Good Design Is Built Through Iteration Design with just its basic set of rules that guide needs to not be spoken in absolute. Every designer is a creator, and understanding the users of a product enables each designer tailor his product using his own design techniques, backing it up with decisions as to why each feature was established on the product. But one thing that remains important regardless of the designer’s approach is the willingness to iterate. The first version of a design is rarely the final version because design is a process of learning, testing, observing and refining. Iteration gives designers the opportunity to challenge their initial assumptions, identify friction points, respond to user feedback and continuously improve the experience.
