MMC Work Order Management & Documentation 2 — Questions and Answers
Question 1: What is the primary advantage of using a Computerized Maintenance Management System (CMMS) for work order management?
- It eliminates the need for skilled maintenance technicians
- It centralizes data, improves tracking, and generates performance reports automatically (Correct answer)
- It reduces the total number of preventive maintenance tasks required
- It automatically purchases and receives spare parts
Correct answer: It centralizes data, improves tracking, and generates performance reports automatically
A CMMS centralizes all maintenance data, provides real-time work order tracking, and automatically generates performance reports to support management decision-making.
Question 2: Which document provides detailed step-by-step instructions that should accompany a work order for complex maintenance tasks?
- Purchase order
- Standard Operating Procedure (SOP) or Job Plan (Correct answer)
- Material Safety Data Sheet (MSDS)
- Equipment warranty card
Correct answer: Standard Operating Procedure (SOP) or Job Plan
Standard Operating Procedures or job plans provide the detailed, pre-engineered step-by-step instructions that technicians follow when executing complex maintenance work orders.
Question 3: What information should be captured when closing out a completed work order?
- Only the technician's name and completion date
- Actual labor hours, parts used, findings observed, and actions taken (Correct answer)
- The next scheduled oil change date for the equipment
- Customer satisfaction survey results
Correct answer: Actual labor hours, parts used, findings observed, and actions taken
Proper work order close-out must capture actual labor hours, materials consumed, findings observed, and corrective actions taken to build a valuable maintenance history record.
Question 4: How does thorough work order documentation support root cause analysis (RCA)?
- It provides historical failure data to identify recurring patterns and underlying causes (Correct answer)
- It automatically generates repair solutions for future failures
- It assigns accountability to specific technicians for failures
- It eliminates the need for formal RCA investigations
Correct answer: It provides historical failure data to identify recurring patterns and underlying causes
Detailed historical work order records provide the failure data and maintenance history needed to identify patterns, recurring failures, and underlying root causes of equipment problems.
Question 5: What does the maintenance KPI 'wrench time' measure?
- The number of work orders generated per month
- The percentage of a technician's shift spent performing actual hands-on maintenance work (Correct answer)
- The average cost per work order completed
- The ratio of emergency to planned work orders
Correct answer: The percentage of a technician's shift spent performing actual hands-on maintenance work
Wrench time measures the percentage of a technician's available shift time spent on actual hands-on maintenance work, with world-class targets typically ranging from 55 to 65 percent.
Question 6: Which metric measures the proportion of planned versus reactive maintenance work orders?
- Mean Time Between Failures (MTBF)
- Planned maintenance percentage or proactive maintenance ratio (Correct answer)
- Overall Equipment Effectiveness (OEE)
- Return on Investment (ROI)
Correct answer: Planned maintenance percentage or proactive maintenance ratio
The planned maintenance percentage measures what proportion of total work is planned/preventive versus reactive/emergency, with world-class targets often cited at 80 to 90 percent planned.
Question 7: What is the primary benefit of linking work orders to specific equipment records in a CMMS?
- It automatically orders replacement equipment when failures occur
- It builds equipment maintenance history and enables tracking of total maintenance costs per asset (Correct answer)
- It schedules employee training programs for specific equipment types
- It generates customer invoices for maintenance services performed
Correct answer: It builds equipment maintenance history and enables tracking of total maintenance costs per asset
Linking work orders to equipment records builds a comprehensive maintenance history for each asset, enabling cost tracking, failure analysis, and informed life cycle management decisions.
