Zero Based Maintenance is the maintenance approach that

• A. Maintenance approach that starts from scratch and justifies every task.
• B. Standards for maintenance and integrity applications.
• C. Training using interactive software for oil industry professionals.
• D. The flow of information within an organization.

Answer: (A)

Zero Based Maintenance requires you to justify every maintenance task from zero in each planning cycle. It treats maintenance planning as a clean-sheet exercise, re-evaluating each activity’s necessity, safety impact, risk reduction, cost, and overall benefit to reliability. If a task doesn’t pass this rigorous justification, it’s dropped or reworked rather than carried forward from the previous plan. This prevents waste, reduces unnecessary work, and ensures resources go to activities with proven value.

The other options describe standards for maintenance and integrity applications, training using software, or the flow of information within an organization. While those are important topics, they don’t define the practice of evaluating and validating every maintenance task from scratch. Therefore, starting from zero and justifying every task is the hallmark of Zero Based Maintenance.
