CHAPTER 12
TACTICAL DECISION MAKING
QUESTIONS FOR WRITING AND DISCUSSION
1. A tactical decision is short-run in nature; it
involves choosing among alternatives with
an immediate or limited end in view. A stra-
tegic decision involves selecting strategies
that yield a long-term competitive advan-
tage.
2. Depreciation is an allocation of a sunk cost.
This cost is a past cost and will never differ
across alternatives.
3. The salary of a supervisor in an accept or
reject decision is an example of an irrelevant
future cost.
4. If one alternative is to be judged superior to
another alternative on the basis of cash-flow
comparisons, then cash flows must be ex-
pressed as an annual amount (or periodic
amount); otherwise, consideration must be
given to the time value of the nonperiodic
cash flows.
5. Disagree. Qualitative factors also have an
important bearing on the decision and may,
at times, overrule the quantitative evidence
from a relevant costing analysis.
6. The purchase of equipment needed to pro-
duce a special order is an example of a fixed
cost that is relevant.
7. Relevant costs are those costs that differ
across alternatives. Differential costs are the
differences between the costs of two alter-
natives.
8. Depreciation is a relevant cost whenever it is
a future cost that differs across alternatives.
Thus, it must involve a capital asset not yet
acquired.
9. Past costs can be used as information to
help predict future costs.
10. Yes. Suppose, for example, that sufficient
materials are on hand for producing a part
for two years. After two years, the part will
be replaced by a newly engineered part. If
there is no alternative use of the materials,
then the cost of the materials is a sunk cost
and not relevant in a make-or-buy decision.
11. Complementary effects may make it more
expensive to drop a product, as the dropped
product has a negative impact on other
products.
12. A manager can identify alternatives by using
his or her own knowledge and experience
and by obtaining input from others who are
familiar with the problem.
13. No. Joint costs are irrelevant. They occur
regardless of whether the product is sold at
the split-off point or processed further.
14. Yes. The incremental revenue is $1,400,
and the incremental cost is only $1,000,
creating a net benefit of $400.
15. Regardless of how many units are pro-
duced, fixed costs remain the same. Thus,
fixed costs do not change as product mix
changes.
16. No. If a scarce resource is used in producing
the two products, then the product providing
the greatest contribution per unit of scarce
resource should be selected. For more than
one scarce resource, linear programming
may be used to select the optimal mix.
17. If a firm is operating below capacity, then a
price that is above variable costs will in-
crease profits. A firm may sell a product be-
low cost as a loss leader, hoping that many
customers will purchase additional items
with greater contribution margins. Grocery
stores often use this strategy.
18. Different prices can be quoted to customers
in markets not normally served, to noncom-
peting customers, and in a competitive bid-
ding setting.
19. Linear programming is used to select the
optimal product mix whenever there are mul-
tiple constrained scarce resources.
20. An objective function is the one to be max-
imized (or minimized) subject to a set of
constraints. A constraint restricts the possi-
ble values of variables appearing in the ob-
jective function. Usually, a constraint is con-

2. 339922
cerned with a scarce resource. A constraint
set is the collection of all constraints for a
given problem.
21. A feasible solution is a solution to a linear
programming problem that satisfies the
problem’s constraints. The feasible set of
solutions is the collection of all feasible solu-
tions.
22. To solve a linear programming problem
graphically, use the following four steps: (1)
graph each constraint, (2) identify the feasi-
ble set of solutions, (3) identify all corner
points in the feasible set, and (4) select the
corner point that yields the optimal value for
the objective function. Typically, when a li-
near programming problem has more than
two or three products, the simplex method
must be used.

1. ($30 × 2,000) + ($60 × 4,000) = $300,000
2. Juno Hera
Contribution margin $30 $60
÷ Pounds of material ÷ 2 ÷ 5
Contribution margin/pound $15 $12
Norton should make the 2,000 units of Juno, then make Hera.
2,000 units of Juno × 2 = 4,000 pounds
16,000 pounds – 4,000 pounds = 12,000 pounds for Hera
Hera production = 12,000/5 = 2,400 units
Product mix is 2,000 Juno and 2,400 Hera.
Total contribution margin = (2,000 × $30) + (2,400 × $60)
= $204,000

