Accuracy
Total accuracy averages 99.75% in ’07!
- External errors increase 36%
- Internal errors increase 33%
Why the increase?
- A kaizen in April ’07 uncovered a cumbersome corrective/preventive action system that employees weren’t using all the time. We redesigned and installed a new, simpler online system.
- So, error tracking in prior years hadn’t been completely accurate. But, that’s what continuous improvement is all about; never being satisfied with your results.
- External vs. internal errors
- External errors waste your time and money to correct and may jeopardize your relations with customers, so we spend lots of effort in stopping them.
- Internal errors make us less productive, which increases our costs. They also harm employee harmony and satisfaction. So, we want to get rid of them, too. A mistake such as order entry error, which our shipping department catches, is an internal error.
