The research showed that all volunteers who used the online leave system between November 2022 and September 2024 were satisfied. It was found that the overall effectiveness of the system was considered to be at a high level (X̅ = 4.46, S.D. = 0.64). Satisfaction with the system's ability to perform its tasks is also at a high level. In terms of easy to use, efficiency is at similarly high level (X̅ = 4.43, S.D. = 0.62). In the case of data security, performance is at the highest level (X̅ = 4.54, S.D. = 0.59). From the results of the research conducted on a sample group of volunteers and based on the assessment of the applicable evaluation, the online leave system research on the case study of Phayao University Staff Branch has a high level of application.
