Important points about low-fidelity tests leveraged in Design Thinking via Forbes.
“Low fidelity tests are the darling of design thinking, and you have to constantly try out and toss new ideas that don’t work for customers. It takes discipline to say, “Okay, engineers. We’re not going to start building this yet because we’ve got to draw pictures first and show it to more people.” Getting this right is more important than just pushing out a product. Invest time early on in the iterative process so that once you are ready to develop a product, it is full speed ahead.”
