Retailers are increasingly facing pressure to optimize their operations for monetary as well as environmental reasons, which is a highly complex challenge. A company called RELEX Solutions provides optimization software that helps retailers to sell more and waste less. This study investigates potential cognitive challenges in the usage of their application for supply chain optimization and designs a prototype of a feature to help daily users complete their work with less effort. This iterative study utilized pre-study knowledge, literature review, and initial interviews with internal users as a foundation to instruct the main user research and case selection. The main user research was conducted as a qualitative multiple-case study, including a total of nine customer users, from four different customer teams and three different countries. The qualitative data was gathered through one-hour semi-structured interviews and observations. These observations were performed either for a few hours before the face-to-face interview or using screen sharing to support the online interview. The research indicated that much of the users’ work could be defined as a set of processes, and the current folder structure feature provided suboptimal support for users’ and teams’ needs in completing these processes. As a result, this thesis has identified twelve cognitive load challenges and designed an interactive prototype of a process list feature with ten proposed solutions to meet these challenges. The study findings corroborate the literature on cognitive load theory and task management. Interestingly, however, the collaborative actions did not seem to be as disruptive as presumed based on the literature. In addition to the useful knowledge gained, the designed prototype can be utilized and easily adapted for further research. Furthermore, the prototype has received positive and promising initial feedback from both internal as well as customer users.
