CHAPTER OVERVIEW
Chapter 11 is about the decision-making process. Accountants are an integral part of this process,
providing information to decision makers. A five-step approach to making decisions, beginning with the
point in the process in which the accountants typically become involved, is described in the chapter.
An extremely useful concept is presented. The information needed for the decision process must be
relevant to the decision. Relevant is defined as revenues and costs that occur in the future and differ
among the alternative courses of action available to the decision maker. This definition is illustrated
through various situations. In this chapter the information needed for decisions of one-time-only special
orders, make-or-buy, drop-or-add, and keep-or-replace are explained. Several of the chapters that follow
will introduce other types of decisions that use the concept of relevant revenues and costs.
A major theme of the text is that information generated by the accounting system is used for the benefit of
managers in making decisions. The roles performed by accountants are implicit in the illustrations of
relevant information gathered for decisions—problem solving, scorekeeping, and attention directing. A
review of those roles from Chapter 1 could be used to highlight their importance in the decision process.
The last step of the decision process is evaluating performance. The last section of the chapter deals with
conflicts between the decision model used by a manager and the performance model then used to evaluate
that manager. This is an important discussion.

Linear programming as a tool in the decision process is described in the appendix.

Decision Making and Relevant Information 141


CHAPTER OUTLINE
I.

Information and the decision process
A. Define the decision under consideration

TEACHING TIP: A clear understanding of the purpose of the decision is helpful in working through the
steps in the decision process. By carefully and quite specifically defining the decision to be made, the
determination of relevant costs and relevant revenues for each alternative is usually easier. Continued
emphasis on the definition of relevant cannot be overdone.

3. [CPA Adapted] Mikaelabelle Products sells product A at a selling price of $40 per unit.
Mikaelabelle’s cost per unit based on the full capacity of 500,000 units is as follows:
Direct materials
Direct labor
Indirect manufacturing (60% of which is fixed)

$ 6

10
$19

A one-time-only special order offering to buy 50,000 units was received from an overseas
distributor. The only other costs that would be incurred on this order would be $4 per unit for

shipping. Mikaelabelle has sufficient existing capacity to manufacture the additional units. In
negotiating a price for the special order, Mikaelabelle should consider that the minimum selling
price per unit should be
a. $17.

b. $19.

c. $21.

d. $23.

The following data apply to questions 4 and 5.
Troy Instruments uses ten units of Part Number S1798 each month in the production of scientific
equipment. The unit cost to manufacturing one unit of S1798 is presented below.
Direct materials
Materials handling (10% of direct materials cost)
Direct manufacturing labor
Indirect manufacturing (200% of direct labor)
Total manufacturing cost

$ 4,000
400
6,000
12,000
$22,400

Materials handling represents the direct variable costs of the Receiving Department that are applied to
direct materials and purchased components on the basis of their cost. This is a separate charge in addition
to indirect manufacturing cost. Troy’s annual indirect manufacturing cost budget is one-fourth variable
and three-fourths fixed. Duncan Supply, one of Troy’s reliable vendors, has offered to supply Part

Number S1798 at a unit price of $17,000.
4. [CMA Adapted] If Troy purchases the S1798 units from Duncan, the capacity Troy used to
manufacture these parts would be idle. Should Troy decide to purchase the parts from Duncan, the
unit cost of S1798 would
a. decrease by $3,700.

b. decrease by $5,600. c. increase by $3,600.

d. increase by $5,300.

5. [CMA Adapted] Assume that Troy Instruments does not wish to commit to a rental agreement to rent
all idle capacity but could use idle capacity to manufacture another product that would contribute
$60,000 per month. If Troy elects to manufacture S1798 in order to maintain quality control, Troy’s
opportunity cost is
a. $(53,000).

b. $7,000.

c. $(24,000).

d. $36,000.


