Situation: when they ship out tires from their warehouses, they have shipping discrepancies such

as tire shortage, tire overage, and tire damage. A lot of non$-$value$-$added work is needed to

Observations: through brainstorming sessions, they have found possible main causes and root

causes of the process. They collected the data and illustrated frequencies of each possible root

cause as shown in the table below.
