The improper use of standard costs can present a number of
potential problems that are as follows:
- Standard cost variance reports are usually prepared on a
monthly basis and often are released days or even weeks after the
end of the month. As a consequence,the information in the reports
may be so outdated that it is almost useless.
- If managers are insensitive and use variance reports as a club,
morale will suffer. Management by exception tends to focus on the
negative. If variances are used as a club, subordinates may be
tempted to cover up unfavorable variances or take actions that are
not in the best interests of the company to make sure the variances
are favorable.
- Labor quantity standards and efficiency variances assume that
production is labor-paced. However, output in many companies is
determined by the processing speed of machines. Second, the
computations assume that labor is a variable cost. Direct labor may
be essentially fixed. If labor is fixed, then an undue emphasis on
labor efficiency variances creates pressure to build excess
inventories.
- Sometimes a “favorable” variance can be as bad or worse than an
“unfavorable” variance. Favorable variances can lead to substandard
products and dissatisfied customers.
- Too much emphasis on meeting the standards may overshadow other
important objectives.
- Just meeting standards may not be sufficient; continual
improvement may be necessary to survive in a competitive
environment.
