Time for a "design turn" in IS innovation research? A practice report from the home front

Purpose - In contrast to the behavioural paradigm of IS research, design science seeks to develop a body of practically-oriented knowledge which will directly aid the design, implementation, and use of information technologies and systems. Design science, however, remains a minority practice. The purpose of this paper is to argue the case for its more widespread adoption, especially so in research on innovation. Design/methodology/approach - To this end, the authors report an example of design science in action. Two experiments are reported, both concerning the design of the user interface for domestic heating systems. Of note is the use of a medium-fidelity laboratory simulation ("microworld") in this work. Findings - Two specific substantive findings results. First that ecologically designed feedback, embodying a strong mapping between task goals and system status, produces superior task performance. Second, that predictive decision aids provide clear benefits over other forms of user support, such as advisory systems. Practical implications - Whilst arguing the general case for design science, the study shows that there are formidable barriers to its wider promulgation. These include the challenges of constructing realistic meta-artefacts, compounded by the complex, modal and uncertain nature of design theory itself. The practical value of the microworld paradigm is also confirmed. Originality/value - Although research in this field has largely addressed the workplace, here the paper addresses the domestic realm. Further novelty derives from the use of the microworld approach. The argument that design science should draw more on the proven methods of "good design" (e.g. prototyping, user participation) in terms of its own praxis is also noteworthy.