Price $ 9.00 $30.00 $35.00
Variable cost 6.00 20.00 10.00
Contribution margin $ 3.00 $10.00 $25.00
÷ Machine hours ÷ 0.10 ÷ 0.50 ÷ 0.75
Contribution margin/MHr. $30.00 $20.00 $33.33
The company should sell only the deluxe unit with contribution margin per
machine hour of $33.33. Sealing can produce 20,000 (15,000/0.75) deluxe units
per year. These 20,000 units, multiplied by the $25 contribution margin per
unit, would yield total contribution margin of $500,000.
2. Produce and sell 12,000 deluxe units, which would use 9,000 machine hours.
Then, produce and sell 50,000 basic units, which would use 5,000 machine
hours. Then produce and sell 2,000 standard units, which would use the re-
maining 1,000 machine hours.
Total contribution margin = ($25 × 12,000) + ($3 × 50,000) + ($10 × 2,000)
= $470,000

1. Model A-4 Model M-3
Contribution margin $24 $ 15
÷ Hours on lathe ÷ 6 ÷ 3
Contribution margin/hours on lathe $ 4 $ 5
Model M-3 has the higher contribution margin per hour of drilling machine
use, so all 12,000 hours should be spent producing it. If that is done, 4,000
(12,000 hours/3 hours per unit) units of Model M-3 should be produced. Zero
units of Model A-4 should be produced.
2. If only 2,500 units of Model M-3 can be sold, then 2,500 units should be pro-
duced. This will take 7,500 hours of drilling machine time. The remaining
4,500 hours should be spent producing 750 (4,500/6) units of Model A-4.

1. Model 14-D Model 33-P
Contribution margin $ 12 $ 10
÷ Hours on lathe ÷ 4 ÷ 2
Contribution margin/hours on lathe $ 3 $ 5
Model 33-P has the higher contribution margin per hour of lathe use, so all
12,000 hours should be spent producing it. If that is done, 6,000 (12,000
hours/2 hours per unit) units of Model 33-P should be produced. Zero units of
Model 14-D should be produced.
2. If only 5,000 units of Model 33-P can be sold, then 5,000 units should be pro-
duced. This will take 10,000 hours of lathe time. The remaining 2,000 hours
should be spent producing 500 (2,000/4) units of Model 14-D.

irrelevant because these are sunk costs.

Heath should sell the Silverado and buy the Dodge Ram because it provides a
net savings of $1,600.
Note: Heath should consider the qualitative factors. If he restored the Silvera-
do, how much longer would it last? What about increased license fees and in-
surance on the newer car? Could he remove the stereo and put it in the
Dodge Ram without decreasing the Silverado’s resale value by much?

PROBLEMS
12–21
Steps in Austin’s decision:
Step 1: Define the problem. The problem is whether to continue studying at his
present university, or to study at a university with a nationally recog-
nized engineering program.
Step 2: Identify the alternatives. Events A and B. (Students may want to include
event I—possible study for a graduate degree. However, future events
indicate that Austin still defined his problem as in Step 1 above.)
Step 3: Identify costs and benefits associated with each feasible alternative.
Events C, E, F, and I. (Students may also list E and F in Step 5—they are
included here because they may help Austin estimate future income
benefits.)
Step 4: Total relevant costs and benefits for each feasible alternative. No specif-
ic event is listed for this step, although we can intuit that it was done,
and that three schools were selected as feasible since event J mentions
that two of three applications met with success.
Step 5: Assess qualitative factors. Events D, E, F, G, and H.
Step 6: Make the decision. Event J is certainly relevant to this. (What did Austin
ultimately decide? He decided that a qualitative factor, his possible fu-
ture with his long-time girl friend was most important and stayed at his
current school. After graduation, he was hired by a major aeronautical
engineering firm. By the way, he and his girl friend broke up shortly af-
ter his decision to stay was made. )

would increase by $12,800:
Accept Reject
Revenues (2 × $1.85 × 8,000) $29,600 $0
Variable expenses 16,800 0
Total $12,800 $0
Pat’s divisional profits would increase by $18,400:
Accept Reject
Revenues ($32 × 8,000) $ 256,000 $0
Variable expenses:
Direct materials ($17 × 8,000) (136,000) 0
Direct labor ($7 × 8,000) (56,000) 0
Variable overhead ($2 × 8,000) (16,000) 0
Component (2 × $1.85 × 8,000) (29,600) 0
Total relevant benefits $ 18,400 $0
2. Pat should accept the $2 price. This price will increase the cost of the com-
ponent from $29,600 to $32,000 (2 × $2 × 8,000) and yield an incremental bene-
fit of $16,000 ($18,400 – $2,400).
Steve’s division will see an increase in profit of $15,200 (8,000 units × 2 com-
ponents per unit × $0.95 contribution margin per component).
3. Yes. At full price, the total cost of the component is $36,800 (2 × $2.30 ×
8,000), an increase of $7,200 (= 2 × 8,000 × 0.45) over the original offer. This
still leaves an increase in profits of $11,200 ($18,400 – $7,200). (See the an-
swer to Requirement 1.)

