The fishbone diagram identifies incorrect stand measurements as the root cause of delayed delivery of water tanks to customers. This occurred when stands were provided with incorrect measurements, which resulted in tanks not fitting onto the stands. Key issues included employees not double checking stand measurements before transfer, stands being transferred with the wrong measurements, and inaccurate or outdated stand measurement lists being provided. The consequences were tanks being put on hold, additional rework of stands, and delayed inspection and delivery of tanks to customers.

Conclusion/Comments:
Delayed delivery of
water tanks due to
stand provided with
incorrect measurements
1. Correct measurements of stands needed should be followed at all times to avoid delayed schedule of tank release.
2. List of stand measurments must be accurate, updated and be provided to all involved employees.
