A design brief is a document containing a set of instructions which outline the desired results of a project.
There’s no set way of writing a design brief, but they will always share the same purpose… to set out a list of aims and objectives. This is so that you understand what you’re designing and why, and more importantly, so both you the designer and the client understand what the final outcome is intended to achieve.
Before you can create a design brief, you need to gain a good understanding of the business, its competition and its audience. You do this by asking questions.
