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.

Question 2

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

Accepted Answer

Percentage of planned versus reactive maintenance work

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

Accepted 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.

Question 5

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