Perfection versus Practical
Standards: A Behavioral Issue
Should we use
practical standards
or perfection
standards?
Practical standards
should be set at levels
that are currently
attainable with
reasonable and
efficient effort.
9. 10-9
I agree. Perfection
standards are
unattainable and
therefore discouraging
to most employees.

Use of Standards by
Service Organizations
• Standard cost
analysis may be used
in any organization
with repetitive tasks.
• A relationship
between tasks and
output measures
must be established.

Actual Price Standard Price Standard Price
Price Variance Quantity Variance

AQ(AP - SP) SP(AQ - SQ)
AQ = Actual Quantity SP = Standard Price
AP = Actual Price SQ = Standard Quantity

Significance of Cost Variances
What clues help me
to determine the
variances that I should
investigate?

If I buy cheaper materials, my direct-
materials expenses will be lower than
what is budgeted. Then I’ll get my bonus.
But we may lose customers because of
lower quality.

Costing
15. 10-15
Interaction among Variances
I am not responsible for
the unfavorable labor
efficiency variance!
You purchased cheap
material, so it took more
time to process it.
You used too much
time because of poorly
trained workers and
poor supervision.

Standard Costs and Product
Costing
Standard material and labor costs
are entered into Work-in-Process
inventory instead of actual costs.
Standard cost variances
are closed directly to
Cost of Goods Sold.
