    • 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.

      [BibTeX] [Abstract] [Download PDF]

      Living Labs provide a human-centric’ research approach for the design of new ICT artefacts. In Living Labs users participate over several design stages, providing insights into unexpected ICT use, co-creation and evaluation of new IT solutions. Although this approach is becoming more popular, there is little comparative and reflective work on its practical dynamics, problems and possibilities. In this study, we analyse two 4-year Living Lab projects in Lancaster, UK and Siegen, Germany within the domain of Social TV, and compare experiences. We focus on documenting the purposes, methods and user dynamics that affect the trajectory of such long-term research initiatives, focusing inter alia on the dynamics of researcher/user interaction and the developing issues of trust and managing expectations; emphasizing some often neglected ethical issues and the impact of users’ individual characteristics and their role in the community dynamics of Living Labs.

    • Ley, B., Ludwig, T., Pipek, V., Randall, D. D., Reuter, C. & Wiedenhoefer, T. (2014)Information and Expertise Sharing in Inter-Organizational Crisis Management

      IN Computer Supported Cooperative Work: The Journal of Collaborative Computing (JCSCW), Vol. 23, Pages: 347–387 doi:10.1007/s10606-014-9205-2
      [BibTeX] [Abstract] [Download PDF]

      Emergency or crisis management, as is well-attested, is a complex management problem. A variety of agencies need to collaborate and coordinate in real-time and with an urgency that is not always present in other domains. It follows that accurate information of varying kinds (e.g. geographical and weather conditions; available skills and expertises; state-of-play; current dispositions and deployments) needs to be made available in a timely fashion to the organizations and individuals who need it. By definition, this information will come from a number of sources both within and across organizations. Large-scale events in particular necessitate collaboration with other organizations. Of course, plans and processes exist to deal with such events but the number of dynamically changing factors as well as the high number of heterogeneous organizations and the high degree of interdependency involved make it impossible to plan for all contingencies. A degree of ongoing improvisation, which typically occurs by means of a variety of information and expertise sharing practices, therefore becomes necessary. This, however, faces many challenges, such as different organizational cultures, distinct individual and coordinative work practices and discrete information systems. Our work entails an examination of the practices of information and expertise sharing, and the obstacles to it, in inter-organizational crisis management. We conceive of this as a design case study, such that we examine a problem area and its scope; conduct detailed enquiries into practice in that area, and provide design recommendations for implementation and evaluation. First, we will present the results of an empirical study of collaboration practices between organizations and public authorities with security responsibilities such as the police, fire departments, public administration and electricity network operators, mainly in scenarios of medium to large power outages in Germany. Based on these results, we will describe a concept, which was designed, implemented and evaluated as a system prototype, in two iterations. While the first iteration focuses on situation assessment, the second iteration also includes inter-organizational collaboration functionalities. Based on the findings of our evaluations with practitioners, we will discuss how to support collaboration with a particular focus on information and expertise sharing.

      Große Stromausfälle, wie beispielsweise der Ausfall der Stromversorgung im Nordosten der USA (2003) oder der Ausfall in weiten Teilen von West-Europa (2005), machen die fundamentale Bedeutung von Strom in unserem täglichen Leben deutlich. Sie zeigen auch, welche wichtige Rolle die Kooperation und Zusammenarbeit zwischen allen Beteiligten der Bewältigungs- und Wiederherstellungsarbeit spielt.

      This paper presents approaches on how to deal with terminological ambiguities (different understandings of terms in heterogeneous groups of actors) in collaborative systems. First we will give some insight on the conceptual and theoretical foundation surrounding the ‘triangle of reference’, a model of how linguistic symbols are related to the objects they represent. Then we will describe the results of our exploratory empirical study, which was conducted in Germany, and dealt with inter-organisational crisis communication. Based on this, we will then deduce requirements necessary for supporting and dealing with terminologies, and propose technical approaches for collaborative systems.

      [BibTeX] [Abstract]

      Studying domestic usage contexts has become an important field in research. Recent technological improvements have made media available on different devices, in different contexts and from different places. The adoption and appropriation of new devices and technologies has led to a more flexible usage behavior. However, even if we know about such a behavior, many questions, regarding how new technology changes the user’s media usage and how these changes affect the social structure in a household, are still unanswered. We will address this topic in our work and want to provide an insight on how recent media consumption patterns have changed due to the appropriation of new technologies in the home. Based on a qualitative long-term Living Lab study we will present various patterns based on changes in media usage routines and their influences on households as social systems. The results provide a detailed understanding of how the new technology is embedded within domestic life by considering potentials and conflicts that also address further design oriented work.

