A critical scope issue late in a project (week 9 of 12) is a governance and decision-rights matter that typically requires immediate escalation to the executive sponsor . The executive sponsor owns accountability for aligning the project with organizational priorities, approving major trade-offs, and authorizing changes that affect the “triple constraint” (scope, time, cost) and risk exposure. Scheduling an immediate executive sponsor meeting (C) enables timely decisions such as: whether to defer the scope item to a later phase, adjust requirements, approve additional resources, change timeline, or accept residual risk. This prevents uncontrolled scope creep and protects project outcomes.

Merely highlighting the issue on a weekly status report (A) increases visibility but does not ensure a timely decision, especially when the issue is critical and time-sensitive. Adding it to the next team meeting (B) is insufficient because the team may not have authority to change scope or timeline. Automatically delaying go-live to expand scope (D) is premature and may be inappropriate without sponsor approval and impact analysis. Because the communication plan explicitly includes executive sponsor meetings as needed , a critical scope issue is exactly the trigger for immediate sponsor engagement.
