Your question is Pivoting Program Strategy. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe a time you had to pivot a program strategy due to an unforeseen technical constraint. Use a real program example and explain the constraint, its impact on scope, schedule, or quality, and how you aligned stakeholders around the revised approach. Be specific about your decisions, trade-offs, execution plan, and measurable outcome.
