• B. Notify stakeholders and adjust plans; reallocate resources as needed.
• C. Cancel all missions.
• D. Maintain the original plan without changes.

Answer: (B)

When a supplier cannot deliver on time, the best action is to notify stakeholders and adjust plans; reallocate resources as needed. This approach keeps everyone informed about the impact, allowing coordinated decision-making and reducing the risk of cascading delays. By updating schedules and shifting resources—such as deferring nondependent tasks, reassigning personnel, or using alternate suppliers or workarounds—you preserve mission readiness and minimize wasted time and effort. Ignoring the delay, canceling all missions, or sticking to the original plan without changes would magnify risk and waste, whereas proactive communication and flexible resourcing create the least disruption and the quickest path back to an aligned, achievable plan.
