Introduction to Design Thinking by Alex Ryan

Design thinking is an approach to solving problems based on design principles. Design thinking is unique because it starts at desirability – it is human-centered from the beginning of the process, and only after understanding the user (ie. a person) in a deeper way does it narrow down options to what is feasible/ viable for the business/ service provider. It is not a linear process.

IDEO’s model found in their [Design Kit](https://www.ideo.com/post/design-kit) shows us how the solutions that emerge at the end of human-centered design should hit the overlap of these three lenses: they need to be desirable, feasible, and viable.

In the context of social innovation, solutions also need to be positively impactful for people.&#x20;
