In this practice-oriented course, participants experience the steps through The Double Diamond innovation process to which they were introduced in course 5.1 Innovation Sandbox. They engage deeply in the human-centered innovation process, moving from contextual (user-based) research for (re-)defining a chosen problem, through creating concepts and prototypes for potential solutions. In subsequent courses (5.4 and 5.5) participants have a chance to bring their invention from this course to market and develop a business around it.
