In the past decade, home appliances have been rapidly developed to satisfy the various requirements of users. Thus, there are increases in requirements to explore appropriate evaluation methods that reflect the usability of home appliances quickly and comprehensively. This study aims to develop a scenario-based usability checklist for product designers early in the design process. In this study, the scenario-based usability checklist consists of two parts: 1) a heuristic evaluation checklist, and 2) a scenario evaluation checklist. In heuristic evaluation checklist development, usability factors of home appliances are extracted and then coupled to user interface (UI) elements. In scenario evaluation checklist development, scenarios are developed through brainstorming by focus group interview (FGI), and then evaluation elements are extracted from previous scenarios analysis. The proposed scenario-based usability checklists can enable designers to evaluate product design quickly and comprehensively early in the development process with users' viewpoints.
