Maintenance Planning and Scheduling Flashcards

What is the primary goal of maintenance planning in a reliability-centered organization?

Answer: Ensure all necessary resources and information are available before work begins

Effective maintenance planning ensures that labor, parts, tools, permits, and instructions are all in place before a job starts, eliminating delays and improving wrench time.

Which metric best measures the effectiveness of a maintenance planning function?

Answer: Percentage of planned versus reactive maintenance work

The ratio of planned (proactive) to reactive (unplanned) maintenance work directly reflects how well the planning function is preventing emergency breakdowns.

In maintenance scheduling, what does 'schedule compliance' measure?

Answer: The percentage of work orders completed within the scheduled time window

Schedule compliance measures the percentage of scheduled work orders that were actually completed as planned, indicating adherence to the maintenance schedule.

What is 'wrench time' in the context of maintenance management?

Answer: The percentage of a technician's shift spent performing actual hands-on maintenance work

Wrench time is the proportion of a technician's total available time spent actually performing productive maintenance tasks, typically 25–35% in unplanned environments and 50–55% in well-planned ones.

A maintenance planner is developing a job plan for an equipment overhaul. Which element is MOST critical to include?

Answer: Detailed task steps, required parts, special tools, and estimated labor hours

A complete job plan must contain task sequences, required materials, special tools and permits, and labor estimates so that all resources are mobilized before work begins.

What is the recommended sequence for processing a maintenance work order from initiation to closure?

Answer: Identify → Plan → Schedule → Execute → Close/Document

The standard work order process flows from identification and prioritization, through planning and scheduling, to execution and documentation, ensuring accountability and continuous improvement.

Which of the following best describes a 'backlog' in maintenance management?

Answer: Approved, planned work that has not yet been scheduled or executed

The maintenance backlog is the accumulation of approved and planned work orders awaiting scheduling and execution, and managing it is essential to balancing workload and resources.
