A container in repair is unavailable to the fleet. Record when it enters repair and when it is usable again; open job count alone does not show capacity tied up.
The calculation
Count each container's repair days over defined dates and sum them. Report container-days with the calendar period used.
Where the waiting happens
Parts wait: the job is open but work has not started.
Queue wait: the team has not started the work.
Decision wait: authorization for repair or another action is pending.
Closure wait: work is done but the container has not returned to inventory or the record remains open.
Why separate the four
Count reasons separately: parts, scheduling, decisions and records may have different owners. Define categories to match the site's workflow.
Link to spare container count
Divide the total by fleet size for a period-level per-container measure. It compares capacity tied up; it does not set spare purchasing by itself.
Monthly follow-up
Report repairs opened, closed and container-days each month. Since jobs can open and close in different months, these counts are not a simple balance.
