The previous chapters have focused on learning the basic concepts related to product differentiation in the context of monopolistic competition. The focus of this chapter is learning-by-doing. We will use techniques to help transform a nagging idea about a new product to be more explicit and real. The tool for completing this task is called the FAD (features, attributes, and design) template. The FAD template is used to identify the features and attributes that can be used for product and service differentiation. The first part of the chapter will introduce the key concepts necessary to understand and motivate the use of the FAD template. The FAD template will then be introduced and used to demonstrate and structure the development of important attributes and features of a new product or service.
