The design iteration process is the way in which designers iterate towards a more refined Design or outcome. This is done through evaluation of tasks a repetition of the design process.
Traditionally in problem solving design the waterfall method of design would be used to approach and solve the design problem. This is where you start with a problem then carry out the following steps requirements, ideas, prototype, acceptance and release. This is the way from a client point of view would like the development of a product to happen and would be most effective. However, from a designer’s point of view this doesn’t allow room for greater development and experimentation on there behalf.
Designers prefer the iterative method of design problem solving. This is where the process of ideas, experimentation, prototyping and evaluating is carried out several times and would be evaluated by the client or the designer themselves after each iteration. This process allows the response to the problem to be more the clients requirements and refined to create a much more satisfying outcome for both.
-The client would have an idea of a product (toothbrush) they want to produce that the designer would take on for further development.
-From this he would come up with more ideas and development of the product (improve the ergonomic or style).
-Next he would produce a mock or prototype to test to see it works and asks for the client opinion (to give the client an idea of the final product).
-This process would be repeated until the client is satisfied with the final outcome.
-Only then would the produce be released to the market to be mass-produced.
