Abstract:Making decisions in increasingly complex environments is a challenge for decision-makers due to cognitive information-processing limitations. The sales domain is exemplary for situations in which decisions need to be made under high time-pressure and high pressure to succeed. Many companies have implemented Decision Support Systems (DSS) in the field of sales (Roh, Ahn & Han, 2005). Many DSSs have failed so far due to poor design and usability (Horsky et al., 2012). It is therefore crucial for a successful implementation of DSS to have a usability validation framework. Research on usability validation frameworks in the sales domain is limited (Mysiak, Giupponi & Rosato, 2005; Schmettow, Schnittker & Schraagen, 2017). Schmettow, Schnittker and Schraagen (2017) successfully proposed an extended validation protocol for evaluating medical DSSs. The goal of the study was to assess a methodological transfer of the extended validation protocol into the sales domain. For this purpose, a case study has been carried out in which a novel concept has been compared to the legacy one. Qualitative analysis revealed, that with the novel design, still a number of usability problems remained. Nevertheless, quantitative comparison of the designs showed an overall improvement in efficiency of use and learnability for the novel design, which suggests that a methodological transfer of the framework by Schmettow, Schnittker and Schraagen (2017) into another domain is potentially possible.
