Agencies often pitch exciting, ambitious "North Star" campaigns that get one department excited. However, these ideas frequently fail because the client's internal teams (e.g., digital, PR, comms) are siloed and not aligned. The agency sells a vision that other departments ultimately block, leading to an inability to deliver.

Most brands never unified their marketing operations. Instead, they bolted on new models for digital, social, and influencers, leading to siloed teams, inconsistent briefs, and conflicting agencies. This hidden complexity is why creative work suffers.

A key, unspoken role of a marketing agency is to provide political cover for the in-house leader. The agency can act as the "voice of reason," holding the line on unpopular but necessary strategic changes and using their broad industry experience as justification, thus absorbing the internal friction.

Ad agencies possess immense creative problem-solving talent but narrowly confine it to communication campaigns. They could deliver enormous value by redesigning a menu's choice architecture or fixing customer journey friction, but don't because clients lack the job titles and procurement processes to buy such "trivia."

Structuring marketing teams in channel-specific silos forces them to optimize for internal structures rather than the fluid, non-linear path customers actually take. This creates a fragmented view of performance, leading to wasted effort and missed opportunities.

The number one mistake in annual planning is creating a marketing strategy in a vacuum. A plan disconnected from company-wide goals, such as a major product launch, results in resource misalignment, budget shortfalls, and missed growth opportunities.

Companies often over-invest in safe, committee-approved ideas that yield minimal results. The real financial danger lies in the missed opportunity of bolder, seemingly riskier campaigns that are more likely to capture consumer attention and drive growth.

Agencies are optimized for efficiency, stifling the creative experimentation needed for platforms like Meta. Top-performing brands employ an in-house strategist whose sole job is generating a high volume of diverse, "wacky" ad concepts—a function that can't be effectively outsourced.

Novartis's CMO observed that marketers have become too distant from the creative work by outsourcing it. Bringing some work in-house eliminates translation layers, increases agility, and helps marketers regain an intuitive feel for the craft.
