Table

shows the relation between goals and sub-goals. X represents the depen-
dency between a goal and a sub-goal in the sense that at least one person who
selected the goal in the row also selects the sub-goal. For example, the goal A,
“Better Service Quality”, is associated to three sub-goals; (7) “Avoiding the Contact
to Staffs”, (9) “No-Hurry at the Self-Checkout System”, and (13) “Avoid the Claims
on Handling Goods”.
