Abstract

The existence of countless computerized personal decision aids has triggered the interest to investigate which decision strategy and technique are ideal for a personal decision aid and how helpful is decision aid to non-expert users? Two categories of decision strategies have been reviewed; compensatory and non-compensatory, which results in fusing the two strategies in order to get the best of both worlds. Findings from the study of focus groups show that multi criteria decision method (MCDM) known as Pugh matrix and lexicographic have been identified as two most preferred techniques in solving personal decision problems. Both, the strategies and techniques, are incorporated in the development of a personal decision aid design model (PDADM). The proposed model is then validated through prototyping method in two different case studies (choosing development methodology in mobile computing course; and purchasing a mobile phone). In measuring the helpfulness of the prototypes, this study is looking at four dimensions; reliability, decision making effort, confidence, and decision process awareness. The findings show that the respondents from different decision situations perceived PDADM driven prototypes as helpful.
