Usability Performance Evaluation of Information System with Concurrent Think-Aloud Method as User Acceptance Testing: A Literature Review

摘要

In order to evaluate the user interface of information system in websites, softwares, applications, etc, some methods are needed to capture fully what is perceived by the user when accessing an interface, whether websites, mobile gadgets, desktop computers, and so on. One method that is growing in evaluating the usability of the user interface is a Concurrent Think-Aloud method. This method is an assessment method by including the verbal or speech opinion of the respondents and the respondents assessment results recorded during the evaluation process in real time. Since this method is conducted by end-user, then the result will have beneficial added value for information system improvement as good as already known method, Black Box Testing as one of User Acceptance Testing (UAT). One of weaknesses that can be found in this method is that some respondents may not show any expression or say to the evaluated website. This can be due to the character of the respondents themselves who tend to be less expressive. The advantages of this method are the developers of the information system can immediately understand what is experienced by end users rather than just using a questionnaire whose data collection tends to be less real time and make users tend to forget their real experience, and think-aloud method also can maximize end user's contribution to the UAT process.
