of the members of those organisations). It is argued that an important issue for IS research is whether they choose to do so in (what will be characterised as) an authentic manner, rather than doing so in sincere adherence with either a code of professional ethics or with a series of methodological precepts.
