This chapter looks at different approaches to design. Mainly to understand how design thinking is taken forward, who are the people involved, what are the different theories, and how to work with users to make an invention a success in the market.
 
My take on the IB Curriculum Structure:
If you see the IB curriculum, you will find that the way I have put together the chapters, they differ in order. This is because this is the best way (I feel) to teach Design Technology. Starting from how one comes by ideas, develops them, manufactures them, keeping comfort a priority, and manages resources to come up with a great design solution.
