The correct answers are B, C, and D because they reflect the core functional expectations of an effective Management of Change (MOC) system as defined by CCPS.
Option B is correct because MOC must ensure that appropriate risk controls are identified and implemented before a change is executed. This includes evaluating hazards and ensuring safeguards are in place to prevent incidents.
Option C is also correct because changes often impact multiple RBPS elements (e.g., procedures, training, mechanical integrity), and an effective MOC system ensures that all affected work processes are updated accordingly .
Option D is essential because MOC requires involvement from qualified personnel across disciplines (engineering, operations, safety) to properly evaluate technical and operational impacts of the change.
Option A is incorrect because while MOC contributes to incident prevention, it does not guarantee elimination of all incidents. Option E is incorrect because MOC is primarily risk-based and safety-driven , not governed by general quality assurance considerations.
CCPS emphasizes that effective MOC systems are systematic, multidisciplinary, and risk-focused , ensuring that all changes are thoroughly evaluated and safely implemented.
