Evaluation of a Child Immunization Schedule Application using the Software Usability Measurement Inventory (SUMI) Model

Abstract

Immunization has become part of the obligation for the parents to protect their children from major childhood diseases. The Malaysian government has emphasized on immunization programs on children to reduce mortality rates among children. Therefore, we developed a mobile application known as Baby Vaccination Schedule (BVS) with vaccine schedule reminder to decrease the rate of incomplete immunization due to overlooking of the vaccination date. In addition, this application aims to provide parents with knowledge on vaccine uptake for the children. One of the crucial parts in development of any software or system is to what extent the proposed solution may satisfy the user requirement. In this paper, Software Usability Measurement Inventory (SUMI) is used to evaluate the BVS application. The BVS application had successfully complied with all five factors in SUMI model which are, efficiency, affect, helpfulness, controllability, and learnability. The total mean represents the value which are related to the standard of the mean value in usability testing. The higher the mean value from the higher the data respondent from the respondent. The result classified that the level of usability in Baby Vaccine Schedule at 89% acceptable by the user. Thus, the respondent agreed that the apps can be used to solve the problem in spreading information and notify user on vaccine schedule.
