Abstract. Technology is becoming increasingly automated, aiming to ease the life of its users. However, besides the advantages of this trend, users are also faced with increasing risks, e.g., regarding their privacy. Examples are seamless online payments that come with the requirement to provide sensitive, e.g., credit card information, or social networks trying to elicit private information for its users. Research on technology acceptance identified two important factors for the individual decision to accept such kinds of risk: trust and personality traits. In this paper we present a model that integrates research findings for personality traits and for trust in the context of technology acceptance. We show that specific personality traits have a distinct direct or moderating effect. We, e.g., found that two personality traits moderate the relationship between perceived ease of use and intention to use. This moderation could explain the inconsistent findings on this relationship in prior research.
To facilitate user-centered software engineering, developers need an easy to grasp understanding of the user. The use of personas helps to keep specific user needs in mind during the design process. Technology acceptance is of particular interest for the design of innovative applications previously unknown to potential users. Therefore, our research focuses on defining a typology of relevant user characteristics with respect to technology acceptance and transferring those findings to the description of personas. The presented work focuses on the statistical relationship between technology acceptance and personality. We apply subgroup discovery as a statistical tool. Based on the statistically derived subgroups and patterns we define the mentioned personas to help developers to understand different forms of technology acceptance. By integrating the specifically defined personas into existing methods in the field of software engineering the feasibility of the presented approach is demonstrated.

Produktqualität ist gekennzeichnet durch das Ausmaß, in dem ein System die zuvor festgelegten Anforderungen erfüllt sowie die impliziten Erfordernisse der diversen Stakeholder befriedigt. Um eine gute Qualität zu erreichen, bedarf es eines erfolgreichen Qualitätsmanagements auf der Grundlage eines angemessenen Qualitätsmodells. Beim Thema Qualität liegt der Fokus häufig einseitig auf den Technologien (u.a. Wartbarkeit, Interoperabilität) und weniger auf den Menschen und den Geschäftszielen. Mit der Norm ISO/IEC 25010-"System and software quality models"-existiert ein internationaler Standard, der neben der technischen Perspektive sowohl die Qualitätscharakteristik Usability als auch Aspekte von "Qualität in der Nutzung" (u.a. Effektivität, Effizienz) thematisiert. Allerdings existieren hierbei ungenutzte Potenziale sowie Widersprüche zu anderen Standards. Der Arbeitskreis arbeitet daher an normierbaren Qualitätsmerkmalen für ein konsistentes Qualitätsmodell.
