Product definition through the design-by-use process

To promote product quality, a design process should represent the needs of all who will use, develop, or modify the product. The service creation environment (SCE) for the A-I-Net™ adjuncts, a family of products that allow service providers to control the definition, development, and evolution of advanced intelligent network services, was developed with a design-by-use process. This process is an iterative cycle of analysis, prototype construction, and user evaluation. It uses human factors and system prototyping techniques to involve potential users of the product early in the product definition and design stages.
