  Sekulla, A., Giatagantzidis, J., Dax, J. & Pipek, V. (2019)A Lightweight Tool for Measuring the Impact of IT Security Controls in Critical Infrastructures

  doi:10.18420/ECSCW2019_P03
  [BibTeX] [Abstract] [Download PDF]

  IT security is a cost-intensive aspect of SMEs. Critical infrastructures, in particular, are increasingly dependent on good IT security. Increasing security, however, can limit the usability of existing applications and work processes. Based on empirical studies inclusive workshops in the field, we designed a lightweight tool and integrated it into an inter-organizational knowledge exchange platform. With the tool, we want to offer an opportunity to get experience and feedback directly from those employees, who are directly affected by IT security controls. So, the IT security officer can react to it and gain more insight into the impact of IT security controls. They are in the position to administrate the tool’s backend company-internally, while chosen data can be exported and discussed on the inter-organizational platform. Hence, this tool supports a community building effect on organizational and inter-organizational level.

  Ludwig, T., Dax, J., Pipek, V. & Wulf, V. (2017)A Practice-Oriented Paradigm for End-User Development

  IN Paternò, F. & Wulf, V. (Eds.), New Perspectives in End-User Development Cham doi:10.1007/978-3-319-60291-2_2
  [BibTeX] [Abstract] [Download PDF]

  What is end-user development (EUD) and when does a user become an end-user developer? Since the concept of EUD encompasses methods as well as practices of appropriating technology, it is not easy to answer these questions and several researchers already dealt with these issues. Within our chapter we suggest to conceptually extend our understanding of both EUD and the end user (developer). We draw on experiences we gained from past research exploring EUD in practice. We reflect upon the concepts of “gentle slope of complexity,” “tailoring languages” and “appropriation” which we situate within the broader concept of “infrastructuring.” We claim that EUD is given whenever an end user starts modifying the permanent aspects of an application (soft- or hardware) and, thus, starts climbing the tailorability mountain – or in our words, the tailorability staircase – and switching to a higher level to perform a specific practice. In our newly developed terminology this very moment, called “point of infrastructure,” is characterized by a break-down in the current practices which leads an end user to becoming an end-user developer.

  Ludwig, T., Dax, J., Pipek, V. & Randall, D. (2016)Work or leisure? Designing a user-centered approach for researching activity “in the wild”

  IN Personal and Ubiquitous Computing, Vol. 20, Pages: 487–515 doi:10.1007/s00779-016-0935-7
  [BibTeX] [Abstract] [Download PDF]

  Mobile devices have conquered nearly all parts of the daily life. These devices support their owners in specific situations, both at work and in leisure contexts, and therefore make it increasingly difficult to keep work and private life separated. Examining the practices around the use of mobile technology has become a topic of some interest as issues around “work–life balance” emerge. Although the field of HCI provides different approaches for capturing people’s activities in situ, we will show that an additional value can be obtained from a consideration of the “situated” view of contextuality, one which incorporates concerns of privacy and which identifies the reasons people might have for long-term user participation in this kind of study. Despite the undoubted sophistication of existing platforms, the issue of how to provide for dynamic adjustment to meet emerging research questions over time remains challenging. In this paper, we examine how one might approach the design of an observation environment that includes methods for understanding the way of how users reason about research, based upon the context they find themselves in. We have developed a research framework called “PartS,” which captures in situ information about the individual as well as his/her (work/personal) context and offers functionality for collaborative discussions about the information collected. Based on its evaluation, we outline six lessons that need to be considered when designing a study for capturing the subjective context and related activities from an individual user’s as well as a researcher’s perspective.

  Dax, J., Ley, B., Pape, S., Schmitz, C., Pipek, V. & Rannenberg, K. (2016)Elicitation of Requirements for an inter-organizational Platform to Support Security Management Decisions

  10th International Symposium on Human Aspects of Information Security & Assurance, \HAISA\. Frankfurt, Germany
  [BibTeX] [Abstract]

  Due to new regulations energy providers are required to obtain IT security certificates. Especially small and medium-sized energy providers struggle to fulfill these new requirements. Since most of them are in the same situation, we aim to support their collaboration with a platform. We elicited criteria from energy providers how such a platform should be designed to support them. The main contribution is a set of requirements for the collaboration platform along with the implications for its construction. The focus of this work is not on technical innovation but on how existing technologies and best practices can be adopted for the needs of small and medium-sized energy providers.
