Teaching Commentary
OVERVIEW
This is an excellent short case that blends basic cost analysis themes with strategic management themes. The ostensible
topic is cost analysis for bidding in a small job shop. But the case also deals with activity-based costing and the blending
of business analysis, strategic analysis, and cost analysis. It is a great case to see the interactions among these various
themesnot much can be done here with any of them, but they all are clearly relevant, once the context is clarified.
Thus the case is a good one to review some basic, conventional cost management themes while clearly
demonstrating the limitations of the conventional themes and the relevance of the “SCM” themes. “Cost analysis for
decision-making” here must go well beyond the conventional framework.
ANSWERS TO ASSIGNMENT QUESTIONS
Question 1
The short answer here is that Exhibit 3 suggests there would be no increment to “PFMOH” from producing one
more order. These are “fixed” costs that are clearly not closely related to volume in the short run.
A closer examination of Exhibit 3 raises other issues as well:
1. Notice the dramatic swings in monthly “PFMOH” over the thirtytwo months shown in the exhibit
from $3,536 to $17,196 between January and February of 1984; from $11,325 to $1,161 between
2. The cost total was about $99,000 for 1984 and about the same for 1985 (if December 1984 and January
1985 are averaged to correct for fairly obvious cut-off problems). For 1986, the total seems to be
running about $205,000, twice the earlier annual rate. This suggests that Smith’s strategy to increase
10-2
3. For whatever reasons, the regression equations
in Exhibit 3 are essentially meaningless. The
very low R2 statistics and statistically
students see this?
Question 2
However one interprets Exhibit 3, it should be
clear to students that there is not likely to be any
incremental “PFMOH” for the milk crate order. These
costs are not volume sensitive, order by order.
A second rule of thumb for BP can be derived
from the 2.33 multiplier mentioned in the case (“sales
price should equally 2.33 (material + labor)). This
crates of $4.32 ($1.85 2.33) and variable overhead of
$.69/unit, using the “16% of sales” estimate in Exhibit
1.
Why is this estimate$.69/unitso much
different from the $.18/unit figure that comes from the
same overall cost structure? This difference can be
explained as follows:
1. Estimated Direct Materials + Direct Labor for 1986
is $515,000, per Exhibit 1.
5. For milk crates, the ratio of materials to labor is
about twelve times (1.75/.14). This indicates that
milk crates are a very low labor product, versus
four times less labor intensive than average
(~12x/~3x), a better estimate would be $.69 ÷ 4 =
~$.17/unit.
8. This estimate$.17/unitmatches very closely
the $.18/unit estimate based strictly on labor hours
(running hours).
Question 3
Industry Average Pricing for Milk Crates
The presumed market price of $3.00 implies
competitors discount the normal, rule of thumb price
here by almost 10%.
Industry Average Cost
Direct Material +
Direct Labor $1.81 (Same as for BP?)
Variable Overhead .56 (.31 DM + DL)
Question 4
Strategically Relevant Cost of Milk Crates?
No argument
Variable Overhead?
1. At $13/Running Hr. = $.18
(13 2084/150,000)
Probably the most likely estimate is $.18.
Fixed Overhead
1. The 2.33 rule implies (35% Normal Sales Price
$1.51 per unit of $4.31)

profitable in the long-run. Avoid the
temptation to cheat on your strategy, even in
the short run.

Level 3: Crates are very simple to make
An Activity Based Costing Perspective
Fixed Cost/Running Hour for Vanilla Products:
1. Factory OH 100,000 (other $105 is
complexity related)
4. 2605 x $12 ÷ 150,000 = ~$.20/unit
Labor goes down from $.14 to ~$.09 with .80 up time
Full cost, complexity adjusted, may only be about
2.25/unit.
$2.25
Fixed $.20
At a “true” full cost of $2.25, BP could bid $2.90 and
still show a full cost profit of 20%+.
If they are easy for us, they are easy for
everyone else, too.
The easy products, over time, will go to the
low cost producers That is not BP (a small, niche
Crates do not fit BP’s strategy and should be
avoided. Management should devote the capacity to
products that justify the strategy of high fixed
cost/niche products/differentiation focus.
Level 5: There is still the “Factory within a Factory”
perspective
Crates are a great product to “baseload the
10-5
least average contribution margin all the way down to a
price of $2.40.
As long as the industry uses “average rules of
Price the specialties high
Price the vanilla low
Make sure you understand the cost structure for
simple vs. complex products.
In general, the idea in Question 4 is for
Question 6 (Question 5 on following page)
The key idea here is for students to think about
BP’s overall strategic positioning. Without the milk
crate order, the business will be barely profitable in
1986, a good business year, in spite of Michael Smith’s
two-year repositioning efforts.
Smith has moved the business heavily into
specialty products. How can we tell?
1. The product mix for 1986, heavy on specials,
will show contribution margin (CM) of
~$490,000 on ~15,000 running hours, per
Exhibits 1 and 3.
$32.67/running hour.
3. For a very easy, “vanilla” product, such as
facilities or demand more overhead support
should show much higher CM/running hour
than vanilla products.
5. But, let’s assume crates are really overpriced
at $3.00. The industry is ignorant of “ABC”
[$2.55 $2.10 = $.45 x 150,000 = $67,500 ÷
2,084 = ~$32.40].
8. Thus, the conclusion stands that BP’s current
average CM/running hour is far too low, given
the heavy mix of specialty products. The
“specials” are underpriced.
9. If any other commodity items are overpriced,
here if Smith charged prices based on complexity-
adjusted full cost?
He has gone from thirty to fifty different
products, relying on “CM” pricing. But his fixed
overhead hasn’t stayed fixed! Production Fixed
averaging ~40% CM on the overall business in 1986
(~$490,000/~$1,200,000 = ~40%). At this rate, the
Question 5
It should be clear from Question 6 that Smith’s
real problem is how to increase the prices on “specials”
without losing the business. In situations where “ABC”
issues are not well understood, it is common to see
There is no obvious answer here. The likely
range of competing bids, per the case, is from $2.90 to
$3.10.
The differentiation strategy/niche markets/high
cost and high margin perspective suggests not bidding
on milk crates. BP must find products that fit its
strategy.
TEACHING STRATEGY
We often use this case as the final class in the
many different “solutions” are plausible. The case is
likely to generate controversy in class, which reinforces
the basic ideas that cost analysis is a journey, not a
destination, and that the “goal” is better questions, not
definitive answers.
We start class with Question 1, expecting lots
class. Once the various analytic issues are raised, the
case will support as much discussion as time permits on
the fundamental question: What should Michael Smith
do, and why?
