The $1,229 favorable direct materials cost variance indicates that Root’s managers did a good job
keeping actual direct materials cost per yard within standard. The $8.50 actual cost per yard was less
than the $8.70 standard cost per yard.
The $8,600 unfavorable variable overhead cost variance indicates that Root’s managers did not do a
good job keeping actual variable overhead cost per yard within standard. The $6.40 actual cost per yard
was greater than the $5.00 standard cost per yard (the standard variable overhead allocation rate per
yard).
The $2,000 unfavorable fixed overhead cost variance indicates that Root’s managers did not do a good

This continues the Daniels Consulting situation from Problem P22-57 of Chapter 22. Assume Daniels
has created a standard cost card for each job. Standard direct materials per job include 10 software
packages at a cost of $900 per package. Standard direct labor costs per job include 105 hours at $100 per
hour. Daniels plans on completing 12 jobs during March 2018.
Actual direct materials costs for March included 90 software packages at a total cost of $81,450. Actual
direct labor costs included 110 hours per job at an average rate of $107 per hour. Daniels completed all
12 jobs in March.
Requirements
1. Calculate direct materials cost and efficiency variances.

Decision Case 23-1
Suppose you manage the local Scoopy’s ice cream parlor. In addition to selling ice cream cones, you
make large batches of a few flavors of milk shakes to sell throughout the day. Your parlor is chosen to
test the company’s “Made-for-You” system. This new system enables patrons to customize their milk
shakes by choosing different flavors.
Customers like the new system and your staff appears to be adapting, but you wonder whether this
new made-to-order system is as efficient as the old system in which you just made a few large batches.
Efficiency is a special concern because your performance is evaluated in part on the restaurant’s
efficient use of materials and labor. Your superiors consider efficiency variances greater than 5% to be
unacceptable.
You decide to look at your sales for a typical day. You find that the parlor used 390 pounds of ice
cream and 72 hours of direct labor to produce and sell 2,000 shakes. The standard quantity allowed for a
shake is 0.2 pound of ice cream and 0.03 hour of direct labor. The standard costs are $1.50 per pound for
ice cream and $8 per hour for labor.
Requirements
1. Compute the efficiency variances for direct labor and direct materials.
2. Provide likely explanations for the variances. Do you have reason to be concerned about your
performance evaluation? Explain.
3. Write a memo to Scoopy’s national office explaining your concern and suggesting a remedy.

Requirement 2
The $15 favorable direct materials efficiency variance indicates that actual usage of direct materials (ice
cream) was kept within standard. The 390 pounds of ice cream actually used was less than the 400
pounds allowed to produce 2,000 shakes. Although favorable, the variance is relatively small—only
2.5% under the $600 total direct materials standard allowed to produce 2,000 shakes(a).

SUBJECT: “Made-for-You” System
The “Made-for-You” system test has yielded some benefits. Customers enjoy being able to customize
their shakes, employees appear to be adapting, and the direct materials efficiency variance is favorable.
However, employees are relatively less efficient under the new system. The unfavorable direct labor
efficiency variance is 20% over the current direct labor standard allowed for actual shakes produced.
Fraud Case 23–1
Drew Castello, general manager of Sunflower Manufacturing, was frustrated. He wanted the budgeted
results, and his staff was not getting them to him fast enough. Drew decided to pay a visit to the
accounting office, where Jeff Hollingsworth was supposed to be working on the reports. Jeff had
recently been hired to update the accounting system and speed up the reporting process.
After looking at the time records, Jeff pointed out that it was unusual that every employee in the
production area recorded exactly eight hours each day in direct labor. Did they not take breaks? Was no
one ever five minutes late getting back from lunch? What about clean-up time between jobs or at the end
of the day?
Drew began to observe the production laborers and noticed several disturbing items. One employee
was routinely late for work, but his time card always showed him clocked in on time. Another employee
took 10- to 15-minute breaks every hour, averaging about 1½ hours each day, but still reported eight
hours of direct labor each day. Yet another employee often took an extra 30 minutes for lunch, but his
time card showed him clocked in on time. No one in the production area ever reported any “down time”
when they were not working on a specific job, even though they all took breaks and completed other
tasks such as doing clean-up and attending department meetings.
Requirements
1. How might the observed behaviors cause an unfavorable direct labor efficiency variance?
2. How might an employee’s time card show the employee on the job and working when the employee
was not present?
3. Why would the employees’ activities be considered fraudulent?

The direct labor efficiency variance measures actual labor usage compared to standard labor usage. If

Team Project 23-1
Lynx Corp. manufactures windows and doors. Lynx has been using a standard cost system that bases
cost and efficiency standards on Lynx’s historical long-run average performance. Suppose Lynx’s
controller has engaged your team of management consultants to advise him or her whether Lynx should
use some basis other than historical performance for setting standards.
Requirements
1. List the types of variances you recommend that Lynx compute (for example, direct materials cost
variance for glass). For each variance, what specific standards would Lynx need to develop? In
addition to cost standards, do you recommend that Lynx develop any nonfinancial standards?
2. There are many approaches to setting standards other than simply using long-run average historical
costs and quantities.
a. List three alternative approaches that Lynx could use to set standards, and explain how Lynx
could implement each alternative.
b. Evaluate each alternative method of setting standards, including the pros and cons of each
method.
c. Write a memo to Lynx’s controller detailing your recommendations. First, should Lynx retain its
historical data-based standard cost approach? If not, which of the alternative approaches should it
adopt?

SUBJECT: Standard Costs
However, we suggest that Lynx examine trade publications for relevant benchmark data, and explore the
possibilities of partnering with other manufacturers to obtain external benchmark data. If benchmark
data are too costly or impossible to obtain, then we recommend conducting time-and-motion studies in
order to set tight, but achievable, standards. In future years, these standards could form the baseline for
continuous improvement adjustments that would give employees incentives to increase efficiency.
