12-2: Expected, Standard, and Actual Labor Hours
The Pizza Company makes two types of frozen pizzas: pepperoni and cheese. The Pizza
Company allocates overhead to these two products based on the number of direct labor hours. The
direct labor hours per unit for making a pepperoni pizza is 5 minutes or 1/12 of an hour. The direct
labor hours per unit for making a cheese pizza is 4 minutes or 1/15 of an hour. At the start of the
year the Pizza Company expected to make 12,000 pepperoni pizzas and 6,000 cheese pizzas.
During the year, the Pizza Company actually made 9,000 pepperoni pizzas and 7,500 cheese
pizzas. The time cards indicate that direct laborers worked for 1,300 hours. What are the total
expected direct labor hours, standard direct labor hours, and actual direct labor hours?

12-3: Establishing a Standard Cost System
The Tippa Canoe Company makes fiberglass canoes. The fiberglass resin is initially
molded to the shape of a canoe, then sanded and painted. Metal or wooden seats and frames are
added for stability. The Tippa Canoe Company was started several years ago in the owner’s garage.
The owner, Jeff George, did a lot of the initial manual labor with the help of a few friends. The
company has since expanded into a large warehouse and new employees have been hired. Because
of the expansion, Jeff is no longer directly involved with production and is concerned about his
ability to plan for and control the company. He is considering the implementation of a standard
cost system.
Required:
a. Describe the procedures Jeff should use in setting standards for direct labor and direct
materials.
b. Describe how Jeff could use standards for planning purposes,
c. Describe how Jeff could use standards for motivating employees and problems in using
standards as performance measures.
d. Why are some of Jeff’s friends who worked with from the beginning not very excited about
a change to a standard cost system?

12-4: Materials Quantity Variance: Solving for Actual Quantity
Todco planned to produce 3,000 units of its single product, Teragram, during November.
The standard specifications for one unit of Teragram include six pounds of material at $0.30 per
pound. Actual production in November was 3,100 units of Teragram. The accountant computed
a favorable materials purchase price variance of $380 and an unfavorable materials quantity
variance of $120.
Required:
Based on these data, calculate how many pounds of material were used in the production
of Teragram during November.

Hospital Software sells and installs computer software used by hospitals for patient
admissions and billing. Every sale requires that Hospital Services modify its proprietary software
for the specific demands of the client. Prior to each installation, Hospital Software estimates the
number of hours of programming time each job will require and the cost of the programmers.
Programmers record the amount of time they spend on each modification, and variance reports are
prepared at the end of each installation.
For the Denver General Hospital account, Hospital Software estimates the following labor
standards:
Standard

Senior programmer (36 hours)
$1,044
Required:
Calculate the labor efficiency and labor wage rate variances for the junior and senior
programmers on the Denver General Hospital account.

Associated Media Graphics (AMG) is a rapidly expanding company involved in the mass
reproduction of instructional materials. AMG is organized into a number of production
departments, each of which is responsible for a particular stage of the production process, such as
copyediting, typesetting, printing, and binding. An engineering department provides technical
assistance to the various production units. Ralph Davis, owner and manager of AMG, has made a
concentrated effort to provide a quality product at a competitive price with delivery on the
promised due date. Expanding sales have been attributed to this philosophy. Davis is finding it
increasingly difficult to personally supervise the operations of AMG and is beginning to institute
an organizational structure that would facilitate management control.
One change recently made was the designation of operating departments as cost centers,
with control over departmental operations transferred from Davis to each departmental manager.
However, quality control still reports directly to Davis, as do the finance and accounting functions.
A materials manager was hired to purchase all raw materials and to oversee the inventory handling
(receiving, storage, etc.) and record-keeping functions. The materials manager is also responsible
for maintaining an adequate inventory based upon planned production levels.
The loss of personal control over the operations of AMG caused Davis to look for a method
of efficiently evaluating performance. Dave Cress, a new cost accountant, proposed the use of a
standard cost system. Variances for materials and labor could then be calculated and reported
directly to Davis.
Required:
a. Assume that AMG is going to implement a standard cost system and establish standards
for materials, labor, and manufacturing overhead. For each of these cost components,
identify and discuss.
(i) Who should be involved in setting the standards.
(ii) The factors that should be considered in establishing the standards.
b. Describe the basis for assignment of responsibility under a standard cost system.

12-8: Differences Between Lean Manufacturing and Standard Costing
Lean Manufacturing and standard cost accounting systems are not necessarily substitutes.
However, very few firms use both lean manufacturing and standard costs. In fact, some
management consultants who advocate lean manufacturing argue that firms should abandon their
standard cost systems.
Required:
a. Concisely describe lean manufacturing .
b. Concisely describe standard costing.
c. Why do so few firms use both lean manufacturing and standard costing together?

12-9: Developing Standards
ColdKing Company is a small producer of fruit-flavored frozen desserts. For many years,
ColdKing’s products have had strong regional sales on the basis of brand recognition; however,
other companies have begun marketing similar products in the area, and price competition has
become increasingly important. John Wakefield, the company’s controller, is planning to
implement a standard cost system for ColdKing and has gathered considerable information from
his co-workers on production and materials requirements for ColdKing’s products. Wakefield
believes that the use of standard costing will allow ColdKing to improve cost control and make
better pricing decisions.
ColdKing’s most popular product is raspberry sherbet. The sherbet is produced in 10-
gallon batches, and each batch requires six quarts of good raspberries. The fresh raspberries are
sorted by hand before entering the production process. Because of imperfections in the raspberries
and normal spoilage, one quart of berries is discarded for every four quarts of acceptable berries.
Three minutes is the standard direct labor time for sorting to obtain one quart of acceptable
raspberries. The acceptable raspberries are then blended with the other ingredients; blending
requires 12 minutes of direct labor time per batch. After blending, the sherbet is packaged in quart
containers. Wakefield has gathered the following pricing information:
• ColdKing purchases raspberries at a cost of $0.80 per quart. All other ingredients
cost a total of $4.50 per 10-gallon batch.
• Direct labor is paid at the rate of $9.00 per hour.
• The total cost of material and labor required to package the sherbet is $0.38 per
quart.
Required:
a. Develop the standard cost for the direct cost components of a 10-gallon batch of raspberry
sherbet. For each direct cost component of a batch of raspberry sherbet, the standard cost
should identify the
(i) standard quantity.
(ii) standard rate.
(iii) standard cost per batch.
b. As part of the implementation of a standard cost system at ColdKing, John Wakefield plans
to train those responsible for maintaining the standards in the use of variance analysis.
Wakefield is particularly concerned with the causes of unfavorable variances.
(i) Discuss the possible causes of unfavorable materials price variances and identify
the individual(s) who should be held responsible for them.
(ii) Discuss the possible causes of unfavorable labor efficiency variances and identify
the individual(s) who should be held responsible for them.
