CMRP PRACTICE QUESTIONS
WITH CORRECT ANSWERS
Replacement Asset Value (RAV) - ....ANSWER ...-defined as the cost that
would be incurred, in today's dollars, to replace the facility and equipment in its
current configuration.
Overall Equipment Effectiveness (OEE) definition - ....ANSWER ...-metric
for measuring how well a process is operating by evaluating the three major
process components: availability, performance efficiency (rate/speed) and quality.
The process can be a single piece of equipment, a manufacturing cell, a production
line or a plant
Overall Equipment Effectiveness (OEE) equation - ....ANSWER ...-
Availability × Performance Efficiency × Quality
Availability - ....ANSWER ...-defined as the percentage of time that the
process is actually operating (uptime) compared to when it is scheduled to operate
Performance efficiency (rate/speed) - ....ANSWER ...-defined as the
percentage of Actual Run Rate/Cycle Time to the Best Run Rate/Cycle Time
....COPYRIGHT ©️ 2025 ALL RIGHTS RESERVED...TRUSTED & VERIFIED 1
,Quality - ....ANSWER ...-defined as the percentage of "First Pass, First
Time" Saleable Production to the Actual Production
Actual Production - ....ANSWER ...-total quantity of production produced
in the given time period, regardless of its quality
Lagging Indicator - ....ANSWER ...-An indicator that measures performance
after the business or process result starts to follow a particular pattern or trend
Leading Indicator - ....ANSWER ...-An indicator that measures performance
before the business or process result starts to follow a particular pattern or trend
Three (3) sets of measurable components that make up the maintenance and
reliability process - ....ANSWER ...-1. Management processes and behaviors
(mission and vision, people skills)
2. Operational execution (operations, design and maintenance)
3. Manufacturing performance (availability, quality, cost and benefits)
mean metrics - ....ANSWER ...-metrics that describe the Reliability,
Availability and Maintainability (RAM) characteristics of a component, asset or
even facility
Inherent Availability - ....ANSWER ...-measure of the variables inherent in
the design that affect availability. In the calculation of downtime, it usually includes

, only active repair time. It does not include preventive maintenance time and
administrative or logistic delays, but does include corrective maintenance
downtime
Inherent Availability Formula - ....ANSWER ...-Ai = MTBF / (MTBF +
MTTR)
Where MTBF = Mean Time Between Failures
And MTTR = Mean Time to Repair (corrective maintenance only)
Achieved Availability - ....ANSWER ...-probability that an item, when used
under design conditions in an ideal support environment, will perform
satisfactorily. It includes both active repair time and preventive maintenance time,
but excludes administrative and logistic delay times
Achieved Availability Formula - ....ANSWER ...-Aa = MTBM / (MTBM +
MDTM)
Where MTBM = Mean Time Between Maintenance
And MDTM = Mean Downtime for Maintenance
Operational Availability - ....ANSWER ...-probability that an item, when
used under design conditions in an operational environment, will perform
satisfactorily. It includes active repair time, preventive maintenance time and
