  Rohde, M., Brödner, P., Stevens, G., Betz, M. & Wulf, V. (2017)Grounded Design – a praxeological IS research perspective

  IN Journal of Information Technology, Vol. 32, Pages: 163–179 doi:10.1057/jit.2016.5
  [BibTeX] [Abstract] [Download PDF]

  In this paper, we propose Grounded Design – a particular design research (DR) approach rooted in a practice-theoretical tradition. It assesses the quality of information technology (IT) design through evaluation of emerging changes in social practices, which result from the appropriation and use of IT artifacts. The paper starts with a systematic analysis of the reasons for persistent limitations of traditional information systems DR, specifically in coping with problems of contingency and self-referentiality. Following this critique, the principles of Grounded Design are presented. Grounded Design is applied in case studies where we reconstruct the social practices observed before and during the design and appropriation of innovative IT artifacts. We call these context-specific research endeavors ‘design case studies.’ In conducting these case studies, Grounded Design builds upon well-established research methods such as ethnographical field studies, participatory design and action research. To support the transferability of its situated findings, Grounded Design suggests documenting increasing numbers of design case studies to create an extended, comparative knowledge base. Comparing cases allows for the emergence of bottom-up concepts dealing with the design and appropriation of innovative IT artifacts in social practice.

  Betz, M. & Wulf, V. (2014)EmergencyMessenger: A Text Based Communication Concept for Indoor Firefighting

  IN Proceedings of the 32Nd Annual ACM Conference on Human Factors in Computing Systems, Pages: 1515–1524 doi:10.1145/2556288.2557188
  [BibTeX] [Abstract]

  Finding and rescuing missing or injured people or fighting fire inside burning buildings is a central challenge for fire brigades. To ensure the safety of indoor work, monitoring the operations of firefighting units is crucial. As in most countries, firefighters in Germany utilize radio sets to establish voice communication between indoor operating units and the supervisory structure outside. Based on findings from a long term ethnographic study in cooperation with different German fire brigades over a time span of more than 5 years we analyzed the advantages and disadvantages of the current voice over radio communication tactics and techniques. We designed and evaluated a complementary text based communication device the EMERGENCY-MESSENGER to support the time critical work of indoor units working under harsh conditions, wearing Self-Contained-Breathing-Apparatus (SCBA). We conducted 13 full scale training missions including extensive debriefings to design and evaluate the communication concept and the corresponding device.

  Ramirez, L., Dyrks, T., Gerwinski, J., Betz, M., Scholz, M. & Wulf, V. (2012)Landmarke: An ad hoc deployable ubicomp infrastructure to support indoor navigation of firefighters

  IN Personal and Ubiquitous Computing, Vol. 16, Pages: 1025–1038 doi:10.1007/s00779-011-0462-5
  [BibTeX] [Abstract]

  Indoor navigation plays a central role for the safety of firefighters. The circumstances in which a firefighting intervention occurs represent a rather complex challenge for the design of supporting technology. In this paper, we present the results of our work designing an ad hoc ubicomp infrastructure to support navigation of firefighters working in structure fires inside the zone of danger. We take a wider approach, complementing the technical questions with the development of effective navigation practices based on technology available today. We provide an overview of the complete design process, from the theoretical and empirical underpinnings to the construction and evaluation of three iterations of the platform. We report the results of our evaluation and the implications and tensions uncovered in this process, and we discuss the challenges and implications of it for the design of ubicomp for firefighters.
