In preventive maintenance planning, which activity is most characteristic?

• A. Random improvisation
• B. Regular inspections and servicing
• C. Waiting for failures
• D. Replacing parts on a fixed calendar no matter what

Answer: (B)

Preventive maintenance planning is about actively caring for equipment on a schedule to prevent failures. The hallmark is performing regular inspections and servicing. By setting defined intervals for checks, lubrication, adjustments, part replacements as needed, and routine cleaning, you gather data, catch wear early, and keep systems operating reliably. This proactive rhythm reduces unexpected downtime, helps manage costs, and supports reasoned decisions about when to service or replace components. In contrast, random improvisation lacks structure, waiting for failures is reactive, and replacing parts on a rigid calendar without considering actual condition can waste resources or miss real wear patterns. Regular inspections and servicing capture the essence of planning maintenance to maintain performance.