      Improvisation is necessary when planned decision-making as the main managerial activity does not fit the conditions the practice provides. In these cases, information technology should not just automate planned and structured decisions, but support improvisational practice. In this contribution we present an empirical study about the improvisation work in scenarios of medium to large power outages in Germany. Our focus is on inter-organizational cooperation practices, thus we examined the cooperation of fire departments, police, public administration, electricity infrastructure operators and citizens. Our empirical material allows to describe reasons and conditions for improvisation. Our resulting recommendations address the support of aggregation and visualization of information, a necessary individualization of information compositions, options for collaborative situation assessment, requirements for informal and formal communication, and accessibility of information resources.

      To assess current situation properly is crucial for effective decision-making in crisis management. However, gathering accurate information from incidence sites and providing appropriate support for assessment practices faces several challenges. The unique information demands of each crisis situation, the information availability or inter-organizational problems and obstacles to information exchange are important factors that need to be considered in designing ICT. In this contribution we present results from an empirical study about decision-making practices in scenarios of medium to large power outages in Germany. We focused on the needs and practices on information exchange at the level of inter-organizational cooperation. We examined the cooperation of fire departments, police, public administration, electricity infrastructure operators and citizens. Our empirical material reflects particularly conditions and challenges in current situation assessment practices, and we were able to derive some design requirements for an inter-organizational situation assessment client (ISAC) as a complementary tool for the crisis management infrastructures the individual organizations have already build for their own areas of responsibility: Support for the aggregation and visualization of information, for the individualization of information compositions, for a collaborative situation assessment and for appropriate structures for sharing and accessing information resources.

      Major electricity breakdowns like the Northeast Blackout (USA) in 2003 or the blackout in most parts of Western Europe in 2005, have shown the fundamental role of electricity in our everyday life. The experiences of these accidents show that power suppliers, firefighters, police, county administration and citizens face multifarious challenges in inter-organizational communication, information and coordination processes during coping and recovery work. In this work-in-progress paper we describe early research dealing with inter-organizational issues in emergency management (EM). We are mainly focusing on supporting social practices in inter-organizational EM, for example collaborative interpretation of emergency situations, ad-hoc coordination or supporting citizen communication and helping routines. Identified from our experiences from related projects, discussions and literature studies, we suggest potential questions and future topics in user-driven software engineering processes for EM and domain specific problems, such as supporting citizen participation, coping with information uncertainties and quality variations or enhancing inter-organizational learning.

      Major electricity breakdowns like the Northeast Blackout (USA) in 2003 or the blackout in most parts of Western Europe in 2005, have shown the fundamental role of electricity in our everyday life. The experiences of these accidents show that power suppliers, firefighters, police, county administration and citizens face multifarious challenges in inter-organizational communication, information and coordination processes during coping and recovery work. In this work-in-progress paper we describe early research dealing with inter-organizational issues in emergency management (EM). We are mainly focusing on supporting social practices in inter-organizational EM, for example collaborative interpretation of emergency situations, ad-hoc coordination or supporting citizen communication and helping routines. Identified from our experiences from related projects, discussions and literature studies, we suggest potential questions and future topics in user-driven software engineering processes for EM and domain specific problems, such as supporting citizen participation, coping with information uncertainties and quality variations or enhancing inter-organizational learning.

(2010)InfoStrom: Learning information infrastructures for crisis management in case of medium to large electrical power breakdowns.

      One of the most important infrastructures in modern industrialized societies is the electricity network. Due to its fundamental role for many aspects of our everyday life, power infrastructures manifest a strong dependence between power suppliers and customers. Customers take the infrastructure for granted; it appears mostly invisible to them as long as it works, but in the case of breakdowns in power supply customers become aware of the dependence on electricity. They join professional actors in the recovery and coping work with regard to the electricity breakdown: Maintenance workers of the power provider, police, firefighters, red cross, etc. These institutions are professionalized for dealing with such situations, but the people affected by a power outage also need to be considered as actors.
