If the owner of the project (who designed the document) has very clear concepts of how the final designs will appear, it’s best to include any relevant sources or references to the brief to ensure maximum clarity.
When our designer will present the designer with 3-5 ideas resulting from their brainstorming and ideas stage, they decide the one you’d like to pursue. This will result in a seamless workflow for graphic design that will give you the best outcomes, quickly.
