An Investigation of a Personas-Based Model Assessment for Experiencing User-Centred Design
User-centred design (UCD) has been widely used to solve those failure products that are not proper designed for target users. Although UCD techniques are varies, some similar drawbacks were found as it requires complex skills to manipulate and it is time consuming as well as costly. Big enterprises have no problem with carrying out UCD because of rich resources. However, most of researchers made effort on the improvement of approaching UCD. Lack of studies contributed to the area of promotion UCD to those companies which do not launch UCD correctly or barely know UCD. Neither any of studies addressed on the investigation in difficulties those companies have and therefore helped them to be solved. Hence, this research aimed to assess a cost-effective UCD model to assist designers in idea generation. 16 designers were invited into the two-phase assessment. In addition, there were 51 end users as the participants to evaluate that if the designers who followed the proposed model can generate better UCD ideas. In this project, an MP3 was chosen because it is portable, easy, and with both aesthetics and functionality factors. In addition, 25-34 office workers were selected as the target users as the participants. This research was a whole process of the assessment of a cost-effective UCD model in assist designers’ idea generation, and this assessment successfully showed that the cost-effective UCD model could eliminate the complex of the UCD skills and the cost, in which the UCD results were identified by the users. Therefore it could encourage more designers to apply UCD in their work. Further recommendations were also illustrated in this paper.
