A Systematic Design towards Usability for Novice Designers
Abstract: Dependence on
intuitive and experiences would add more complexity in the design process. Novice
designers would follow the design of any existing systems without direction.
This paper proposed a systematic design approach that provides guidance for
novice designers in achieving the targeted usability goal using patterns, and
evaluating the prototypes in achieving the determined usability goals. The proposed
approach involved the cooperation of experts in providing direction to the
novice designers in achieving usability goal in the system design. A collective
decision both from users and experts would be gather to give a clear decision
of a chosen prototype. Two experiments that followed the proposed approach were
conducted with 7 groups or 33 undergraduate students. Ten industry experts, 10
field experts and 29 prospective users were involved in evaluating the
appropriate use of the tool to assist them in making decision during comparative
prototype evaluation. The result from both experiments concluded the systematic
approach could help the novice designers to emphasize usability along the
design process. It was observed that the achievement of important goals in
their designed prototype could be easily done if pattern selection was provided
to the novice designers. The designed tool to assist novice designers has high
reliability and high acceptance level of appropriate of use in making decision
for the preferred prototype.
