“…Nakakawa et al propose a theoretical model on group architectural decision making for enterprise software systems [51]. Sousa et al present a process for group architectural decision making, in which a facilitator helps the group interactions [52]. In this paper, the proposed GADGET process does not require a facilitator, while our focus is on presenting empirical evidence on the GADGET process.…”

Context: Many software architectural decisions are group decisions rather than decisions made by individuals. Consensus in a group of decision makers increases the acceptance of a decision among decision makers and their confidence in that decision. Furthermore, going through the process of reaching consensus means that decision makers understand better the decision (including the decision topic, decision options, rationales, and potential outcomes). Little guidance exists on how to increase consensus in group architectural decision making.Objective: We evaluate how a newly proposed process (named GADGET) helps architects increase consensus when making group architectural decisions. Specifically, we investigate how well GADGET increases consensus in group architectural decision making, by understanding its practical applicability, and by comparing GADGET against group architectural decision making without using any prescribed approach.Method: We conducted two empirical studies. First, we conducted an exploratory case study to understand the practical applicability of GADGET in industry. We investigated whether there is a need to increase consensus, the effort and benefits of GADGET, and potential improvements for GADGET. Second, we conducted an experiment with 113 students from three universities to compare GADGET against group architectural decision making without using any prescribed approach.Results: GADGET helps decision makers increase their consensus, captures knowledge on architectural decisions, clarifies the different points of view of different decision makers on the decision, and increases the focus of the group discussions about a decision. From the experiment, we obtained causal evidence that GADGET increases consensus better than group architectural decision making without using any prescribed approach.Conclusions: There is a need to increase consensus in group architectural decisions. GADGET helps inexperienced architects increase consensus in group architectural decision making, and provides additional benefits, such as capturing rationale of decisions. Future work is needed to understand and improve other aspects of group architectural decision making.

“…Studies that involve design patterns and report on experiences of success that could inspire other social contexts, such as that of Brazil, are still scarce. Some authors have previously identified a list of usability patterns for specific iDTV interactive tasks [19]. The pattern collection used in this work was proposed by Kunert [11] with a focus on interaction design for iDTV applications and special attention to usability issues.…”

Interactive Digital TV (iDTV) is an emerging technology in Brazil, with inherent characteristics that must be addressed and which demand technical resources and references to support the design and development of interactive applications. This paper presents a design activity that reports and discusses the use of specific design patterns combined with prototyping tools and techniques inspired by Participatory Design in the design of applications for iDTV. Results are presented and discussed focusing on: the advantages of using design patterns in a participatory design, the main difficulties the groups had during the design activities, the importance of tools to support the design of iDTV applications.

“…On the one hand, contributions such as UPi [9] or DIANE+ [10] propose extensions of existing methods (the Rational Unified Process [8] or MERISE -a development method mostly used in francophone companies) that address specifically user interface design. In terms of actors, these methods involve HCI and/or usability experts, but to the best knowledge of the authors, while UPi is described as a RUP discipline, no indications on how DIANE+ should be integrated into its host method is given.…”
