William Penaflor Rey · 2023
This study aimed to assess the usability attributes of the MABIS mobile app among Philippine National Police (PNP) personnel, focusing on effectiveness, efficiency, learnability, memorability, errors, and cognitive load. A survey-based methodology was employed, following the dimensions of the PACMAD usability model. The findings revealed that the application exhibited consistently high efficiency, with task completion time, page duration, and interaction requirements meeting or exceeding expectations. The evaluated effectiveness categories performed at a highly acceptable level, indicating that the application effectively achieved its intended goals. Learnability was high, with users perceiving the application as easy to learn and quickly acquiring the necessary skills. The application demonstrated a relatively high level of memorability, enabling users to reuse it without assistance. Additionally, it excelled in error handling and recovery, providing practical aid and informative error messages. The application imposed a manageable cognitive load on users, allowing them to complete tasks within allocated time frames. Overall, the study concluded that the current usability of the MABIS mobile app was acceptable, acknowledging the subjective nature of usability influenced by user-specific factors. The research contributes to the literature on evaluating the usability of mobile applications in government institutions in the Philippines, offering insights to developers and designers. Future studies can expand the sample to include other government agencies and explore new evaluation methodologies for usability assessment.
