During this phase you will be required to create basic and cost-effective mock-ups of your idea to test with real users. Here you will challenge your assumptions and gain further understanding about the context and key features of your product/service. It is important not to be too attached to your first prototype, as the quicker you fail and move on to an iterated design – the better the end result will be. Ultimately, we are looking to validate whether the problem we have identified, ideated on and tried to solve is actually the right problem.
