In ’09, we launched an extensive retraining program
for our order entry department and reassigned duties.
External vs. internal errors
External (customer) errors waste your time and money to
correct and may jeopardize your relations with end user
customers, so we spend lots of effort in stopping them.
Internal errors make us less productive, which increases
our costs. They also jeopardize employee harmony and
satisfaction. So, we want to get rid of them, too. Example
of an internal error: an order entry error made by our
customer service people, which our shipping department
catches and corrects before you see it.
