Why Marketing Briefs Still Fail

Across my career, I’ve worked on both sides of the briefing process, writing briefs and responding to them. The same pattern appears again and again. 

A brief lands with good intention (many in a well-designed template). Yet the output misses the mark – it’s ‘not quite right. Revisions follow, timelines stretch, budgets increase, and frustration builds. 

It’s easy to blame execution. In reality, the issue starts much earlier. 

Templates aren’t the problem – unclear thinking is 

Most organisations now use briefing templates. They cover the essentials – objectives, audience, messages, deliverables, and on the surface, they look complete. 

What tends to go wrong is more fundamental: 

• Objectives are vague – ‘drive awareness’ or ‘increase engagement’ rarely provides real direction 

• Assumptions go unchallenged – the brief often reflects internal thinking that hasn’t been tested  

• Decision points lack clarity – It’s not obvious what success looks like 

• Context is incomplete or inconsistent  

The result is a brief that looks finished but lacks precision, leaving teams to interpret and fill in the gaps—often leading to misalignment. 

This isn’t a new issue, nor is it isolated.  

During our National Marketing Competency Framework Advisory Panels, ‘writing effective marketing briefs’ consistently emerged as a challenge across the board amongst our members.  

Where AI adds value   

AI offers a practical way to strengthen that thinking. It doesn’t replace the marketer – it acts as a partner to improve clarity, rigour, and decision-making. 

In fact, it was during an AI Masterclass in ChatGPT last year that this question first came to mind: how can we use AI, as marketers, to create better briefs? 

In practical terms, AI can help marketers; 

1. Define the problem more clearly
2. Improve decision clarity
3. Stress-test briefs before sharing
   

The impact? Are better briefs 

Stronger briefs lead to: 

• Less rework  

• More efficient use of budget  

• Higher quality outputs  

• Better working relationships  

Ultimately, better briefs drive better decisions – and better outcomes.

At MII, we’ve seen growing demand for practical guidance in this area. Our 2-hour AI masterclass on marketing brief writing is designed to help marketers: 

• Frame problems more effectively  

• Strengthen decision-making  

• Stress-test briefs before sharing  

It’s a practical, hands-on session focused on improving a critical marketing skill.