6. Which of the following is not a correct use of the term “opportunity cost”?
a. Opportunity costs are considered period costs rather than inventoriable costs for accounting
purposes.
b. Opportunity costs must be considered by managers when making decisions

c. Opportunity cost plus the incremental future revenues and costs equal the relevant revenues and
costs of any alternative when capacity is constrained.
d. The opportunity cost of holding inventory is the income forgone by tying up money in inventory
and not investing it elsewhere.

key question RCG should ask in deciding to keep or to drop a particular customer?
a.
b.
c.
d.

Will the customer meet a specific designated gross margin percentage?
Will the customer be willing to pay a higher price to insure RCG’s profitability?
Will enough customers be found to replace any customers dropped for lack of profitability?
Will expected total corporate office costs decrease if decision is to drop the customer?

9. [CPA Adapted] At December 31, 2001, Brown Co. had a machine with an original cost of $90,000,
accumulated depreciation of $75,000, and an estimated salvage value of zero. On December 31,
2001, Brown was considering the purchase of a new machine having a five-year life, costing
$150,000, and having an estimated salvage value of $30,000 at the end of five years. In its decision
concerning the possible purchase of the machine, how much should Brown consider as sunk cost at
December 31, 2001?

decision model?
a.
b.

c.
d.

The use of different time frames: one being an annual basis, the other a period of several years.

WRITING/DISCUSSION EXERCISES
1. Use the five-step decision process to make decisions

How does a “five-step decision process” differ from the decision process illustrated for
planning and control in an earlier chapter? Do different kinds of decisions require the
use of different models? The basic model for decision making is quite similar to a “thinking model”
because decision making is thinking. The two processes mentioned are not different in approach but in
how they are described. Each thinking or decision model require the similar steps of
♦ defining or clarifying the problem to be solved or the situation about which a decision is to be made
or an objective to be achieved
♦ gathering relevant information about the problem, situation, or objective
♦ choosing from among at least two different solutions, alternatives, or approaches
♦ implementing the solution, alternative, or approach chosen
♦ evaluating the results of the action taken
♦ using feedback to improve next decision
Each decision does not require a formal process. The steps are not rules or a checklist but are descriptive
of how people process situations.

[Refer to Writing/Discussion Exercises Chapter 1, Learning Objective 3 and Chapter 9, Learning
Objective 7]
2. Differentiate relevant from irrelevant costs and revenues in decision situations

In the study of financial accounting, a primary characteristic of accounting information is
relevance. How does that fit with the concept of relevance in cost accounting? The In
the Statements of Accounting Concepts issued by the Financial Accounting Standards Board, the two
primary characteristics of accounting information are relevance and reliability. These characteristics
support the overall characteristic of decision usefulness. Accounting information, whether developed for
cost accounting or financial accounting, derives its value from improving decisions. Each of the two
primary qualities, relevance and reliability, have significance in any type of accounting. As studied in
financial accounting (FASB Statements of Accounting Concepts), relevance has three aspects: timeliness,
feedback value, and predictive value. These same aspects are incorporated in the definition of relevant in
the text—future costs or revenues that make a difference among the alternatives.

Decision Making and Relevant Information 151


3. Distinguish between quantitative and qualitative factors in decisions

Why should the accountants have to concern themselves with qualitative factors?
Numbers are neutral. Numbers are neutral but they are also symbols. Symbols represent an idea, a
thought, a concept, or some thing. Qualitative factors are the more basic factors because numbers
typically represent some quality. Ways are found to value or assign numbers to those things that were
considered quality factors, such as product quality that is now studied in cost accounting as “costs of
quality” with numbers representing aspects of product quality.
Is a basketball player worth $2,000,000 when a day-care worker is paid $22,000 per year? The numbers
are neutral but speak boldly to qualitative issues. The imperative for accountants is that they understand
what is “behind the numbers” so they know what numbers to gather and report. Understanding the
qualitative issues in any decisions will make a difference in the numbers gathered and reported. The

difference should not be due to bias but due to purpose.
4. Beware of two potential problems in relevant-cost analysis

