Opinion · Operating model · The CMO of the decisioning eraFrom campaigns to decisioning
For thirty years, marketing was built around the campaign.
In the agent era, it is built around the decision.
A CMO planning meeting. The deck on the table proposes next year's campaign calendar, the same shape the team has reviewed every January for fifteen years. The brand colours are updated. The channel mix has shifted. The agency partners are mostly the same. One slide is different. It proposes that the lead for the next campaign cycle is not a person but an agent. Someone in the room asks the question the org chart cannot answer. Who is the agent's manager? A version of that scene is happening inside CMO offices on every continent. The agent has arrived inside the marketing organisation. The campaign calendar still exists. The org chart does too. Neither has yet been redrawn around what is actually changing: the unit of work.
The operating model the campaign era built
For thirty years, marketing has been built around the campaign. Around the campaign, marketing built a recognisable operating model. Campaign managers ran the project. Segment builders assembled the audience. Creative agencies produced the creative. Channel leads tuned the buy. MarTech ops kept the stack running. Analytics teams measured what happened. Each function exists because the unit of work is the campaign.
The campaign has a brief, a budget, a calendar, a creative review, a measurement window and a post-mortem. The artefacts are industrialised. Marketing's headcount, its skill mix, its KPIs and the way it spends its quarter all reflect this. Even where MarTech has changed beyond recognition (Scott Brinker's chiefmartec landscape counts more than fifteen thousand tools, and the average enterprise now runs roughly ninety), the operating model has stayed essentially the same.
What changes when the unit of work changes
The agent era moves the unit of work from the campaign to the decision. Every customer interaction becomes a unit of measurement, not just every campaign. Three things shift.
Campaign managers manage fewer campaigns that fewer humans now run. The agent runs the campaign at the unit level. The campaign manager moves up to setting the brief for the agent, or moves out.
Segment builders are obsoleted by agents that compose context dynamically. The agent does the work of traversing distributed sources. The segment-building function was built for a world where humans assembled the audience by hand.
Analytics teams that measured campaign-level outcomes have to measure decision-level outcomes. A million decisions a day produces a different measurement problem than a hundred campaigns a quarter, and a different audit problem than the campaign-era stack was built to answer.
The functions do not disappear. Their relative weight shifts. The headcount stays roughly the same. The skill mix changes. The org chart redraws.
The CMO's new mandate
Three things become the CMO's primary job in the decisioning era.
Brand stewardship. The agent runs the brand voice. The brand voice the agent runs has to be defined, monitored and policed by humans. The CMO is more brand-anchor than campaign-leader. Creative direction at the strategic level becomes more important. Creative production at the campaign level becomes less.
Decision architecture. Whether the customer's moment is met or missed depends on what the platform can do. The CMO who briefed the campaign now briefs the architecture. The procurement decision is now a marketing decision, and a larger one than it used to be.
Hiring the agent. Not literally hiring. Procuring the agent capability that operates the brand at scale. The buying decision moves from campaign tools to agent platforms. The buying discipline moves from feature-checklist to value engineering, audit and accountability.
The CMO of the decisioning era is not running campaigns. They are hiring the agents that run them.
| Function | Campaign era | Decisioning era |
|---|---|---|
| Campaign management | High weight. Project leads, vendor management, end-to-end campaign delivery. | Low weight. The agent runs the campaign at the unit level; the function moves up to setting the brief. |
| Segment building | High weight. Analyst teams assembling audiences by hand from segmented data. | Near zero. The agent composes context dynamically, on signals that are live. |
| Creative direction | Distributed across campaigns. Production heavy. Agency-led. | Concentrated at the strategic level. Brand voice and tone definition; production is largely model-assisted. |
| Channel performance | High weight. Channel-by-channel tuning, paid-media bidding, attribution by channel. | Transformed. Measured at the decision level, not the channel level. The channel is one of several outputs. |
| MarTech ops | High weight. Running the stack, integrations, vendor coordination. | Transformed. Evaluating agent platforms, governing model risk, configuring decision policy. |
| Analytics | Campaign-level outcomes. MMM, MTA, post-campaign attribution. | Decision-level outcomes. Audit-ready evidence at every interaction. Population-level oversight. |
What the agency relationship becomes
For thirty years, the CMO's most important outside relationship has been with the agency. The agency held the creative brief, the campaign production, the channel buying expertise and often the institutional memory of what had worked and what had not. In some markets the agency carried more brand history than the brand team itself.
The agent era changes that relationship. Agencies that were principally campaign-production organisations are competing with agents that produce campaigns at unit cost. Agencies that were principally strategic-counsel organisations are competing for a smaller pool of strategic work and a smaller share of the CMO's time. The agencies that survive move up the value chain into brand stewardship, decision architecture and agent governance, or they move down into specific creative craft where the agent cannot yet compete. The agencies that do neither tend not to make the next renewal.
The CMO who is not already having this conversation with their agency partners is already late to it. The conversation is happening with or without them.
The CMO who tries to keep the campaign model
Some CMOs will try to use agents inside the existing campaign framework. The agent becomes a feature inside the campaign tool. The agent's output is treated as another marketing artefact, reviewed at the next campaign post-mortem. This is the version theatre-grade buying discipline tends to produce. The brand the agent runs is still running on the agency's brief from last quarter. The agent makes the same mistake faster and at scale.
The CMO who treats the agent as a tool inside the campaign era's operating model gets a faster version of the campaign era's mistakes. The CMO who treats the agent as the operating model gets the agent era's possibilities. The choice between the two is the procurement decision the next twelve months will be made on.
What follows
The agent platforms that operate the brand at scale have four properties most campaign-era tools lack: an open architecture the operator can read and audit on its own terms; reason-coded decision logs as a by-product of every decision, exportable in the regulator's format; outcomes-aligned pricing against decisions made rather than seats licensed; and operator-controlled deployment, so neither the customer's data nor the audit trail crosses a vendor's boundary. The CMO who briefs for these properties is buying for the operating model that is arriving. The CMO who briefs for the feature list is buying for the one that is closing.
