The purpose of this case is to explore the question of make versus buy ? ?focusing


particularly on the contribution to overhead that is involved in a make-buy decision.




The case states that the reason for considering buying rather than making is the present


12 percent% defective rate. A supplier that machines its own castings could have a lower rate of


defects than Donley Brothers has; thus, the firm could quote a lower price, however, it is entirely


possible that the supplier will have a higher defect rate (Burt, Petcavage, & Pinkerton, 2010).


The prospective supplier is a foundry. There is some question as to whether using a


supplier for work in which it is not expert is good idea. Supply management history is replete


with supply managers who learned, to their sorrow, that just because a company excels in one


line of work, no guarantee exists for its excelling in a different line. One of the primary reasons


for buying instead of making is to take advantage of the specialty supplier and its proven ability


in a specialized field (Burt, et al., 2010).


Many presume that Donley Brothers can only buy or make. Actually, many companies


make part and buy part of their requirements for the same item (Burt, et al., 2010). In such


cases, the outside supplier becomes an accurate cost barometer for the firm?s internal


manufacturing operation. The answer to the sole-source question in this case could easily be that


the second source could be Donley itself. With present production at 90% percent of capacity,


partial use of an outside source might be a very practical solution.


Question 1: Should Bob Donley contract with Akron Foundry for finished castings?


Before Bob decides whether or not to contract with Akron, he should first investigate the


cause of the defective castings (Burt, et al., 2010). It may be that by means of new DONLEY BROTHERS CASE STUDY 3 manufacturing and inspection methods, Donley Brothers can stop or at least reduce the rejection


rate. If Donley Brothers finds ways to lower the rejection rate, it will stand to gain.


Donley Brothers, in cooperation with its supplier, should call in specialists to examine the


existing patterns, the methods of pouring, inspection methods employed, ability to detect


failures, and so forth. In short, a full-scale study should be made to be sure that all of the recent


developments in casting technology are being applied to this problem (Burt, et al., 2010). If this


full-scale study discloses that advanced casting technology is being fully exploited, then it is


proper for Bob Donley to start his consideration of the make-or-buy make or buy question.


The make-or-buy make or buy consideration should start with the most elementary


computations (Burt, et al., 2010). The cost of making 1,000 good castings is based on three


principle elements of cost: materials, labor, and overhead. One thousand and one hundred forty


(1,140) raw castings must be purchased and machined in order to provide the 1,000 good


finished castings required by Donley Brothers each year.


Table 1


Annual Cost to Make 1,000 Finished Castings


Materials (raw


$600 x


= $ 684,000




Labor 1,140


$156 x = $ 177,840 Overhead 1,140


$156 x = $ 177.840 1,140


= $1,039,680


Note: The cost to purchase 1,000 good finished castings is $1,000 x 1,000 $1,000,000.


On the face of things, it appears that purchasing the annual requirement of 1,000 finished


castings is less expensive ($1,000,000) than making the finished castings ($1,039,680).


However, such a conclusion overlooks the contribution to overhead resulting from making the DONLEY BROTHERS CASE STUDY 4 castings. Overhead at Donley Brothers currently is 100 percent% of direct labor, or $156 per


casting. Fifty percent of this overhead is fixed and 50 percent is variable. Thus, the true variable


(out-of-pocket) cost of making 1,000 good castings is:


Table 2


Annual Variable Cost to Make




$600 x 1,140 = $684,000




$156 x 1,140 = $177,840


Variable Overhead $ 78 x 1,140 = $ 88,920


= $950,760 Thus, the variable cost of making is less ($950,760) than buying ($1,000,000). A contribution of $49,240 to fixed overhead results if Donley Brothers makes the castings ? ?


provided that the firm is operating below capacity.


This analysis ignores any real costs of production disruptions and lost sales.


Investigations must be conducted into whether such costs are emotional or a real problem (Burt,


et al., 2010); . Iif real, then estimates should be made as to their size. The investigation should


also determine if any such costs could be avoided by maintaining a buffer stock of finished




Question 2: Would there be any dollar savings by contracting with Akron if Donley


Brothers?s machine shop were operating at full capacity?


This is a difficult question whose answer is it depends. If Donley Brothers were operating at full capacity but not turning down potentially profitable work, then making the


castings would still provide a contribution to fixed overhead. Under these conditions, if Donley DONLEY BROTHERS CASE STUDY 5 were to buy the finished castings, total fixed overhead would remain the same, resulting in other


production items being assessed a higher fixed overhead rate. This in turn would result in each


of these items becoming less profitable.


However, if as a result of buying the finished castings Donley Brothers can apply its


productive resources (plant, equipment, labor, and management) to items which yield a higher


contribution to fixed overhead and, hopefully, to profit, then it is in the firm?s best interest to buy


finished castings (Burt, et al., 2010).


Question 3: What are the dangers involved if Akron becomes the sole source for


Donley Brothers?


If Akron becomes the sole source for the castings, there are two major problems (Burt, et


al., 2010).:


? Donley Brothers is tied to Akron; t. They are locked in. If Akron fails to perform, then


Donley Brothers is in trouble.


? Donley Brothers will have an obligation to Akron that may be difficult to break. Akron


may tie its future to Donley Brothers, and loss of Donley Brothers' business may


financially bankrupt Akron.


As mentioned in the discussion section, a possible second source could be Donley Brothers itself.


Question 4: Who is responsible for the make-or-buy decision?


The make-or-buy decision is principally a management decision (Burt, et al., 2010). The


chief executive officer (CEO) of a small or medium-size firm normally would make the decision.


In larger firms, in some industries, the decision is sometimes made at a level below the CEO, yet


at an organizational level high enough to insure that the financial well-being of the firm is


properly considered. The decision maker should have reliable input from production, finance DONLEY BROTHERS CASE STUDY 6 (on the true cost of making), and supply management.


Question 5: What other suggestions can you make for improving the situation at


Donley Brothers?


It is possible that the terms and conditions of the purchase order under which the raw


castings presently are purchased are deficient (Burt, et al., 2010). Quality standards, the right of


source inspection (monitoring of the supplier?s production and quality control processes),


provision for damages, etc., all need to be covered in the purchase order.


Donley Brothers may find it cost effective to have a casting engineer review the present


supplier?s production process. Perhaps the number of holes and cracks can be reduced. Frequently, an industrial customer will find it to be in its best interests to provide technical


assistance to its suppliers.


Some of Donley?s present problems in the area of production disruptions could be


reduced or avoided were an adequate buffer stock of finished castings available (Burt, et al.,




Why select a casting shop to machine the castings? It appears possible that Bob Donley, the


supply manager, will not have done an adequate job of sourcing (Burt, et al., 2010). The


machined casting appears to be an excellent candidate for value analysis. What does the finished


casting do? What else would do the job? What would be the alternative cost? Are the


tolerances realistic? Are commercially available substitutes available? DONLEY BROTHERS CASE STUDY 7 DONLEY BROTHERS CASE STUDY 8