MANAGERIAL DECISION CASES
12–31
1. Pamela should not have told Roger about the deliberations concerning the
Power Department. She is obligated by Standard II-1 to “keep information
confidential except when disclosure is authorized or legally required.” She
had been explicitly told to keep the details quiet but deliberately informed the
head of the unit affected by the potential decision. By revealing the informa-
tion, Pamela also initiated an activity that would prejudice her ability to carry
out her duties ethically (III-2).
2. The romantic relationship between Pamela and Roger sets up a conflict of in-
terest for this particular decision, and Pamela should have withdrawn from
any active role in it. However, she should definitely provide the information
she currently has about the cost of eliminating the Power Department. This is
required by standard IV-2, which states that “all relevant information that
could reasonably be expected to influence an intended user’s understanding”
should be disclosed. Moreover, she has the obligation to communicate infor-
mation fairly and objectively (IV-1). These ethical requirements, however, do
not in any way prevent Pamela from discussing the qualitative effects of eli-
minating the Power Department. The effects on workers, community relations,
reliability of external service, and any ethical commitments the company may
have to its workers should all enter into the decision. If I were Pamela, I would
communicate the short-term quantitative effects and express my concerns
about the qualitative factors. I might also project what the costs of operating
internally would be for the next five years and compare that with estimates of
the costs of external acquisition.

MEMO
TO: Central University President
DATE: November 15, 2008
SUBJECT: Decentralization of Continuing Education
In recommending whether to centralize or decentralize continuing education (CE),
I have first focused on the economic implications. The income statements, show-
ing a favorable trend for CE, are misleading, at least in terms of their implications
for centralization. Tuition revenues will be present whether we centralize or de-
centralize and, therefore, are not relevant to the decision. Department heads are
already heavily involved in scheduling and staffing off-campus and evening
courses, and individual faculty are largely responsible for generating our noncre-
dit offerings. Thus, it would be difficult to argue that decentralizing CE would
have any adverse impact on the level of tuition revenues.
In a similar vein, one can argue that the operating costs for evening and noncre-
dit courses and the direct costs for off-campus offerings are also irrelevant.
These costs, which consist of instructional wages, rental of facilities, and sup-
plies, will be incurred regardless of whether CE is centralized or decentralized.
This leaves two categories of costs, indirect costs and administration, which af-
fect the decision. These categories include advertising, secretaries, assistants,
and other support personnel. If we choose to decentralize, all of these costs, with
the exception of the director’s salary and advertising, can be avoided. Further-
more, because the director will be teaching in her department, some of her salary
is avoidable as well ($20,000). The total avoidable costs are outlined as follows.
Administrationa
$ 82,000
Indirectb
410,000
Total $492,000
a
[$112,000 – ($50,000 – $20,000)] = $82,000
b
Indirect costs – Advertising = $440,000 – $30,000

33. 442233
12–32 Concluded
I have retained the budget for advertising and would recommend that this amount
be allocated to the individual colleges in proportion to the evening and off-
campus revenues generated by each college.
As you can see, the savings from decentralization are significant. This presumes,
of course, that the overhead of the individual units will not increase because of
the added responsibilities. I have discussed this matter with my department
heads and with the deans of the other colleges. They all seem to feel that the ad-
ditional administrative work can be easily absorbed by their existing staff. Thus, it
seems that the promised savings are real.
In choosing to decentralize, however, we do lose some intangible benefits. First,
we no longer have one individual who can be contacted by outside parties. In-
stead, we have numerous individuals involved. This may prove to be frustrating
for some of those whom we serve, and it is possible that they will perceive a drop
in service quality.
There is also a risk that some units will not exert the effort needed to provide
good service. Accountability is more diffuse, and some department heads may
feel that they have more than enough to do without continuing education. This
problem can be alleviated to some extent by localizing the CE responsibility at
the college level, rather than at the departmental level.
I am personally convinced that a decentralized CE will work as well, if not better,
than our current arrangement. Given our current budgetary crisis, I would rather
risk reducing the quality of service for CE than risk reducing the quality of service
for our main programs. Therefore, I strongly recommend that CE be decentralized
and that the savings from this action be used to maintain the quality of our on-
campus programs.
