As a design student, we are often given with the task (What) and according to that we will start our design process (How). We learn and apply our methodologies and jump to our conclusion, the Design. Finally, we will be graded and being criticized by our tutors, and in most cases, it is the question of why that governs the judging criteria. So, our learning path can be seen as:
(What) > How > (Why)
Noted that what and why is in brackets, because they are initiated by the school. The only question that we have to resolve is How. Knowing that design is about problem solving, and the prerequisite to that is to identify the problem. Without truly comprehension of the problem, our methodologies can be off and there comes the catastrophe, so called Bad Design.
The best point about 10Touchpoints is that it asks designers to seek the reasons to design. Learning to identify and analyze the problem is essential and it triggers thoughts, generates constructive ideas and produces Good Design. Learning path becomes:
What > Why > How
Via the process of identification and analyzation, we can decide (design) our solution(s). Only by 'doing it' (going through the entire process), in my own opinion, is How design education is supposed to be.
