CMRP Maintenance Management — Questions and Answers
Question 1: What is a CMMS and what is its primary purpose?
- A chemical monitoring system
- A Computerized Maintenance Management System for organizing, planning, and tracking maintenance activities (Correct answer)
- A customer management system
- A communications monitoring system
Correct answer: A Computerized Maintenance Management System for organizing, planning, and tracking maintenance activities
A CMMS is software that helps maintenance departments manage work orders, schedule preventive maintenance, track assets, manage inventory, and analyze maintenance data.
Question 2: What is the difference between planned and unplanned maintenance?
- There is no practical difference
- Planned maintenance is scheduled in advance; unplanned maintenance responds to unexpected breakdowns (Correct answer)
- Planned maintenance costs more
- Unplanned maintenance is more effective
Correct answer: Planned maintenance is scheduled in advance; unplanned maintenance responds to unexpected breakdowns
Planned maintenance allows for preparation (parts, tools, labor scheduling), while unplanned maintenance reacts to failures, typically costing 3-5 times more due to urgency and downtime.
Question 3: What is a maintenance backlog?
- Excess spare parts
- The accumulation of approved maintenance work that has not yet been completed (Correct answer)
- A type of maintenance record
- Old maintenance manuals
Correct answer: The accumulation of approved maintenance work that has not yet been completed
The maintenance backlog represents all known work that needs to be done but has not been completed. Managing backlog is critical for ensuring equipment reliability.
Question 4: What Key Performance Indicator (KPI) measures the percentage of time equipment is available for use?
- MTTR
- Availability rate — calculated as (available time / total time) × 100% (Correct answer)
- OEE
- Utilization rate
Correct answer: Availability rate — calculated as (available time / total time) × 100%
Equipment availability measures the proportion of time that equipment is in a condition to perform its intended function, excluding downtime for maintenance and repairs.
Question 5: What is the purpose of a maintenance work order?
- To order new equipment
- To authorize, document, and track specific maintenance tasks including labor, materials, and completion (Correct answer)
- To request a day off
- To order office supplies
Correct answer: To authorize, document, and track specific maintenance tasks including labor, materials, and completion
Work orders formally authorize maintenance work and serve as the primary document for tracking what was done, who did it, what parts were used, and how long it took.
Question 6: What is Total Productive Maintenance (TPM)?
- A maintenance cost tracking system
- A holistic maintenance philosophy involving all employees to maximize equipment effectiveness and eliminate waste (Correct answer)
- A type of insurance policy
- A brand of maintenance tools
Correct answer: A holistic maintenance philosophy involving all employees to maximize equipment effectiveness and eliminate waste
TPM engages all employees, from operators to management, in proactive and preventive maintenance to achieve zero breakdowns, zero defects, and zero accidents.
