POINT OF SALE OF CTU- DANAO CAMPUS CANTEEN: USABILITY STUDY

The study examined the usability of the Point of Sale (POS) system implemented in the Cebu Technological University-Danao Campus Canteen that addressed long queues, particularly during peak hours, and improved service quality. The system’s performance was evaluated based on six key factors of effective usability: ease of use, task completion, user comfort, satisfaction, system capabilities, and error feedback. Data collection was done using a time and motion study to gather data on the average service time in minutes for customers' orders per day and a seven-point Likert Scale survey to test the usability of the POS System. The survey respondents included five instructors (17%). Ten canteen staff (33%), and fifteen students (50%) of the total sample were selected through a random sampling method. The analysis revealed significant improvements with consistency in average service time; with the utilization of the POS system, a 37.72% efficiency improvement rate was achieved. Average service time decreased to 0.58 minutes per transaction, compared to the previous system's 1.25 minutes. The strongest performance was observed on Day ten, with an average transaction time of 1.10 minutes. The usability rate is 4.1 based on ease of use and 4.7 regarding error feedback. Results from the Likert scale showed a wide range of scores between 5.30 and 6.15, demonstrating very high user satisfaction and efficiency. The findings revealed significant improvements in the POS system in terms of boosting service efficiency.
