The sponsor is concerned scope isn't being met and has questioned team members individually. You discover the sponsor and team interpret the scope differently. What should you do?

The correct answer is to facilitate a stakeholder alignment session. This directly addresses the root cause: differing interpretations of scope. A dedicated session allows for open discussion, clarification of expectations, and negotiation to reach a shared understanding and agreement on deliverables. This proactive approach prevents further misunderstandings and ensures everyone is working towards the same goal. Starting a daily standup is insufficient as it doesn't address the fundamental disagreement on scope. Having the team produce a scope document is reactive and may not resolve the underlying conflict if the sponsor's initial understanding differs significantly. Asking the team to change deliverables without discussion is autocratic and ignores the team's perspective, potentially leading to resentment and further issues.
