MMC Maintenance Planning & Scheduling 3 — Questions and Answers
Question 1: What is the typical recommended 'ready backlog' for a maintenance crew expressed in weeks of work?
- Less than 1 week
- 2 to 4 weeks (Correct answer)
- 8 to 12 weeks
- More than 6 months
Correct answer: 2 to 4 weeks
A ready backlog of 2–4 weeks provides schedulers enough flexibility to assign work efficiently without letting the queue grow unmanageable.
Question 2: In a maintenance planning context, what does 'kitting' refer to?
- Organizing technicians into specialized skill groups
- Pre-staging all required parts and materials for a job before it begins (Correct answer)
- Reviewing equipment manuals for a new asset
- Installing spare parts in a central storage location
Correct answer: Pre-staging all required parts and materials for a job before it begins
Kitting means gathering and pre-staging all parts, tools, and materials for a job so the technician has everything ready when work starts.
Question 3: Which document provides the detailed step-by-step instructions a planner writes for a specific maintenance job?
- Equipment specification sheet
- Job plan or work package (Correct answer)
- Maintenance strategy document
- Capital expenditure request
Correct answer: Job plan or work package
A job plan or work package includes step-by-step procedures, required parts, tools, safety precautions, and estimated labor hours for a specific task.
Question 4: What role does the 'scheduler' play that is DISTINCT from the 'planner' in a maintenance organization?
- Writing detailed job procedures and estimating craft hours
- Assigning planned work to specific crews and time slots (Correct answer)
- Ordering spare parts and managing inventory
- Approving capital expenditure for major repairs
Correct answer: Assigning planned work to specific crews and time slots
The scheduler's distinct role is to assign planned work orders to specific crews and time periods, balancing availability and priorities.
Question 5: How does 'constraint identification' improve maintenance scheduling?
- It limits the number of work orders a planner can process per day
- It identifies parts, permits, or equipment shutdowns needed so schedule conflicts are avoided (Correct answer)
- It restricts overtime spending by capping daily labor hours
- It ensures all work orders are approved by engineering before scheduling
Correct answer: It identifies parts, permits, or equipment shutdowns needed so schedule conflicts are avoided
Identifying constraints—such as missing parts, required permits, or equipment lockout windows—prevents scheduling jobs that cannot actually be executed as planned.
Question 6: What is the primary benefit of integrating maintenance scheduling with production planning?
- Reducing the number of maintenance technicians required
- Aligning planned downtime windows with production schedules to minimize output loss (Correct answer)
- Eliminating the need for emergency work orders
- Allowing maintenance to set its own budget independently
Correct answer: Aligning planned downtime windows with production schedules to minimize output loss
Coordinating maintenance windows with production plans minimizes unplanned disruptions and maximizes equipment availability during peak production periods.
Question 7: Which of the following is considered a 'leading indicator' in maintenance planning performance?
- Mean time between failures (MTBF)
- Percentage of work orders that are planned before execution (Correct answer)
- Total maintenance cost per year
- Number of equipment breakdowns last quarter
Correct answer: Percentage of work orders that are planned before execution
The percentage of work orders planned before execution is a leading indicator because it predicts future performance improvements, unlike lagging metrics that report past events.
