Stage 1: Setting Goals and Objectives

Organizations must set objectivesto provide clear guidance.

Tangible objectives provide benchmarks

against which to measure performance.

Intangible objectives: may provide guidance, but tend to be abstract and are difficult to measure


13-5

Determine target selling price. Determine target cost.

Determine target profit Deduct target return on sales Result is target cost

Compare target cost to currently feasible total cost. The difference is the cost-reduction

achieve the cost-reduction target.

Identification of Relevant Costs and Benefits

Relevant costs are costs to be incurred at some future time and

that differ for each option available to the

decision maker.

past are not relevant. Costs incurred in the past are not relevant.

They are called called sunk costs.

Decision: Trading an old car for a new car.

Identification of Relevant Costs and Benefits

Stage 3: Evaluating Alternatives

3. Measure the benefits and costs of each set of outcomes.

1. List decision alternatives in the

order the decisions must

be made.

2. Trace the path of each

decision to its ultimate

outcome.

Consider qualitative aswell as quantitative factors.


13-11

Anticipating future outcomes of each action

Stage 3: Evaluating Alternatives

Consider the pastAlthough past costs are

sunk and thereforeirrelevant, they can beused to help estimate

future costs that are relevant.

Completely new products Use prototype products

to estimate costs. Rely on consultantswho have knowledgeof similar products.

Decision Tree A useful decision aid in diagramming

decisions and alternative outcomes Allows an evaluation of the costs and

benefits of each alternative (limb) Steps in creating a decision tree:

Display decision alternatives in order

Identify the set of outcomes resulting from each decision path

Measure costs and benefits of each set of outcomes

Outsourcing or Make-or-Buy Decision

When the company needs goods or services, should they be made internally or bought

externally?

When goods or services are

acquired externally, it is called

outsourcing.


13-17



13-18

Identify the fixed costs that we could avoid if we outsource.

Identify the variable costs

that would disappear if we

outsource.

Identify the new variable costs that we would

incur if we outsource.

Lets look at a make-or-buy decision faced by the management of Thor Company.



13-20


Thor Co. manufactures 20,000 of part 457 that is currently used in one of its products. The costs to

make this part are:

Direct materials per unit $ 9.00 Direct labor per unit 5.00 Variable overhead per unit 1.00 Fixed overhead 180,000 Allocated common costs 100,000


13-21

Fixed manufacturing overhead is the cost of leasing andoperating the equipment necessary to produce part 457.

Thor Co. manufactures 20,000 of part 457 that is currently used in one of its products. The costs to

make this part are:

13-22

Common costs are allocated on the basis of direct labor hours.

Total unit cost of $29 is based on 20,000 parts produced each year.

An outside supplier has offered to provide the 20,000 parts at a cost of $25 per part.

Should we accept the suppliers offer?Should we accept the suppliers offer?

What is the relevant unit cost of making part 457?

Advantage of making20,000 units ($25.00 $24.00) = $20,000



13-28

If Thor could use the space currently being used to makePart 457 for another purpose, resulting in a cost savings of

$45,000, would you change your decision?

Yes. The cost savings (opportunity cost) of $45,000overcomes the $20,000 disadvantage of buying.

Now there is a $25,000 advantage to buying.

The real issue is the most profitable use of the space.



13-29

Pitfalls of Outsourcing

Loss of sensitive

information to supplier.

Freed-up resources

are not used as planned.

Supplier quality is not as high as

anticipated.

Customers may object.

Customer contact may be reduced.

Supplier technology and knowledge base may not be as

anticipated.

Decision to Add or Drop a Product, Service, or Business Unit

If we shut down If we shut down our U.S. Digital watch line, we

might anger our American

customers.

. . . Not to mention the bad press!

That is why we have to consider

the relevant benefits and the relevant costs

BEFORE making a final decision.


13-31

That is why we have to consider

the relevant benefits and the relevant costs

BEFORE making a final decision.

Lets get started.The digital line

has become lessprofitable and it is

difficult to competein the market.

. . . Not to mention the bad press!

If the digital watch line is dropped, the fixed general factory overhead fixed general factory overhead and general general administrative expenses administrative expenses will be allocated

to other product lines.

The equipment used to manufacturedigital watches has no resale

value or alternative use.



13-35



Should Market retain or dropShould Market retain or dropthe digital watch line?the digital watch line?



13-36

DECISION RULEDECISION RULEMarket should drop the digital watch segment only if its fixed cost savings

exceedexceed lost contribution margin.

Lets look at this solution.Lets look at this solution.

Less fixed costs that can be avoided Salary of the line manager 90,000$ Advertising - direct 100,000 Rent - factory space 70,000 260,000 Net disadvantage (40,000)$

Should we drop the digitalwatch segment?



13-38

The same result can also be obtainedby preparing a differential analysis showing operating results with and without the digital watch segment.

Lets look at this approach.Lets look at this approach.

13-40

Example: If the idled facilities can be used to makea product generating $350,000 per year in contribution

margin, with no other change in fixed costs,might this change your decision?

Keeping the digital watch product line may have an opportunity cost that we

have not yet considered.The opportunity cost of retaining the digitalwatch line is measured by the differentialprofits given up if the next best use of the

production facilities is rejected.

Measuring cost savings and lost revenues from closing a business unit is only part of the story.

The closing will impact . . . Employees personal lives, Morale of retained employees, The community at large.

Which costs are relevant to the decision to replace an old machine with a new machine?Which costs are relevant to the decision to

replace an old machine with a new machine?

Old machine cost $5,400 when purchased. Old machine has a book value of $1,500. Purchase price of a new machine is $10,000. New machine will reduce labor from $12.00 to

$11.00 per unit. New machine is expected to last two years. Repairs to old machine would be $4,600 and

would allow two more years of productivity. Power for either machine is expected to be $2.50

per unit. Expected level of output: 1,000 units per year.

Prices are determined by the market, subjectto costs that must be covered in the long run.

Prices are based on costs, subject toreactions of customers and competitors.

A travel agency offers Worldwide Airways $150,000 for a round-trip flight from Japan to Hawaii on a jumbo jet.

Worldwide usually gets $250,000 in passenger ticket revenue from this flight.

The airlines is not currently planning to add any new routes and has two planes that are idle and could be used to meet the needs of the agency.

The next screen shows cost data developed by managerial accountants at Worldwide.

Revenue: Passenger 250,000$ Cargo 30,000 Total 280,000$ Expenses: Variable expenses 90,000 Allocated fixed expenses 100,000 Total 190,000 Profit 90,000$

Since the charter will contribute to fixed costs andSince the charter will contribute to fixed costs andWorldwide has idle capacity, the company shouldWorldwide has idle capacity, the company should

accept the flight.accept the flight.



13-52

What if Worldwide had no excess capacity? If Worldwide adds the charter, it will have to cut

its least profitable route that currently contributes $80,000 to fixed costs and profits.

Should Worldwide still accept the charter?

Special price for charter 150,000$ Variable cost per flight 90,000$ Reservation cost savings (5,000) Variable cost of charter 85,000 Opportunity cost: Lost contribution on route 80,000 165,000 Total (15,000)$

Assuming no excess capacity

Worldwide has no excess capacity, so it should reject the special charter, or try to

renegotiate a higher price.



13-54

With excess capacity . . . Relevant costs usually will be the variable costs

associated with the special order.

Without excess capacity . . . . Same as above but opportunity costs of using

the firms facilities for the special order are also relevant.
