Abstract: The software usability is considered as pooled form of understandability, learnability, operability and attractiveness about software. Usability is gradually more accepted as a significant quality issue for interactive software. This research is based on a case study of an educational industry that takes certain aspects that may be affecting the usability of software. The paper explores a SUMI questionnaire for stressing the importance and role of these factors. Also, a metric known as Cronbach's alpha is used to judge the consistency of software within use of the user. Finally, a regression-based model known as perceived software usability is proposed for enhancing the usability of software based on considered factors.
Keywords: SUMI; Cronbach's alpha; multiple regression analysis; usability metric; usability aspects; perceived software usability; PSU.
