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.

PepsiCo intentionally hired a leader with a marketing and consulting background to head consumer insights. They rejected the 'promote the best surgeon' model, believing an outside perspective was essential to galvanize the team and connect its work directly to business needs.

A CMO's primary job is not just external promotion but also internal marketing. This involves consistently communicating marketing's vision, progress, and wins to other departments to secure buy-in, resources, and cross-functional collaboration.

Amazon's CCO explains that at an agency, creativity is the core product. In-house, it's just one business function among many. This requires a humbling shift from "selling" ideas to deeply understanding the business constraints and priorities that drive decisions, moving from being listened to, to being the listener.

A CMO's key function isn't just advertising but acting as the internal voice of the customer. This requires creating planned "mutiny" with data to shake the organization out of stagnation and force it to adapt to market realities before it becomes irrelevant.

Look for a marketing partner who will educate you and your team, not just execute tasks in a black box. The most valuable agencies explain the 'why' behind their strategies, leveling up your entire organization's marketing knowledge and fostering a more collaborative, effective relationship.

GM's marketing leader reversed a trend of outsourcing key functions. He argued that relying too heavily on agencies underdeveloped internal skills, making the company slow and unaccountable. Bringing capabilities in-house, while challenging, was essential for transformation and agility.

A CMO's influence is often wielded covertly. By framing marketing goals in the language of other departments and allowing executives to believe ideas are their own, CMOs can navigate politics and implement their agenda successfully.

Marketers can feel frustrated by the constant need to educate the company on their work. However, effective leaders reframe this perspective, understanding that internal communication and building trust are not distractions from the 'real work'. Instead, they are a core, essential part of the leadership role itself.
