Impacts of Reputation for Quality on Company Responsibility and Product-related Dangers in times of Product-recall and Public Complaints Crises: Results from an Empirical Investigation (2011)
Grunwald, Guido
This research paper analyzes the role of pre-crisis reputation for quality on consumers ’ perceptions of product-related dangers and company responsibility in product-harm crises with varying risk information. We consider (non-) substantiated public complaints incorporating low and moderate product- related risks, as well as product-recall situations involving serious risks to the health and safety of consumers. Hypotheses are derived from theories and concepts of consumer behavioural psychology. These are then tested empirically by using an online experiment. The effects of reputation are analyzed across different crises contexts to derive some general insights useful for crisis management. In order to shed light on situational differences of the reputation mechanism its effect on individual crisis level will also be considered. In general, the analysis fi nds that reputation for quality is capable of positively infl uencing the perceptions of company responsibility and thereby shielding the manufacturer from receiving blame. However, an established reputation for high product quality prior to the crisis fails to positively impacting consumers ’ perceptions of problem severity. The crisis-specifi c effects of reputation turn out to be ambivalent. On the basis of these fi ndings, recommendations to crisis managers and relevant avenues for future research are derived.
Adapt Cases: Extending Use Cases for Adaptive Systems (2011)
Gerth, Christian
Adaptivity is prevalent in today’s software. Mobile devices self-adapt to available network connections, washing machines adapt to the amount of laundry, etc. Current approaches for engineering such systems facilitate the specification of adaptivity in the analysis and the technical design. However, the modeling of platform independent models for adaptivity in the logical design phase remains rather neglected causing a gap between the analysis and the technical design phase. To overcome this situation, we propose an approach called Adapt Cases. Adapt Cases allow the explicit modeling of adaptivity with domain-specific means, enabling adaptivity to gather attention early in the software engineering process. Since our approach is based on the concept of use cases it is easy adoptable in new and even running projects that use the UML as a specification language, and additionally, can be easily incorporated into model-based development environments.
