Leading a hybrid innovation project, the project manager discovers requirements are unclear during a meeting with the sponsor and key stakeholders. What should the project manager do?

The project manager should help the sponsor and major stakeholders craft the product vision because a clear vision is fundamental to defining and refining requirements, especially in an innovation project where initial requirements are often ambiguous. This proactive approach directly addresses the root cause of unclear requirements. Asking the sponsor to meet with the product owner delegates a critical leadership responsibility and doesn't guarantee a solution. Recording it as a risk and monitoring it is passive; the project manager should actively work to resolve the ambiguity. Reviewing lessons learned might offer insights but doesn't solve the immediate problem of defining the current project's vision and requirements.