Can costs be stereotyped? If one deals with costs such that generalizations are always used in
place of careful consideration of an individual situation, then the problem of stereotyping can occur. To
think that all fixed costs are irrelevant would be a kind of cost stereotyping. To use a unit cost across
several levels of activity without considering the relevant range might result in a generalization that could
be harmful if used in making a decision.
5. Explain the opportunity-cost concept and why it is used in decision making

Are opportunity costs like grass that is always greener on the other side of the fence?
Opportunity costs are those costs that might have been. Because they do not happen, one cannot know
opportunity costs with any certainty. The exercise of considering “what might be if . . .” can be useful to
a company. Having to consider other alternatives clarifies the action to be taken—to choose this is also to
reject that. The use of scarce resources or limited resources should always be seen in the light of
alternatives. Obviously one cannot make a decision if only one action is available—with one action
possible, there is dictate, not decision. To have to think about other possibilities and realize opportunities
as alternatives could expand the options. The opportunities are not always better, but it is better to
consider them before the decision is made.
6. Know how to choose which products to produce when there are capacity constraints

How is the concept of constraining factors or resources related to the concept of the
accounting system reflecting the underlying operations of a company? Constraining
resources are a short-run concept, but accounting works for providing information for both the short run
and the long range. If the accounting systems accurately reflect the operations of a company, the
accountant can notice trends and direct attention to them. For example, in the case of limited machinehours, the accountant can report contribution margin per machine-hour. If skilled labor is in short supply,
the accounting reports can highlight costs in terms of how they support the workers in accomplishing their
tasks. The accounting system can be designed to insure that the company gets the most out of the things
that do the most for it.

7. Discuss what managers must consider when adding or discontinuing customers and
segments

In dropping or adding customers or segments, should the way in which costs are
assigned to the cost objects be considered? Assigning costs to the cost object includes both
cost tracing and cost allocation. For decisions of adding or dropping customers or segments, one needs to
be careful of those costs that have been allocated. Allocated costs should be looked at as a total for all of
the cost objects to which they relate. If one cost object is dropped, does the total cost decrease? If
another cost object is added, does the total cost increase? Total cost to be allocated is more important
than how it is allocated in making these decisions. Traced costs can be readily noted as to their disposal
or addition.
8. Explain why the book value of equipment is irrelevant in equipment-replacement decisions

Explain the statement “All future costs are not relevant but all relevant costs are future
costs.” Book value that would be written off in the future is not a relevant cost. Book value represents
a cost that has already happened and any decision made afterwards could not change the decision that
caused the equipment to be purchased initially (except in science fiction stories).
Costs that do not affect the decision, though they are costs yet to be, are not relevant. A relevant cost
must be one that makes a difference among the alternatives.
If nothing can be done to prevent the cost from occurring, that cost is not a matter of choice—decisions
are making choices and a future cost that cannot be prevented from occurring is not relevant (must make a
difference).
One must have a choice as to whether to incur the cost or not to incur the cost for the cost to be relevant to
a decision or choice. A cost that has already been incurred is no longer in the category of to be or not to
be.

9. Explain how conflicts can arise between the decision model used by a manager and the
performance evaluation model used to evaluate the manager

Why can the conflict between the decision model used by a manager and the
performance model used to evaluate the manager be compared to a chemical change?
As stated in the text, the practical difficulty is that accounting systems rarely track each decision
separately. Individual managers are making many decisions at any given time. Hopefully the results of
the decisions weave together in such a way that the company operates “like a well oiled machine.” One
particular manager might look good because his/her decisions occurred in combination with decisions of
another manager and that combination worked just right at that given moment in that given place. Both
managers benefit and are so evaluated. Can a performance model be developed that would consider the
wide possibilities that could result from the various combinations of decisions and events? Cost-benefit
approach would have to be used.
A chemical change results from a combination of individual factors creating a different product. With
enough experimentation, feedback, and knowledge, one can predict the product that will result from the
combinations of different factors. A performance evaluation model could be developed in a similar
fashion.
