Common Errors in Measuring System Performance
When a warehouse manager suspects poor system performance, the first step is typically to check the real data. Unfortunately, more than 50% of the time, system performance is measured incorrectly. Data is only as good as the methods used to calculate it; if something is measured the wrong way, the results will be wrong. This may lead to the justification of system changes, or even an entirely new system, based on imprecise data.
