Read one by one, every repair record is a completed job. Sort the same records by container number and something else shows: on some containers the same part is written up again every few months. That similarity points to where to investigate; it does not prove a cause.
Making the repeat visible
Each record carries container ID, part, fault type and closure date. Set the follow-up period in advance and count how often the same container-part pair returns within it. For example, if 12 of a hypothetical 80 repairs recur on the same container and part within 90 days, the repeat rate is 12/80, or 15%.
Once a pair appears several times in a short span, it is no longer separate faults but a pattern. Replacing the same part once more leaves the question of why the earlier ones did not hold unanswered. A repeat can persist for these reasons:
- The part may have been fitted wrongly, leaving the first repair incomplete.
- Whatever damages the part may still be there: forklift contact, a narrow door, rough ground.
- The container may be working the wrong line, with a load or handling that does not suit it.
- A temporary repair may have been taken as permanent: the record closed, the problem did not.
When to close the record
A record closes after the container has been tried; fitting the part is not enough. State the work, the trial and the return time in the closing note; if no trial was possible, record that and keep the follow-up open. Label the temporary action and the planned next check clearly, because a repair not written as temporary is taken for permanent months later and nobody looks there while hunting the cause of a recurring fault.
Review the repeating pair by container, part, date and use context. If the same part shows across many containers, the question changes: is it the part, the use or the spare being fitted? Then compare part batch, sourcing and fitting records, since examining containers one by one gets nowhere here.
