Which statement about a system's baseline data is true?

• A. Baseline data is a record of all the system performance specifications when the system is operating as designed.
• B. Baseline data is a log of past outages.
• C. Baseline data is a summary of warranty terms.
• D. Baseline data is a forecast of future maintenance costs.

Answer: (A)

Baseline data serves as the reference snapshot of how the system should perform when everything is operating as designed. It records the expected performance specifications—temperatures, pressures, flow rates, energy usage, run times—under normal conditions. Having this benchmark lets you detect deviations, diagnose faults, and assess efficiency by comparing current data to the baseline. A log of past outages is historical incident data and doesn’t define normal performance. A summary of warranty terms relates to coverage, not how the system runs. A forecast of future maintenance costs is a projection, not the actual performance snapshot used for monitoring. So, the true statement is that baseline data is a record of the system’s performance specifications when it is operating as designed.
