Perfection versus Practical Perfection versus Practical Standards: A Behavioral IssueStandards: A Behavioral Issue
Should we usepractical standards
or perfection standards?
Practical standardsshould be set at levels
that are currentlyattainable with reasonable andefficient effort.
10-6
I agree. Perfection standards are
unattainable and therefore discouraging
to most employees.

Let’s use the concepts
of the general model to
calculate standard cost
variances, starting with
direct material.

Material VariancesMaterial Variances
Hanson Inc. has the following direct material standard to manufacture one Zippy:
1.5 pounds per Zippy at $4.00 per pound
Last week 1,700 pounds of material were purchased and used to make 1,000 Zippies. The
material cost a total of $6,630.

Quantity variance$800 unfavorable
Material Variances SummaryMaterial Variances Summary
10-14
The price variance is computed on the entire
quantity purchased.
The quantity variance is computed only on the
quantity used.
Hanson purchased and used 1,700 pounds.
How are the variances computed if the amount purchased differs from
the amount used?

Hanson Inc. has the following material standard to manufacture one Zippy:
1.5 pounds per Zippy at $4.00 per pound
Last week 2,800 pounds of material were purchased at a total cost of $10,920, and 1,700
pounds were used to make 1,000 Zippies.

$10,920 $11,200
Price variance$280 favorable
Price variance increases because quantity
purchased increases.
Zippy
MPV = AQ(AP - SP)MPV = 2,800 lbs. × ($3.90 - 4.00)MPV = $280 Favorable

Actual Quantity Used Standard Quantity × × Standard Price Standard Price
1,700 lbs. 1,500 lbs. × × $4.00 per lb. $4.00 per lb.
$6,800 $6,000
Quantity variance$800 unfavorable
Quantity variance is unchanged because actual and standard
quantities are unchanged.

MQV = SP(AQ - SQ) MQV = $4.00(1,700 lbs
- 1,500 lbs) MQV = $800 unfavor.

Isolation of Material VariancesIsolation of Material VariancesI need the variances as soon
as possible so that I canbetter identify problems
and control costs.
You accountants just don’tunderstand the problems
we production managers have.
Okay. I’ll start computingthe price variance when
material is purchased andthe quantity variance assoon as material is used.

Now let’s calculate standard cost variances for direct labor.
10-20
Hanson Inc. has the following direct labor standard to manufacture one Zippy:
1.5 standard hours per Zippy at $10.00 per direct labor hour
Last week 1,550 direct labor hours were worked at a total labor cost of $15,810 to
make 1,000 Zippies.

Significance of Cost VariancesSignificance of Cost Variances
1. Size of variance1. Dollar amount2. Percentage of
standard
2. Recurring variances3. Trends4. Controllability5. Favorable variances6. Costs and benefits
of investigation
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.

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