CAPM Practice: Determine how to document project controls of predictive, plan-based projects

A project manager is presenting the project status to the steering committee. The project shows: SPI = 0.81, CPI = 0.87, with 4 months remaining. The project manager proposes two options: Option A — crash the remaining critical path to recover schedule ($120,000 additional cost); Option B — reduce scope by removing 3 non-critical deliverables (saves $80,000, recovers 6 weeks of schedule). What information does the steering committee MOST need to make this decision?
