It isn't the job of your customer to translate their needs into your product offerings. Of course, everyone says you just need to listen to your customer, but no one says how.  In "Innovation Games" Luke Hohmann describes 12 games you can play to help you better understand your customers' needs and help you discover great products.

In part I, Luke first provides an overview for understanding and implementing innovation games.  He then discusses the process from selecting the game to interpreting the results.  

In part 2, twelve separate games are described which can help you understand one or more of the following:
    - Unmet and/or idealized market needs
    - Products and services usage and relationships
    - Product and service functionality
    - How to shape your product for the future

Finally, in part 3 tools and templates are provided to help you quickly start playing innovation games with your customers.

In a world where the mantras of "innovate" and "listen to your customer" prevail, Luke Hohmann gives you usable tools to help you do just that.
