1. 1What is the main purpose of an O&M mission statement when setting maintenance direction?

   1. A. To replace the facility's equipment procedures
   2. B. To align program goals with site management goals
   3. C. To define every technician's daily work order
   4. D. To calculate each asset's remaining useful life

   Answer: B

   Explanation: The DOE guide states that "The main objective is to align the program goals with those of site management and to seek approval, recognition, and continued support." Thus the mission statement connects maintenance direction to the organization's goals.

2. 2Which three flows belong on a manufacturing current-state value stream map?

   1. A. Material, process, and information flows
   2. B. Material flow alone, excluding process and information
   3. C. Process steps alone, excluding material and information
   4. D. Information flow alone, excluding material and process

   Answer: A

   Explanation: NIST's mapping steps include "Develop the current state map of materials, processes and flow of information". These flows define how the process currently operates.

   Reference: Value Stream Mapping — Value stream mapping, four steps

3. 3In a reliability expectation stated as MTBF, what does MTBF measure?

   1. A. Mean time between failures
   2. B. Mean time to repair or replace
   3. C. Mean downtime per maintenance action
   4. D. Mean preventive maintenance duration

   Answer: A

   Explanation: NASA defines "MTBF = Mean Time Between Failure (also, Mean Time to Failure)" in its availability discussion. It represents the reliability side of the expectation.

   Reference: NASA Reliability-Centered Maintenance Guide for Facilities and Collateral Equipment — Section 14.3, page 14-4

4. 4When determining maintenance staffing requirements, what should the available personnel by craft be compared with?

   1. A. Last year's staffing totals without the current work plan
   2. B. The work in the plan, its priorities, and available alternatives
   3. C. The number of authorized positions without comparing required craft hours
   4. D. The total backlog count without considering craft or work priority

   Answer: B

   Explanation: NASA states, "The personnel resources available in each craft should closely match the amount of work included in the AWP, taking into consideration work priorities and alternative methods of accomplishment." Staffing follows the work plan and priorities.

   Reference: NASA NPR 8831.2F, Chapter 3: Maintenance Management — Section 3.6.2.1, Workload Balance

5. 5Which proactive, condition-based input can generate maintenance work beyond recurring preventive tasks?

   1. A. Condition assessments and predictive testing
   2. B. A breakdown report after equipment stops
   3. C. A scheduled preventive task reaching its calendar date
   4. D. A customer request unrelated to measured equipment condition

   Answer: A

   Explanation: NASA says that much nonrecurring maintenance work "is generated from the facility condition assessment program and predictive testing". These findings are legitimate work-identification inputs.

   Reference: NASA NPR 8831.2F, Chapter 5: Facilities Maintenance Program Execution — Section 5.3.3, Facilities Condition Assessment Program

6. 6When defining the O&M program's direction, what should its measure of success address?

   1. A. Metrics tied to program goals
   2. B. Only the count of open work orders
   3. C. Only the age of installed equipment
   4. D. Only the size of the maintenance staff

   Answer: A

   Explanation: The DOE mission statement prompts ask, "Finally, how do we measure success – what metrics do we use". The guide then gives examples of outcome metrics. Measures of success should therefore express intended program results, not a single incidental count.

   Reference: Operations & Maintenance Best Practices Guide: Release 3.0 — Chapter 3, section 3.3.1, page 3.3

7. 7Which two specifications should a manufacturing process measurement plan make explicit?

   1. A. The characteristic measured and how often data are collected
   2. B. The characteristic measured but no collection frequency
   3. C. The collection frequency but no measured characteristic
   4. D. The tolerance target but neither measure nor frequency

   Answer: A

   Explanation: The DOE eGuide says a measurement plan includes "specification of the systems, processes or equipment to be monitored or measured" and "the frequency of data collection". These define which process parameters are observed and when.

   Reference: AMO eGuide: Step 4.1 — Step 4.1.8, define and implement an energy measurement plan

8. 8When setting a maintainability expectation for equipment, what does MTTR refer to?

   1. A. Mean time to repair or replace
   2. B. Mean time between failures
   3. C. Mean time between all maintenance
   4. D. Mean total operating time

   Answer: A

   Explanation: NASA specifies "MTTR = Mean Time to Repair or Replace". It is the repair-time term in the inherent availability relationship, distinct from time between failures.

   Reference: NASA Reliability-Centered Maintenance Guide for Facilities and Collateral Equipment — Section 14.3, page 14-5

9. 9Why should skill requirements be reviewed when new maintenance technology enters the program?

   1. A. Keep the original skill profile even when tools and methods change
   2. B. Assume equipment vendors will perform all newly required analysis
   3. C. Personnel must maintain the skills needed to carry out the program
   4. D. Use staffing totals as a substitute for checking technical skill needs

   Answer: C

   Explanation: NASA says the organization "should ensure that personnel have and maintain the skills needed to cope with changing technology to effectively carry out the facilities maintenance program." Skill needs must follow the work technology.

   Reference: NASA NPR 8831.2F, Chapter 3: Maintenance Management — Section 3.6.2.2, Education and Training

10. 10Why assign a unique identifier to each maintenance work item at reception?

    1. A. To set its final labor cost before planning
    2. B. To track it from planning through completion and history
    3. C. To eliminate the need for work authorization
    4. D. To guarantee that the item will be approved

    Answer: B

    Explanation: NASA explains that the identifier "permits tracking the work item through its life cycle of planning, approval as a work order, execution, and historical documentation." It supports traceability, not automatic approval.
