Which of the following is NOT a purpose of the design brief?

The design brief serves as a foundational document in the engineering design process, outlining essential elements that guide the development of a project. While it is instrumental in identifying a problem to be solved, encouraging brainstorming, and defining criteria and constraints, it does not involve the testing of prototypes.

The primary purposes of the design brief include setting the stage for the design challenge by clearly stating the problem and its context, facilitating creative thinking through brainstorming, and establishing specific criteria and constraints that a solution must meet. These components are crucial for a structured approach to problem-solving in design.

Testing prototypes is a later stage in the engineering design process, typically following the initial brainstorming and design phases. It involves evaluating how well a proposed solution meets the established criteria and addresses the defined problem, often requiring additional documentation and results beyond what is covered in the design brief itself.
