Start with a work map, not a headcount plan.
When AI begins to take on marketing execution, it is easy to begin with whether a team should disappear. That question comes too early. The first document should be a work map: which tasks can be automated at the drafting, summarizing or repeat-execution stage, and which still require a person to approve and explain the outcome.
Public research shows that marketing and sales are among the functions where generative AI is commonly used. Common examples include content drafts, personalized messages, SEO support and customer-service assistance. McKinsey’s 2023 estimate puts the potential value in marketing at 5 to 15 percent of total marketing spend. That is a modeled potential across selected use cases, not a guaranteed cost reduction or a company result.
Using a tool is not the same as redesigning an organization. In McKinsey’s 2025 global survey, 21 percent of respondents at organizations using gen AI said their organizations had fundamentally redesigned at least some workflows. It is a global self-report, not evidence about every company or marketing team. It does show that roles, approval paths and measurement do not change automatically when an AI tool is introduced.
Separate tasks before you separate job titles.
The acceptable degree of automation changes with data sensitivity, customer impact and the cost of error. The useful distinction is not whether automation exists, but where human review and explanation must remain visible.
| Category | Examples | Human role |
|---|---|---|
| Automation or assistance candidates | Content and copy drafts, translation and summarization, variants, basic FAQ drafts, data preparation and report skeletons | Set the purpose and inputs; decide whether the result can be released externally. |
| Final-review and collaboration candidates | Approving or rejecting brand messages, channel and budget priorities, crisis response, legal or partner coordination and external explanation | Record the basis for the choice and decide who can revise or stop when exceptions arise. |
Using a tool and redesigning how work operates are different acts.
Three paths for redesigning operations.
These are not mutually exclusive organization charts. They are operating paths that can be considered in light of a team’s current capabilities, data and approval systems. The point is not to choose a universal answer, but to identify the team’s current position and its next preparation.
| Path | What changes | When it may fit | Watch for |
|---|---|---|---|
| A. Tool alongside the team | Keep roles intact and add assistance for drafting, translation and summarization. | Pilots or individual productivity experiments | If the workflow stays unchanged, duplicate work and inconsistent brand tone can remain. |
| B. Workflow redesign | Redraw campaign, content and lead-management stages, inputs and approval points. | When a team can invest in shared rules and transition costs | Without managing role conflict and transition costs, the organization may only add tools. |
| C. Mixed operation | Automate repeat execution while explicitly retaining human handling of high-risk approval, exceptions and external explanation. | When data criteria, quality review and shared measures can be maintained | Vague review criteria can weaken quality and brand consistency. |
Four questions for the next meeting.
1. Which tasks will we test for automation or assistance this quarter? 2. Which tasks cannot go outside the company without final human approval? 3. Are the owner and timing from draft to review to release documented? 4. Are we treating “reduce headcount” and “reassign work” as the same question?
This is not an argument for eliminating a marketing team. It is a proposal to rewrite what remains after AI enters the workflow in terms of actual tasks and approval paths, not abstract job titles.
Scope and limitations.
This essay does not present a Korean case of marketing-organization redesign. It does not generalize international research to every Korean company, and McKinsey’s findings are survey responses and modeled estimates—not proof of a particular company’s result or headcount reduction. This is not legal or employment advice.
