What does MBCS stand for?

• A. Modification Baseline Configuration System
• B. Modification Baseline Control System
• C. Maintenance Baseline Control System
• D. Modification Baseline Calibration System

Answer: (B)

This question tests how ECMS terminology conveys the role of a system that governs changes to the project baseline. MBCS stands for Modification Baseline Control System, with M meaning Modification, B Baseline, C Control, and S System. That combination signals a platform that manages and enforces changes to the baseline, including proposing, approving, and tracking modifications so the baseline remains consistent. The other options introduce Calibration, Configuration, or Maintenance, which shift the meaning away from controlled change governance, so they don’t fit the established terminology. So Modification Baseline Control System is the correct expansion.
