Which planning principle states that planners should use feedback from completed jobs to improve future job plans?
Answer: Continuous improvement through planner feedback loops
Planners should review technician feedback and actual vs. estimated hours after job completion to refine job plans and improve future accuracy.
What is the purpose of a 'maintenance strategy' document for an asset class?
Answer: To define which maintenance tasks, frequencies, and methods apply to a given type of equipment
A maintenance strategy specifies the appropriate mix of preventive, predictive, and corrective tasks and their frequencies for a given asset class.
In the context of planning and scheduling, what is a 'work order priority matrix' used for?
Answer: Consistently classifying work orders by urgency and business impact to guide scheduling decisions
A priority matrix provides a structured, consistent method for assigning priority levels to work orders based on safety risk, production impact, and regulatory requirements.
What distinguishes 'proactive maintenance' from 'reactive maintenance' from a planning perspective?
Answer: Proactive maintenance is planned and executed before failure occurs; reactive addresses failures after they happen
Proactive maintenance anticipates and prevents failures through scheduled tasks, while reactive maintenance responds to failures that have already disrupted operations.
How does 'staging' parts and tools before a job contributes to maintenance efficiency?
Answer: It eliminates time technicians would otherwise spend searching for and retrieving materials during the job
Pre-staging parts and tools eliminates non-productive time spent retrieving materials, directly increasing wrench time and job efficiency.
Which scheduling approach involves identifying the longest chain of dependent tasks to determine a project's minimum completion time?
Answer: Critical path method (CPM)
The critical path method identifies the sequence of dependent tasks with the longest total duration, defining the minimum time needed to complete a maintenance project.
What is the significance of 'planner-to-technician ratio' as a benchmark in maintenance organizations?
Answer: It indicates whether the planning function is adequately staffed to support the craft workforce
The planner-to-technician ratio (commonly benchmarked at 1:15 to 1:30) indicates whether planning capacity is sufficient to keep ahead of the craft workforce's needs.
