The Application of Quality Function Deployment to User Interface Design

Abstract

This article focuses on the use of quality function deployment (QFD) to define the unspoken customer requirements in user interface design. The relationships between customer requirements such as learnability, speed of use, and so on, and the realization mechanisms or performance measures such as consistency, error management, and others, are shown in the house of quality. The use of QFD has resulted in a better focus on the key issues in user interface design and translating these into actions and designs, reducing user interface design errors and increasing customer satisfaction.
