CAFM Maintenance Management Questions and Answers — Questions and Answers
Question 1: A fleet manager is implementing a predictive maintenance (PdM) program. Unlike a traditional preventive maintenance (PM) program, what is the primary trigger for scheduling a maintenance intervention in a PdM strategy?
- The vehicle reaching a predetermined mileage interval.
- Real-time data from onboard sensors indicating a potential component failure. (Correct answer)
- The manufacturer's recommended service schedule.
- A fixed time-based interval, such as every six months.
Correct answer: Real-time data from onboard sensors indicating a potential component failure.
Predictive maintenance (PdM) uses real-time data from sensors and analytics to monitor the actual condition of equipment to predict when maintenance should be performed. This contrasts with preventive maintenance (PM), which is based on predetermined schedules, such as time, mileage, or engine hours.
Question 2: A fleet's in-house maintenance shop is struggling with vehicle downtime due to technicians waiting for parts. To improve efficiency, the manager implements an inventory management system where parts are categorized based on their usage value (high-value, fast-moving vs. low-value, slow-moving). Which inventory control method is being described?
- Just-in-Time (JIT) Inventory
- First-In, First-Out (FIFO)
- ABC Analysis (Correct answer)
- Economic Order Quantity (EOQ)
Correct answer: ABC Analysis
ABC analysis is a widely used inventory categorization method that divides items into three categories—A, B, and C—based on their consumption value. 'A' items are the most valuable (high usage value), 'C' items are the least valuable, and 'B' items are in between. This allows managers to focus control efforts on the most significant items.
Question 3: When managing a warranty recovery program, which of the following is a critical practice for ensuring successful claims?
- Discarding failed parts immediately to keep the shop clean.
- Relying solely on verbal agreements with the service provider.
- Waiting until the end of the fiscal year to submit all claims in a batch.
- Properly tagging and retaining failed components for potential manufacturer inspection. (Correct answer)
Correct answer: Properly tagging and retaining failed components for potential manufacturer inspection.
Manufacturers often require the inspection of failed parts to approve a warranty claim. A best practice is to have a designated parts retention program where failed components are tagged with relevant information (vehicle number, date, mileage) and held for a specific period (e.g., 45-60 days) in case the manufacturer requests them for evaluation.
Question 4: A fleet manager decides to outsource all maintenance and repair services for a fleet of highly specialized vehicles. Which of the following is a primary advantage of this strategy?
- Increased direct control over repair prioritization and scheduling.
- Lower per-hour labor rates compared to in-house technicians.
- Access to specialized technicians and diagnostic equipment without high capital investment. (Correct answer)
- Reduced need for communication and relationship management with external vendors.
Correct answer: Access to specialized technicians and diagnostic equipment without high capital investment.
Outsourcing provides access to technicians with specialized skills and state-of-the-art equipment, which can be prohibitively expensive to maintain in-house, especially for complex or specialized vehicles. This allows the fleet to receive expert service without the associated overhead costs of training and tool acquisition.
Question 5: A key performance indicator (KPI) for a maintenance shop is 'Technician Productivity.' How is this metric typically calculated?
- The total number of work orders completed divided by the number of technicians.
- The total hours a technician is clocked in, minus breaks and meetings.
- The ratio of hours spent on direct, revenue-generating repair work to the total hours paid. (Correct answer)
- The percentage of repairs that need to be redone within a 30-day period.
Correct answer: The ratio of hours spent on direct, revenue-generating repair work to the total hours paid.
Technician productivity, sometimes referred to as 'wrench time,' measures the percentage of a technician's paid time that is spent directly working on a vehicle ('turning wrenches'). It separates productive, hands-on time from indirect time like cleaning, training, or waiting for parts. An industry ideal is often around 70%.
Question 6: Which of the following maintenance strategies is considered proactive rather than reactive?
- Demand Maintenance
- Crisis Maintenance
- Breakdown Maintenance
- Preventive Maintenance (Correct answer)
Correct answer: Preventive Maintenance
Preventive maintenance is a proactive strategy that involves performing regularly scheduled maintenance tasks on vehicles to lessen the likelihood of them failing. This contrasts with reactive strategies like breakdown or crisis maintenance, which only address problems after a failure has already occurred.
