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.

Abstract

We present a possible method and tool to supportthe novice designers in the design tasks. Although in literaturestated that practitioners depend on memory and experiences,novice designers would take time to learn to acquire sufficient experience. The purpose of this research is to help novicedesigners to fulfill the usability goals that have determined by theexpert in designing a system. The proposed methodology and toolcan be considered as an assistance tool for novice designer indecision making in regards to prototype selection as well as thetask-pattern mapping template for pattern selection in fulfillingthe usability goal targeted. The tool was designed to manage thedecisions information and to recommend the chosen prototypebased on the Analytical Hierarchical Process (AHP) technique. Inoverall, about 87% of expert evaluators and prospective userswere agreed with the suggestion of prototype selection from theproposed tool. The findings from this study revealed that thecooperation from industry experts was valuable in determinedthe usability goal and direction and getting accumulativefeedbacks both from users and experts.
