What is the primary purpose of a design brief?

The primary purpose of a design brief is to outline the project's goals and constraints. A well-structured design brief serves as a foundational document that defines what the design will aim to achieve, including specific objectives, target audience, timeline, budget, and other key parameters that define the scope of the project.

By detailing these aspects, the design brief provides clear guidance to designers and stakeholders, ensuring that everyone is aligned on the goals and that the project remains focused throughout its development. It effectively sets the stage for creative and strategic thinking, allowing designers to generate ideas that are informed by the project's specific needs and limitations.

In contrast, summarizing the final design outcomes focuses on the results rather than the initial intentions; providing technical specifications is more about the details necessary for implementation rather than the conceptual framework; and evaluating the success of the design comes after the design has been completed, making it a retrospective activity rather than a guiding document for the design process. Hence, the design brief plays a crucial role at the start of the design process, making option B the correct choice.
