In the testing stage, the prototyped ideas are tested with a broader user audience. Feedback from users during this stage informs any final adjustments and ensures that the end product aligns with user needs and expectations. This is when we start turning the design into something real and see how it works in real life.

Even though we talk about these stages one by one, remember that design thinking is a non-linear process. The iterative approach allows designers to go back and change things based on new feedback or ideas. This flexibility ensures continuous improvement and innovation throughout the design journey.
