The purpose of this paper is to demonstrate the application of Decision-Based Design (DBD) framework to a commercial product—a Foldable Hand Truck. This paper’s new contributions to DBD framework are the application of discrete choice analysis (DCA) in DBD framework that greatly simplifies the task of customer survey, resembles the real purchase behavior of the customers and reflects their preferences on the product design better, and recommendations for the utilization of the DBD framework in future product design applications. The selected application problem is a Foldable Hand Truck. In contrast with the conventional hand truck, a foldable hand truck can be folded and moved through the stairs. Also, the feature foldability saves a considerable amount of storage space.
