Two-Person Control is best described as which concept?

• A. Two-Person Control
• B. Dual-Person Oversight
• C. Multi-Operator Control
• D. Single-Person Control

Answer: (A)

Two-Person Control means that for certain critical actions, two authorized individuals must participate and cooperate to proceed. Each person provides independent verification, often with separate credentials and roles, so no single operator can initiate and complete the action alone. This setup creates accountability, reduces the chance of misuse or mistakes, and provides an auditable trail of who authorized and carried out the step. In practice, one person may start the action while the second confirms or executes a dependent step, and both must be present for the task to be completed. This is used to safeguard high-risk assets and ensure policy compliance.

The other terms don’t fit as well because they either describe a similar idea with different wording or imply more than two participants, or allow a single person to act alone, which defeats the purpose of requiring a second party.
