- ZeitschriftenartikelBeware of Performance Indicators(Business & Information Systems Engineering: Vol. 57, No. 6, 2015) Kranz, Tobias T.; Teschner, Florian; Weinhardt, ChristofOnline trading interfaces are important instruments for retail investors. For sound reasons, regulators obligate online brokers to inform customers about certain trade related risks. Research has shown that different behavioral biases can decrease traders’ performance and hence lead to pecuniary losses. The disposition to hold losing stocks too long and sell winning stocks too early (‘disposition effect’) is such a deviation from rational behavior. The disposition effect is analyzed for the prediction market ‘Kurspiloten’ which predicts selected stock prices and counts nearly 2000 active traders and more than 200,000 orders. We show that the disposition effect can be aggravated by visual feedback on a trader’s performance via colored trend direction arrows and percentages. However, we find no evidence that such an interface modification leads to higher activity. Furthermore, we can not confirm that creating awareness of the disposition effect with textual information is suited to decreasing its strength.

- ZeitschriftenartikelIn Search of Information Systems (Grand) Challenges(Business & Information Systems Engineering: Vol. 57, No. 6, 2015) Becker, Jörg; Brocke, Jan; Heddier, Marcel; Seidel, StefanThe paper reports on the results of a Delphi study with 143 information systems (IS) academics that was designed to explore what IS academics perceive to be the grand challenges of the IS discipline. The results provide evidence that the scholarly IS discipline is still much concerned with itself, for instance, in terms of its identity, relevance, foundational theory, or methodological pluralism – suggesting that the old debate on IS identity is not yet overcome. It thus cannot be claimed that the study identifies the grand challenges of the discipline – still it becomes noticeable that the academic community sees potentials for the IS discipline to have societal impact. A total of 21 challenges are identified, of which six challenges are categorized as “meta challenges for further developing the IS discipline” and the remaining 15 challenges are categorized as “IS research challenges” pertaining to socio-technical systems, IS infrastructures, society and ecology, as well as social well-being and affectivity. We provide a ranking of all challenges according to their relevance, potential impact, and possible time frame of realization. The results have some important implications for IS as a discipline as well as its prospective future societal role. It is hoped that through our study we can contribute to the important debate on the challenges of the academic IS discipline.
- ZeitschriftenartikelResearching “Grand Challenges”(Business & Information Systems Engineering: Vol. 57, No. 6, 2015) Mertens, Peter; Barbian, DinaAttempts have been made to identify the grand challenges (GC) in quite different disciplines including Computer Science. These major problems should be solved within one or two generations and the solution would have great societal and economic impact. GCs are to be distinguished from the improvement of methods where the basic problem has already been solved (“emerging fields”). Among other purposes, a common understanding of GCs within a community helps to focus efforts and resources and to create a climate of competition. With our study we try to gain an impression whether a certain consensus is within reach in Business and Information Systems Engineering (BISE; Wirtschaftsinformatik, WI) in the German speaking area. We used a multi-staged opinion survey among scientists and practitioners of WI and could establish an order of precedence concerning the most important GCs. At the top ranks the item “Control of systemic risks in global networks”, followed by “Humanlike Information Systems in business context”, “Determining the influences on the degree of automation und integration”, “Influence of WI on the solution of semantic data processing problems”, and “Overcoming of communication barriers in inter-company integration”. We discuss drawbacks of the GC concept as well as attempts to improve the method. One main problem is to distinguish the terms “grand challenges” (GC), “emerging fields” (EF), and “new research goals” (NR).

- ZeitschriftenartikelInnovation Through BYOD?(Business & Information Systems Engineering: Vol. 57, No. 6, 2015) Köffer, Sebastian; Ortbach, Kevin; Junglas, Iris; Niehaves, Björn; Harris, JeanneLeveraging the IT innovation capabilities of employees is becoming increasingly feasible in the era of IT consumerization. Consumer IT tools, in form of tablets, smartphones, or social media, are entering organizations and are changing the way employees use technology for work. In this article, the authors decipher the term IT consumerization in more detail by providing a framework that illustrates the various perspectives of the phenomenon. They then apply the various perspectives in order to propose an IT consumerization framework that juxtaposes consumer IT with enterprise IT in its ability to lead to individual IT innovation behaviors. Using data from 486 European employees that work for large-sized companies, they are able to infer that consumer IT and the permission to use privately owned IT exert positive effects on employees’ innovation behaviors. An examination of the various perspectives supports the assumption of science and practice that BYOD strategies and the diffusion of consumer IT within organizations are beneficial for innovation. The results provide a first step in theorizing about the innovative power of IT consumerization.
