Here is a brief (<3′) introduction to innovation games, including a short talk by the one who “wrote the book” on them, Luke Hohman. One major use of such games is to inform prioritization decisions, that is, decisions about the relative value of product features or increments, from various perspectives. The three games mentioned here – “20/20 Vision”, “Prune the Product Tree”, and “Buy a Feature” – inform prioritization from the customer, strategic, and tactical perspectives, respectively.
