Prototyping: Create an initial prototype using the most feasible and efficient methods available, whether it's a physical model, a digital simulation, or a minimum viable product (MVP).
Re-testing: After making modifications, retest the updated prototype to ensure that the changes have addressed identified issues and improved the overall performance.
Documentation: Keep detailed records of each iteration, noting changes made, feedback received, and the reasoning behind modifications. This documentation helps in tracking progress and decision-making.
Retesting: Following revisions, test the updated prototype once again to make sure that the fixes have resolved any problems and enhanced performance overall.
Lots pf hypotheses. Then working through them. But always by recognising stakeholder biases. The biggest impediment to prototyping is various biases and letting go of the ego. Are you creating something for you or your market?
