Management by Objectives-Based Groupware: Requirements for Efficient and Effective Achievements of Objectives
(2011)
- This paper is concerned with the challenges arising from the development of a groupware requirement specification for effective and efficient achievement of operative and strategic objectives in mass production industry. To analyze the process by which objectives are achieved, a systematical investigation using document analysis, participant observation, interviews and context scenario analysis was undertaken at a large manufacturing location with over 6 000 coworkers of a multinational automobile supplying company. The results of this in-depth analysis of objective achievement were utilized to develop a detailed requirement specification for a management by objectives groupware for use in mass production industry.

Dialogentwurf
(2012)
- Der Dialogentwurf ist die Festlegung, wie die Benutzungsschnittstelle gestaltet sein soll. Dabei werden die Benutzeranforderungen und –wünsche in ein konzeptionelles Modell überführt. Das konzeptionelle Modell ist die Beschreibung des vorgeschlagenen Software-Systems als Festlegung der integrierten Ideen und Konzepte bezüglich seines Verhaltens und seines Aussehens.

Gemeinsam einig: Partizipation in Gruppenempfehlungssystemen
(2012)
- Gruppenempfehlungssysteme unterstützen Gruppen bei der gemeinsamen Auswahl von Aktivitäten oder Produkten. Neben der Generierung von Empfehlungen wird der gezielten Unterstützung der Gruppeninteraktion während der Aushandlung in der einschlägigen Literatur eine Schlüsselstellung zugeschrieben. Dieser Beitrag stellt drei alternative Konzepte zur Gruppenentscheidungsunterstützung vor, berichtet über eine Benutzerstudie und leitet Gestaltungsanregungen ab.

Informing the Design of Group Recommender Systems
(2012)
- In this paper we present a literature study on social psychological concepts, which informs the design of group recommender process models in group recommender systems. We matched core concepts to well-established factors influencing satisfaction in groups, and obtained three most relevant social psychological concepts: group identification, group norms, and social roles.

RobustTrav: NAT Optimisation for the RobustCooperation Suite
(2012)
- Cooperative systems supporting remote teams are based on distributed software architectures. Underneath most of these architectures is the Internet Protocol version 4 (IPv4), which acts as technological backbone. Despite its strengths, the IPv4 also entails challenges for developers of such systems for getting system messages through firewalls without increasing latency and bringing delays for users. In this paper we introduce the RobustCooperation Suite for communication, coordination, and collaboration, as well as its RobustTrav mechanism for effective and efficient NAT traversal.

SCTA Tracer: A Distributed Environment for Standardised Awareness Support Assessment
(2012)
- Awareness support in cooperative environments has been a research issue in the area of distributed systems for computer-supported cooperative work for more than two decades. Measuring its effectiveness remains a complex task since it is difficult to grasp awareness in situ. Consequently, techniques and tools are required generating results while a user’s awareness is still present. The Standardized Coordination Task Assessment (SCTA) and its tool the SCTA Tracer use freeze probes to query participants at specific points in time while working on a common task measuring and recording response times, performance, and errors. The result is visualized in a four quadrant system distinguishing illusive, ineffective, inefficient, and ideal systems. The SCTA Tracer guides awareness support researchers and designers to focus their effort on essential concepts already at early development stages. This paper shows how a smart selection of tools and techniques is integrated for this complex task.
