Enhancing User Experience through Optimization Design Method for Elderly Medication Reminder Mobile Applications: A QFD-Based Research Approach

Poor medication adherence among older adults is a widespread problem worldwide. As the population ages, design of smartphone management apps critical to improving adults. Taking an elderly reminder APP as example, this study proposes sustainable research method that integrates KANO model, Analytic Hierarchy Process (AHP), Quality Function Deployment (QFD), and PUGH decision matrix. The collects user demands through in-depth interviews, applies model classify these demands. hierarchical structure needs established by using AHP, priority sorted according weight importance determined judgment QFD used translate into requirements, house quality matrix identifies key requirements. Finally, alternatives are evaluated Pugh’s concept selection method. results demonstrate integration KANO-AHP-QFD-PUGH can be effective optimal approach for experience application elderly. This integrated not only facilitates innovative optimization sustainability methods but also provides valuable theoretical practical insights future drug-assisted users.
