Start with the buyer's world, not the existing content
Research customer needs before content revision by first mapping the buyer context around the problem. Validate the brief with open questions: what is happening in the customer's world, what pressures shape the decision, and what may sit beneath the stated request? Treat internal views from sales, product and marketing as useful questions to test, not final answers.
Then speak directly with customers and people who interact closely with the intended audience. Listen for concerns, ambitions, demands and the practical situations that make a capability matter. Give people room to describe their experience in their own terms, including the parts that do not fit the original assumptions. Customer insight becomes more useful when it captures how people experience the offer, not only how the business describes it. That is the difference between a content refresh that changes wording and one that brings genuine clarity.
