When searching for quality feedback to be able to identify improvements, a designer needs to try a variety of questioning techniques.

It is important to consider the different types of feedback that can be gathered. If users are asked to provide feedback in the form of a questionnaire, the data gathered can be analysed more easily, eg the percentage of people who like certain colours or patterns. Asking a primary user specific questions on a particular aspect of design can help encourage honest and descriptive feedback. More general questions about favourite colours, styles and functional needs could show up ideas that haven’t yet been thought of.

Face-to-face or more conversational interviews give designers the chance to ask questions and help users form an opinion by offering options for new iterations. Offering examples, such as models or prototypes, that users can provide feedback on is helpful. Working collaboratively with other designers can provide honest, creative feedback, as well as possible solutions to problems that might prevent or hinder design development.

Iterative design

Iterative design is a circular design process that models, evaluates and improves designs based on the results of testing.

The iterative design process works by analysing the evaluative feedback received and using it to redevelop the product. Further improvements can be made and then more feedback can be gathered until both the client and the primary user are happy with the outcome.

Without the iterative cycle of evaluation and improvement from both the primary user and the primary user, the product may not be the best on the market. This will allow another manufacturer to produce a better product that will be more successful.
