Which two codes serve as bases for maintenance data reporting and maintenance control procedures?

• A. MCN and JCN
• B. MCN and WUC
• C. JCN and WUC
• D. OPNAV Form 4790/60 and VIDS

Answer: (A)

Maintenance data reporting and maintenance control procedures rely on two identifiers that track work from start to finish. The Maintenance Control Number acts as the umbrella identifier for the overall maintenance action, allowing all related tasks, material, labor, and costs to be grouped and reported together. The Job Control Number is assigned to each specific job or task within that action, providing a precise hook to monitor progress, assign work, and record detailed status updates. Using both together lets data systems link the overall maintenance effort to its individual tasks, so reports can show both the big picture and the granular work completed. The other options don’t serve this combined role: Work Unit Codes classify the type of work but aren’t the primary basis for reporting and control; the form itself is a documentation tool, and VIDS is a separate data system rather than a coding basis.
