This document provides guidelines for writing an effective client brief for communications agencies. It emphasizes that a written brief is crucial for setting clear objectives and expectations upfront. The brief should clarify the current situation, the desired destination or goals, and how success will be measured, but not dictate how agencies do their work. This ensures agencies can be creative while understanding the goals. A written brief followed by discussion allows all parties to be on the same page and align their efforts. Proper briefing saves time and money by avoiding wasted work from unclear or changing directions. It also enables fair payment based on results. The guidelines recommend brevity, focus, and concrete, measurable objectives in the brief.
