As you can see from the above list, and from the chapter, there are numerous strategies for versioning. Some of them require significant product and development and research and development (R&D), and others require modest investments and change in a product or service. Some of them require repositioning of the product through marketing and promotion efforts. The FAD (features, attributes, and design) template, which is introduced in Chapter 7 "Conceptualizing Products/Services Using FAD", is very useful for identifying features and attributes that can be used to version products and services for Midas, Atlas, and Hermes customers.
