A systematic approach for coupling user satisfaction with product design

A fundamental assumption in this paper is that user satisfaction depends on product design. The approach consists of 5 steps: ( 1) de. ne user satisfaction, ( 2) decompose product design elements, ( 3) conduct experiments, ( 4) develop relationship models, and ( 5) analyse critical design features. In order to demonstrate the practicability of this approach, relationship models were developed based on experimental data using a total of 60 subjects ( 30 American and 30 Korean subjects). In addition, critical design features and their common properties were identified for audio/visual consumer products. Similarities and differences between American and Korean consumers were discussed. The resulting relationship models can be used to predict user satisfaction and provide significant remedies for design change.
