Which term is abbreviated as O&M and is used for manuals detailing operation and maintenance procedures?

• A. Organizational and Maintenance Manual
• B. Operations and Monitoring Manual
• C. Operational and Maintenance Manual
• D. Organizational Mission Manual

Answer: (C)

O&M refers to the procedures for operating and maintaining a system. A manual that covers how to run the equipment and perform upkeep is described as an Operational and Maintenance Manual, since it uses operational guidance together with maintenance instructions to support everyday use and upkeep. The other options misdirect the scope: Organizational and Maintenance Manual implies governance or structure rather than how to operate; Operations and Monitoring Manual adds monitoring content that isn’t part of standard operation and upkeep; Organizational Mission Manual focuses on purpose rather than the practical procedures. So the term that best matches the intended manuals detailing how to operate and maintain equipment is Operational and Maintenance Manual.
