Usability evaluation to approve an information system design (case study: Immunization monitoring interface design)

Prototyping is a useful technique to support the development process of building a software application. It is beneficial particularly when the developer focuses on the user. However, in the requirements phase, the developer has problems to give visualization about the task that should be done when the user interacts with the information system. So, this paper aims to demonstrate that with the usability evaluation in the requirements phase, it can help the IS developer to achieve approval from the potential user of the IS. This paper employs a case study in the process of developing Immunization Monitoring Information System (IMIS) at the Srondol Community Health Centre (Pusat kesehatan Masyarakat / PUSKESMAS), Semarang, Indonesia. For the experiment, this paper only uses two potential IMIS users. The IMIS interface will be tested for its usefulness with variable effectiveness, efficiency, and easy use. The output generated from the experiment was an effective, efficient and easy-to-use interface design for IMIS from the perceptions of child guardians and the perspective of Community Health Centre staff. This paper provides recommendations, that in the requirement process, usability tests can be used to get approval and recommendations from potential user of information systems.
