Standard cost
Extracted from the Wikipedia article Standard cost accounting.
Overview
Standard cost accounting uses ratios called efficiencies that compare the labor and materials actually used to produce a good with those that the same goods would have required under "standard" conditions. As long as actual and standard conditions are similar, few problems arise. Unfortunately, standard cost accounting methods developed about 100 years ago, when labor comprised the most important cost of manufactured goods. Standard methods continue to emphasize labor efficiency even though that resource now constitutes a (very) small part of the cost in most cases.
