Abstract

This study aims to suggest a systematic evaluation framework to evaluate design concepts of a new product at the conceptual design phase based on users' requirements and tasks, development trends of relevant technologies, and the CPV. The proposed framework to evaluate design concepts of a new product consists of three phases. In phase 1, we identify and analyze users' needs, functional requirements and their expected tasks by utilizing user scenario-based analysis and hierarchical task analysis. In phase 2, by deploying a relevant technology roadmap, we investigate technology alternatives for satisfying the user needs or functional requirements. In phase 3, we evaluate the design concepts using evaluation checklist, which is based on functional requirements derived from relationships analysis, utilizing CPV attribute for a quantifiable measure. A case study was demonstrated to evaluate the design concepts of a new CSCW-based tangible interface that was recently designed to support group decision making activities.
