A copywriter can reshape a job proposal just as much as an account director can spot a campaign idea. Designers can write. Account execs can help shape commercial strategy. People contain multitudes beyond job specs.

We’ve mistaken these extra skills for collaboration or value-add extras – small, sometimes imperceptible things that make agencies unique – when it’s actually the stepping stone to something much more valuable: interoperability.

Open your creative APIs

To explain what I mean, I’ll borrow now from our tech clients and their thoughts on tech stacks.

Simply put, the best platforms don’t try to do everything themselves. They expose APIs, allowing specialist systems to communicate, exchange information and strengthen one another without losing what makes them great. It’s modular, effective and how many billion-dollar businesses operate.

I think agencies should work the same way.

We’ll still assemble teams by discipline, but we should allow for ways of working to develop naturally around the combined interests, capabilities and perspectives of the people in them. Designers with a knack for project management often make brilliant producers. Copywriters who naturally rationalize ideas are invaluable in client conversations. Strategists who sketch accelerate creative thinking.

Now, this isn’t saying that everyone can do everything. I’m not arguing against specialists. But too often, specialism begets isolation. And solitary gurus atop snowy peaks make for shoddy colleagues. Every discipline should expose its expertise to the rest of the agency while contributing to commercial success. That’s how people color outside the lines, grow beyond their job descriptions and create value that clients want to buy into.

Bet on guardrails

Of course, coloring outside the lines only works when people understand where the page ends.

Too often, agencies respond to new ways of working by adding more process. More approvals. More governance. More opportunities for good ideas to lose themselves in a sea of committees.

A ‘Creative OS’ does the opposite. It replaces restrictive processes with constructive guardrails: shared principles that explain how ideas move through the agency, where people can contribute outside their department, when human judgment takes over and whose expertise matters at each stage.

That’s the difference. Process is restrictive to a multidisciplinary professional. Guardrails are instructive. They demonstrate trust, bring art and science closer together and give people the confidence to build ideas long before they’re officially responsible for delivering them.

Everyone deals in both art and science

One of the biggest myths in agencies is that creativity belongs to creatives, commercial thinking to client services, and operations are the only ones organized enough to keep track of it all.

Think of soft skills, hobbies and side hustles. They’re untapped potential. For a business such as marketing not to take advantage of the things their people like doing in this climate, where every business and industry is converging, is deeply unimaginative.

Our current ‘stay-in-your-lane’ thinking works on a factory floor. In the business of selling ideas, not so much. As some job roles expand beyond scopes while others fold into themselves, rigid departments, roles and responsibilities ignore both business potential and human characteristics.

Everyone is a blend of both art and science; they simply express the balance differently. Recognizing that changes how we build teams and how we value contributions.

Letting careers grow

So what does that look like, exactly?

Firstly, define expertise. Job titles should signal expertise without limiting contributions. Specialists refine ideas. They shouldn’t be the only people allowed to have them. Secondly, let careers grow wild. Pots are for plants. But if a designer wants to be more client-facing or an account manager wants to learn strategy, encourage it. Growth rarely follows an org chart.

Thirdly, make room for surprises. Not every experiment succeeds, but every innovative agency makes space for them. The best ideas often come from the people you weren’t expecting. Fourthly, build safer playgrounds. Freedom only works with boundaries. Set clear expectations, respect specialist craft and establish guardrails that allow people to experiment without sacrificing quality

And, lastly, reward collectivism. All for one and one for all. Celebrate shared wins publicly, recognize individual contributions internally and build a culture where people compete with briefs, not each other.

This is how you run a ‘Creative OS’ that encourages agency-wide problem solving while protecting the specialist craft that makes great work great. It’s how your people can grow naturally and gradually while enjoying their job. It’s also how you can get the most value out of your people. Because creativity should be how an agency thinks instead of the prerogative of a single department.
