Wrench time is the share of a technician's paid time spent actually doing hands-on maintenance work.
Estimate how much of your technicians' day is actual hands-on-tools work versus travel, waiting, and admin. No work sampling study required — just honest answers about how time gets spent.
The portion of paid time spent with hands on tools, versus traveling, waiting, and finding parts.
Properly, it requires work sampling. Maximo shows the contributing factors like kitting, staging, and planning quality, not wrench time directly.
Many organizations land around 25 to 35 percent. Well-run programs reach the 50s.
Attack the wait: kitting, staging, planning, and tool availability, not pushing technicians to move faster.
