Suunnitteluohjeen kehittäminen kognitiivisen ergonomian huomioimiseen käytettävyyden parantamisessa
Abstract
Today, it is almost impossible to avoid interaction with IT-related tools. Therefore, when designing systems, it is important to consider people’s cognitive abilities and limitations to avoid production errors and excessive burden on people. In cognitive ergonomics, the interaction between humans and technology is studied and designed especially from the viewpoint of human cognitive processes. Cognitive ergonomics aims to shorten task times, reduce mistakes made by people, shorten learning times, and improve people’s satisfaction with the systems. Cognitive ergonomics can be considered as an important scientific basis for user interface design. In this study, the aim is to find out how the system’s usability can be affected by improving cognitive ergonomics. The study was conducted using the design science research approach in the context of the technology industry. The human-centered design viewpoint of technology is increasingly important in the industry context as the number of IT-related tools grows. In the study, the usability of the target company’s SAP ME system was improved with a focus on the aspects of cognitive ergonomics. As a manifestation of the research’s aim, an IT artifact, i.e., design instructions for improving usability from the viewpoint of cognitive ergonomics, was created.
