Use ChatGPT Work to turn approved market evidence, operating constraints, cost and markup assumptions, and business objectives into a strategy-options memo: separate what the research says from what the team assumes, expose tradeoffs in segment, position, channel, offer, and economics, and name the tests that would change the recommendation. It can organize a decision; it cannot manufacture demand, infer people from thin signals, validate a claim, set a price, commit spend, or launch a campaign. The attached figures are projected role-task priors, not measured ChatGPT adoption by marketing managers, so they support a bounded planning trial rather than a claim about current practice.
