CMRT Maintenance Planning and Scheduling 1 — Questions and Answers
Question 1: What is the primary purpose of a work order in a maintenance management system?
- To document, authorize, and track maintenance work from initiation to completion (Correct answer)
- To record employee attendance during maintenance shifts
- To order replacement parts from suppliers
- To schedule vacation time for maintenance technicians
Correct answer: To document, authorize, and track maintenance work from initiation to completion
A work order is the central document that authorizes, tracks, and records all details of a maintenance job including labor, materials, and cost.
Question 2: What does the acronym CMMS stand for in the context of maintenance management?
- Corrective Maintenance Management Strategy
- Computerized Maintenance Management System (Correct answer)
- Critical Machine Monitoring Software
- Component Maintenance and Monitoring Schedule
Correct answer: Computerized Maintenance Management System
CMMS stands for Computerized Maintenance Management System, a software platform used to manage work orders, assets, inventory, and maintenance schedules.
Question 3: A maintenance planner is developing a job plan for replacing a pump seal. Which element is MOST critical to include in the job plan?
- The name of the supervisor who approved the job
- A detailed list of required materials, tools, and step-by-step task instructions (Correct answer)
- The cost center to which the labor will be charged
- The date the equipment was originally purchased
Correct answer: A detailed list of required materials, tools, and step-by-step task instructions
A comprehensive job plan must include materials, tools, safety requirements, and step-by-step procedures so the technician can execute the work efficiently without interruption.
Question 4: In maintenance planning, what does 'wrench time' measure?
- The torque applied to fasteners during repair
- The time technicians spend actively performing hands-on maintenance work (Correct answer)
- The scheduled maintenance interval for torque-sensitive components
- The time required to procure specialty wrenches for a job
Correct answer: The time technicians spend actively performing hands-on maintenance work
Wrench time (also called tool time) measures the percentage of a technician's day actually spent performing direct maintenance work, excluding travel, waiting, and administrative tasks.
Question 5: What is the recommended target range for a healthy maintenance work order backlog?
- 0 to 1 week of work
- 2 to 4 weeks of available crew work (Correct answer)
- 6 to 8 weeks of available crew work
- More than 12 weeks of available crew work
Correct answer: 2 to 4 weeks of available crew work
A backlog of 2 to 4 weeks of crew work is generally considered healthy — enough work to keep crews busy and allow efficient scheduling without becoming unmanageable.
Question 6: Which of the following BEST describes the difference between a maintenance planner and a maintenance scheduler?
- The planner determines what work needs to be done and how; the scheduler determines when and who will do it (Correct answer)
- The planner manages the parts room; the scheduler manages labor payroll
- The planner approves work orders; the scheduler closes them after completion
- The planner works on reactive jobs; the scheduler works on preventive jobs only
Correct answer: The planner determines what work needs to be done and how; the scheduler determines when and who will do it
The planner defines the scope, materials, tools, and procedures for a job (the 'how'), while the scheduler coordinates timing, crew assignment, and sequencing (the 'when and who').
Question 7: What is a maintenance 'shutdown' or 'turnaround' primarily used for?
- Permanently decommissioning aging equipment
- Performing major inspections, overhauls, and capital work that cannot be done while equipment is running (Correct answer)
- Training new maintenance technicians on equipment operation
- Conducting environmental compliance audits
Correct answer: Performing major inspections, overhauls, and capital work that cannot be done while equipment is running
Shutdowns/turnarounds are planned outage events where major maintenance, inspections, and upgrades are concentrated because the work requires equipment to be offline.
