Usability Evaluation of SMS-Based System: Basis for Systems Development

Abstract

The objective of the study is to evaluate the usability of SMS-Based Auto-Reply Inquiry System for Grades and Accounts. This descriptive study used a three-part questionnaire which was administered by the researcher. The usability questionnaire adapted from the USE Questionnaire used a 5-point scale composed of 30 statements. Convenience sampling was used choosing the respondents from the total population of 149 students of the CICS during the second semester of school year 2018-2019. A total of 45 questionnaires were retrieved and were used in the usability analysis. The usability evaluation results yielded a grand mean of 4.54 (Strongly Agree) showing that the SMS-based inquiry system is easy to learn, easy to use, useful, and satisfying. The results of this study show that pre-coded keywords are confusing for beginners but can be learned and familiarized by the users as they continue use the system. Further investigation should be conducted to prove that ease of use, ease of learning, and usefulness have direct impacts to user satisfaction.

“…In other words, the influence of technical support and course design on promoting continuance intention of using e-training can be strengthen if the e-training program perceived as useful by the participants [26][28].This result showed that perceived usefulness has important influence in both models i.e. direct or indirect effect model and supported by many previous studies on online learning [19][20][21][22][23][24][25] that perceived usefulness of e-learning product has significant role in influencing the willingness of users to continue using the product. Besides having a good technical support and well designed, the online platform for learning as well as training must perceived as useful by the participants in motivating them to continue using it or other platforms like it.…”

“…Learners have always been identified as having a useful and enjoyable experience if the online platform is user-friendly [23]. In addition, the perceived usefulness has been identified as a significant factor in predicting the continuance intention of using an online learning platform, either amongst school or university learners or employees of the organization [3][16][21][24] [25]. The results of previous studies have contributed to the understanding of the aspects that motivate learners to continue use e-learning.…”

“…This study was adapted from the Technology Acceptance Model (TAM) and the Mediation Model in the development of the conceptual framework. TAM is a well-known model that has been used by many previous researchers to investigate the impact of technology on user behaviour [5] [25] and theorizes that perceived usefulness determines user behaviour, but at the same time that variable is influenced by external factors. Thus, in this study, the external factors are represented by e-NPQEL features i.e.…”
