Many innovative products and services are actually complements of the original products. The innovation can be an add-on feature, an after-market service, or a different product or service. Transportation devices have spurred the development of substitute energy sources such as steam, electric, fuel cells, and solar energy. The automobile was the driving force behind the development of better roads, fueling stations, diners, and truck stops. The development of better sailing ships led to the need for complementary devices for navigation tools such as maps, star maps, compasses, sextants, and GPSs. The FAD template and the Strategy Canvas can also be used to identify competitive complementary products and services.
