A team is about to start a project with a customer who was difficult previously because they could not clearly specify what they wanted. What approach should the project manager take to remove this impediment?

The correct approach is to work with the product owner to define the minimum viable product(s) (MVP). When a customer struggles to define requirements, an agile approach focusing on MVPs allows for iterative development and frequent feedback. This helps clarify needs incrementally, reducing the risk of rework and ensuring the customer gets value early. Using a predictive approach to obtain formal acceptance for each deliverable might exacerbate the problem, as the customer still struggles with initial definition, leading to potential delays and dissatisfaction. Improving negotiation and soft skills is beneficial but doesn't directly address the core issue of unclear requirements. Creating and monitoring a schedule with due dates is a project management tool, but it won't resolve the underlying problem of undefined scope.
