RAM Communication & Documentation 2

Question 1

Which document formally authorizes a maintenance team to perform corrective work on a critical system?

Accepted Answer

Work order

Answer

A work order is the formal authorization document that directs and permits maintenance personnel to perform specific repair or corrective tasks.

Question 2

In RAM documentation, what does the acronym MTTR specifically measure?

Accepted Answer

Mean Time To Repair

Answer

MTTR stands for Mean Time To Repair and quantifies the average time needed to restore a failed component or system to operational status.

Question 3

A RAM engineer needs to communicate the probability that a system will be operational at any random moment. Which metric should be reported?

Accepted Answer

Instantaneous availability

Answer

Instantaneous (or point) availability expresses the probability that a system is functioning at a specific point in time, which is what the engineer needs to report.

Question 4

Which type of report is BEST used to communicate trends in equipment reliability over successive operating periods?

Accepted Answer

Reliability growth trend report

Answer

A reliability growth trend report tracks changes in failure rates or MTBF across multiple periods, enabling teams to see whether reliability is improving or degrading.

Question 5

When documenting a failure in a maintenance management system, which information is LEAST essential for a RAM analysis?

Accepted Answer

Technician's employee ID number

Answer

The technician's employee ID is an administrative detail; RAM analysis relies on failure mode, detection time, and operating hours to compute reliability metrics.
