If preventative maintenance is effective, ___ maintenance will be greatly reduced.

• A. Emergency
• B. Repair
• C. Corrective
• D. Predictive

Answer: (D)

Preventive maintenance is about keeping equipment in good condition on a regular schedule so failures don’t occur. When this approach works well, there are fewer faults to anticipate, so the need for monitoring a system’s condition to predict exactly when a failure will happen is reduced. In other words, with strong preventative care, the drive to run data-driven checks and plan maintenance based on predicted failure windows decreases, making predictive maintenance less frequent.

It’s worth noting that emergency and corrective maintenance would also tend to drop as equipment stays healthier, but the statement points to the reduction in the use of predictive, data-driven maintenance methods specifically.
