Towards an Artifact-Oriented Requirements Engineering Model for Developing Successful Products, Services, and Systems: Identification of Model Requirements

Despite extensive research in the domain of requirements engineering (RE), companies still struggle with this discipline. Moreover, practitioners are challenged with developing successful products, services, and systems which address the true needs of their customers. This gives rise to a new research field in the domain of RE, namely artifact orientation. According to the literature, this artifact orientation should increase the success of RE significantly. By conducting a literature review and 7 expert interviews, we identified 7 model requirements (MRs) for an artifact-oriented RE model. Furthermore, the results of this paper suggest that existing artifact-oriented RE models do not sufficiently address all identified MRs. In particular, these models lack the combination of traditional RE practices, such as goal orientation, documentation, and traceability with novel agile approaches. Furthermore, there is a need for a more holistic RE which merges the domains of product, service, and software engineering

Design Requirements for Collaboration Processes to Increase Customer Trust in Mobile Banking Platforms

Banks expect the mobile channel to become more important for collaborating with customers. However, a lack of trust continues to prevent a faster dissemination of such mobile banking services, especially for the private banking customer segment. Hence, this paper discusses various determinants of trust and follows a theory-driven approach rooted in the collaboration engineering methodology. Grounded in the calculativebased, relational-based and institution-based views of trust, we derive the following design requirements for collaboration processes on mobile banking platforms: security, privacy, transparency, familiarity, social presence and normality. By validating these requirements with expert interviews, we contribute to existing theory by adding transparency as a design requirement for a collaboration process that fosters trust. Moreover, contrary to existing theory, we did not confirm familiarity as a requirement in this study

Populationsentwicklung und Habitatpräferenzen der Westlichen Keiljungfer (Gomphus pulchellus Sèlys, 1840) in der Region Basel (Schweiz) : (Odonata: Gomphidae)

Zwischen 2012 und 2014 wurde eine isolierte Population der gefährdeten und national prioritären Westlichen Keiljungfer (Gomphus pulchellus) in den Spittelmattweihern in Riehen (Kanton Basel-Stadt, Schweiz) und zwei benachbarten Fortpflanzungsgewässern untersucht. Die Dichte zum Zeitpunkt der Emergenz betrug zwischen 34,2 und 50,8 Exuvien pro 100 Meter Uferlinie. Der Anteil männlicher Exuvien lag zwischen 42,7 und 54,5 %, während der EM50-Wert zwischen 4 und 12 Tagen schwankte. Die Emergenz begann mit dem Erreichen einer Temperatursumme von 1113,8 ± 69,3 °C (31. Januar bis zum Fund der ersten Exuvie). Die Larven schlüpften überwiegend am südöstlichen Ufer der Weiher und kletterten in über 80 % der Fälle an einer Struktur, mehrheitlich Pflanzenteile von Rubus sp. und Carex sp., hoch. In der benachbarten Kiesgrube Käppelin in Weil am Rhein (Deutschland) wurden nur zwei Exuvien gefunden und in den Entenweihern überhaupt keine. In hauptsächlich sandigem Sediment mit einer Detritusauflage wurden 2014 drei Larven gefangen. Ihre Fundorte lassen auf eine mosaikartige Verbreitung auf der Gewässersohle schliessen. In Substratwahlversuchen bevorzugten die Larven signifikant ein Gemisch aus Fein- und Mittelsand mit Korngrössen zwischen 0,05 und 0,5 mm. Im mit Detritus überdeckten Sediment dauerte das Eingraben der Larven durchschnittlich 36 Minuten verglichen mit 54 Minuten ohne Detritus. Die Spittelmattweiher scheinen das Haupthabitat einer Metapopulation noch unbekannter Grösse zu sein. Zum Schutz und zur Förderung von G. pulchellus wird vorgeschlagen die Gewässer in der Nachbarschaft aufzuwerten, indem bevorzugte Habitatausstattungen eingebracht werden

Mobile contactless payments adoption challenge in the complex network actor ecosystem

Mobile contactless payments (MCP) technology brings an important dual use dilemma where consumer adoption can be halted if consumer is not fully persuaded that the security risk behind the technology use is very low. Currently, although many projects on the implementation of MCP solutions have commenced, MCP is still not picking up. Why? To fill this research gap and better understand how security is affecting MCP implementation, we employ triangulation approach to understand if security is the main obstacle to further adoption and extension of MCP solution. The results reveal that consumer security is the crucial factor in a successful MCP implementation. Our result offers important and new insights for practitioners as it provides a security dimension to consider in the entire contactless payment ecosystem

Is an App Better than an Email? Developing Trust in a Mobile Financial Advisory Service - Design and Evaluation of a Prototype

Private banks see great potential in digital technologies for engaging with clients. Both practitioners and researchers believe that digital technologies, such as mobile applications, increase transparency in the advisory process and consequently raise trust, satisfaction and customer loyalty. This study proposes 5 design requirements (DR) for developing trust in a mobile financial advisory service. A first prototype was designed following the proposed DR. In addition, we conduct an experimental evaluation with 34 participants and compare the prototype with email communication. The findings provide mixed results on how a mobile application, designed according to the proposed DR, could increase trust and intention to use. With regard to overall satisfaction, the app was favored over email communication
