Hi Isaac! I really like your post :) I love Design Thinking however I believe that it lacks of some important aspects and metrics to make things happen and you tackle it with the "start-up master class".
Related to what Kate say some comments below, i think it will be nice that this people formed could be formators, so they could teach what they have learn in their communities and challenge for example hight school kids to solve small problems in their classrooms or neightborhoods. This is a win win relationship, for learners because they learn more (some times i get things more clear when i tach to other) and for community because they get an approach to this techniques and maybe be more involve later and get encourage. I believe is important to have at least a 5 months course to get the Design Thinking culture and then continue applying for life.
Hi Isaac Thanks for checking my idea, I think your ideas are great i will look at them more close to comment. I consider challenges should be between 5-12 months I believe is the right time to learn and develop something
