Rattaphum College, Rajamangala University of Technology Srivijaya, previously managed its durable articles through a document-based system, leading to frequent issues such as data loss, redundancy, and difficulty in searching and editing information. This research aimed to (1) develop a durable articles management application using QR Code technology, (2) analyze operational efficiency after applying lean principles, and (3) assess user satisfaction with the new system. The research was conducted using lean principles to reduce steps and time in the operation. The efficiency was calculated from the ratio of total working time to the sum of valuable time. The developed application includes features for QR Code scanning, searching, adding, and editing durable articles, as well as user management. Results showed that, for staff, the application reduced work processes by one step, saved 12.84 minutes, and increased efficiency by 56%. For general users, work steps were reduced by three, with the same time savings and a 72.22% increase in efficiency. User satisfaction was also evaluated, with application design receiving a very good rating ( = 4.50, S.D. = 0.70), and overall system usability rated as good (
= 4.46, S.D. = 0.69). The study also revealed that an easy-to-use user interface design and the perceived usefulness of the system are important factors influencing its acceptance. This system demonstrates significant improvements in efficiency and usability and can serve as a model for implementation in other educational institutions with similar needs.
