Your question is Critical Path and S-Curves Case. 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).
Walk me through an analysis of a Gantt chart and an S-curve, including what you would do when you see issues.
Explain the indicators you would review, how you would distinguish symptoms from root causes, and how you would communicate corrective actions. Address schedule, resource, dependency, cost, and forecasting implications.
