Design Thinking...What is that?

Mark Dziersk from Fast Company describes design thinking as: the methodology commonly referred to as design thinking is a proven and repeatable problem-solving protocol that any business or profession can employ to achieve extraordinary results.

This is best explanation of Design Thinking I have read.

Dziersk breaks it down into four parts:

• Define the problem
• Create and consider many options
• Refine selected directions
• Repeat ( optional )
• Pick the winner, execute

"Defining the problem via design thinking requires the suspension of judgment in defining the problem statement. What we say can be very different to what we mean. The right words are important. It's not "design a chair", it's…"create a way to suspend a person". The goal of the definition stage is to target the right problem to solve, and then to frame the problem in a way that invites creative solutions."
