Cost by cost, this AC239 Unit 10 incremental decision analysis weighs a make-or-buy proposal, keeps only what differs between the two options, and recommends with its caveats stated. Searches like "ac 239 unit 10 assignment example", "ac239 unit 10 sample" and "ac239 unit 10 example" land here.
What a finished AC239 Unit 10 incremental decision analysis looks like
Three parts. The first is a cost inventory: every cost the problem mentions for producing the component internally, direct materials, direct labor, variable overhead, a supervisor's salary, depreciation on the equipment and a share of plant-wide fixed overhead, each followed by a verdict, relevant or not, and a short reason. The second is the incremental table, with columns for make, buy and the difference. Only relevant items appear in it: the variable production costs, the supervisor's salary if the position would be eliminated, the supplier's price, and the contribution from a product line that the freed capacity could support. The difference column is summed to a single figure favoring one option. The third part is a recommendation that states the figure, then weighs supplier reliability, quality control and the risk of losing the skill in-house.
How a AC239 Unit 10 example is structured
The cost inventory comes first, so a reader who disagrees with the answer can find the one classification behind the disagreement. Each verdict rests on a single test, stated once at the top: does this amount differ between making and buying? Depreciation on existing equipment fails it, since the cost was incurred when the machine was bought. Allocated plant overhead fails it unless the problem says some of it would disappear. The incremental table is built only from items that pass, which keeps it short and makes each line defensible. Opportunity cost gets its own labeled line rather than being folded into the buy column, because it is the item graders most often find missing. The recommendation states the incremental figure first, then turns to the factors the table cannot hold, and ends on a clear call rather than a list of considerations.
One test, stated at the top
Does the amount differ between making and buying? Every cost in the problem is run through that question before any arithmetic, and the verdicts are listed with reasons.
Costs that fail the test
Depreciation on equipment already owned and plant overhead allocated from elsewhere. Each is named and excluded, with a note if the problem says any part would actually disappear.
The make, buy and difference columns
Variable production costs, the avoidable supervisor's salary and the supplier's price, lined up so the difference column reads as the saving from one choice.
Freed capacity, priced
If the space could make another product, that product's contribution is lost by continuing to make the component. It sits on its own labeled line.
The call and what the table leaves out
The incremental figure stated first, then supplier dependability, quality control and the loss of an in-house skill, ending on a definite recommendation.
Where marks go in AC239 Unit 10
Allocated fixed overhead carried into the make column is the classic loss here. It makes internal production look expensive, and the analysis recommends buying on the strength of a cost that would continue regardless. Graders deduct heavily because excluding it is the unit's central lesson. Depreciation on existing equipment treated as avoidable is the same mistake in a different line. Missing opportunity cost is next, and in problems that mention an alternative use for the space it can reverse the correct answer. A comparison of the supplier's price against the full cost per unit on the product cost sheet is the same error in its most common disguise. Recommendations that list qualitative factors without deciding lose judgment marks, as do ones that ignore those factors entirely when the incremental saving is small.

AC239 Unit 10 questions, answered
What changes if the proposal is to drop a product line instead?
The same test applies, but the costs that pass are different. Dropping a line loses its revenue and its variable costs, saves only the fixed costs that would truly disappear, and often leaves allocated overhead to be absorbed by the remaining lines. The sample's structure carries over: cost inventory with verdicts, an incremental table, and a recommendation that addresses effects on the lines that remain.
When is depreciation relevant?
Almost never as depreciation itself, since it spreads a cost already incurred. What can be relevant is the cash the equipment would bring if sold, or a replacement purchase one option would require. If the problem says the machine could be sold for a stated amount on outsourcing, that amount enters the buy column as a cash inflow, and the sample labels it that way.
How long should the qualitative section be?
Long enough to change the recommendation if it should. When the incremental difference is large, a few sentences on supplier risk and quality suffice. When it is small, those factors may decide the case, and the section grows accordingly. AC239 rubrics usually reward a definite recommendation that acknowledges the factors over a balanced list that never commits.
