24 STANDARD COST SYSTEMS
Chapter Summary
The analysis of standard cost systems begins with the development of standards
for direct materials, direct labor, and manufacturing overhead. These discussions
emphasize that standards are set in accordance with normal and not ideal operating
conditions. This includes setting overhead standards consistent with normal production
volume.
An extended illustration introduces all variance calculations. The variances
isolated include price and quantity variances for direct material and labor, the spending
variance for overhead, and the volume variance. Each variance calculation is shown in
the form of an equation using the familiar three-benchmark diagram. The discussion of
direct material does not distinguish between quantities purchased and used. Thus, the
price and quantity variances are calculated using the same standard quantity. The
treatment of overhead variances follows the "two-way" format. Note, however, that the
illustration contains sufficient detail for those who wish to employ a "three-way" or "four-
way" analysis.
Journal entries are introduced to record standard costs in the work-in-process
inventory account, and to record the variances in appropriate accounts. End-of-period
closing entries to dispose of the variance balances are not discussed in detail.
To close discussion of our illustration, the variances are evaluated from the
perspectives of a number of different managers.

Comments and observations
Teaching objectives for Chapter 24
1 Explain the basic purpose of a standard cost system.
2 Distinguish between ideal and normal standards and explain the significance of
this distinction to the process of developing standard costs.
3 For each of the six cost variances described in the chapter:
a Explain the nature of the variance
b Discuss possible causes and the manager most likely responsible
c Review the computation of the variance
d Illustrate the journal entry to record the variance and related standard cost
4 Discuss the merits of valuing inventory and the cost of goods sold at standard cost,
with cost variances shown separately, compared with valuing inventory and the cost
of goods sold at actual cost.
5 Describe the year-end disposition of the balances in the variance accounts.
6 Discuss the inherent limitations of a standard cost system.
General comments
Cost control is critical to the competitive position of a business and has thus received
considerable attention in the academic and professional literature. Despite the growing
popularity of just-in-time approaches to the management of costs, we believe traditional
standard cost systems and control via cost variances to be relevant and of vital
importance.
It is important to establish the nature of a standard cost system at the outset. Students
have difficulty appreciating that standard costing is not an alternative to job-order or
process systems, but a variant of those systems. We always spend class time
distinguishing among actual, normal, and standard costs in both job-order and process
environments. Discussion Question 2 and Problem 4, which applies standard costs in a
process system, are helpful in this regard.
In covering standard costs, we find that some students fail to associate standard costs
with the flow of manufacturing costs through a cost accounting system. Rather, they
view the computation of cost variances as calculations made independently of the
recording function. Problems 3 through 8 and Case 2 are designed to show that standard
costs are indeed an integral part of the cost accounting system. To reinforce this point,
you may wish to call to students' attention the fact that the use of standard costs in a
process cost system eliminates the need for tedious calculations of cost per equivalent
unit, since standard cost is the cost per equivalent unit. Again, Problem 4 makes this
point nicely.
In covering standard costs it is crucial not to focus solely upon mechanics.
Whenever we compute a variance, we believe that it is important to discuss the nature
Chapter 24 - Standard Cost Systems
and the probable cause of that variance. Exercises 5 and 6 and Case 1 are all designed
to focus upon the interpretation of cost variance information. Finally, we recommend an
in-class review of Exercise 7. On the surface, this exercise appears quite mechanical.
Actually, it is both conceptual and comprehensive in nature. Students able to explain
their answers to this exercise have acquired a thorough understanding of "cost variances."
We view standard cost systems as an essential component of responsibility
accounting systems and as an extension of flexible budgeting.
Supplemental Exercises
Group Exercise
As a group read and solve Problem 6 in your text. Organize a role play for the class
to illustrate your interpretation of the variance information in the problem. One member
of the group should act as company controller or cost accountant and present the variance
results to a meeting of managers played by members of the group. Group members
should take on the roles of purchasing manager, production superintendent, marketing
manager and, employee grievance representative. Each "manager" should interpret the
control significance of the variances he or she is responsible for and explain the
corrective actions, if any, planned.
Internet Exercise
Search the web for an article dealing with the topics of cost control or standard cost
variance analysis. Obtain a copy of the article and write a brief report summarizing its
major points.
