During Phase , each individual will submit their own idea for an innovation along with a model they find useful for evaluating its merits. Each team member is responsible for completing research on various models.
While there are several models in circulation for evaluating innovations, such as The Lean StartUp Plan, NOMMAR, SNIFF, and the linear and mental models of innovation, innovators should not feel constrained by any particular model.
Feel free to borrow elements from multiple models to develop one that would work best to most effectively evaluate your own innovation.
