• B. It is a one-time planning method for projects.
• C. It is a routine instruction manual.
• D. It is a financial audit framework.

Answer: (A)

PDCA is a cycle for ongoing improvement in maintenance. Plan what change to make and how you’ll measure success, Do the change on a small scale or in a controlled way, Check the results by comparing actual performance to expectations, and Act to standardize the successful improvement or start another cycle to tackle remaining issues. In maintenance this drives iterative refinement of processes, such as updating preventive maintenance tasks, adjusting lubrication intervals, or changing inspection procedures based on real data like uptime, failure rate, or repair costs. Because it’s a loop, the goal is continuous betterment rather than a one-time plan, a static manual, or an auditing framework.
