A crash course in changing the world.
Provide skills, not just finished technologies. The current revolution in design for developing countries is the notion of co-creation, of teaching the skills necessary to create the solution,
rather than simply providing the solution. By involving the community throughout the design process, you can help equip people to innovate and contribute to the evolution of the product. Furthermore, they acquire the skills needed to create solutions to a much wider variety of problems. They are empowered.
I think this is a great secret! It teaches that we can't survive in the modern world without certain skills. It is all very well to have so much technology that you don't need to know the skills but what if a machine breaks? Communities need to know how to fix what was given. But if we teach skills as well then the contribution is valued much higher.
