Write a good design brief
When you are hiring a graphic designer to do a project you need to provide him with a creative breif. Let the graphic artist know about your business and be concise.
What is the goal of the new project?
What are you trying to communicate?
Are you trying to rebrand or just update promotional material.
If so provide the designer with the old material.
Who is the target market?
What are their demographics?
If there are many, rank in order of importance.
What information needs to be in the piece?
Who is providing the copy?
What pictures/ photos/ diagrams need to be used?
Who is providing them?
Where is the design going to be printed/ used? (Web, business cards, stationary)
Provide a budget so the graphic artist can maximize the project.
Set a realistic deadline.
Consider time for consultation
With these questions answered expectations are set and the process will run smoother.
