Operations Management/Math Problem
B&L Inc. Case Study
Brian Wilson, materials manager at B&L Inc. in Lancaster, Pennsylvania, was considering a proposal
from his purchasing agent to outsource manufacturing for an outrigger bracket. It was the end of April
and Mr. Wilson had to evaluate the proposal and make a decision regarding whether to proceed.
B&L Inc. Background
B&L Inc. manufactured trailers for highway transport trucks. The company comprised three divisions: the
Trailer, Sandblast & Paint, and Metal Fabricating Divisions. Each division operated as a separate profit
center, but manufacturing operations between each were highly integrated. The Metal Fabricating
Division produced most of the component parts of the trailers, the Trailer Division performed the
assembly operations, and the Sandblast & Paint Division was responsible for completing the sandblasting
and final painting operation. B&L manufactured approximately 40 trailers per year, with about two-thirds
produced during the period from November to April.
The Outrigger Bracket
The outrigger bracket, part number T-178, was an accessory that could be used to secure oversized
containers. The bracket consisted of four component parts welded together, and each trailer sold by B&L
had 20 brackets—10 per side.
The Metal Fabricating Division was currently manufacturing the outrigger bracket. The subassembly
parts—T-67, T-75, T-69, and T-77—were processed on a burn table, which cut the raw material to size.
Although the burn table could work with eight stations, this machine had only been operating with one
station. The final assembly operation, T-70, was performed at a manual welding station.
Manufacturing lead time for the outrigger bracket was two weeks. However, the Metal Fabricating
Division had been able to coordinate supply and production with assembly operations. Consequently,
finished inventory levels of the outrigger bracket were kept to a minimum. B&L's inventory holding costs
were 20 percent per annum.
The Outsourcing Decision
In an effort to reduce costs, the purchasing agent, Alison Beals, who reported to Brian Wilson, solicited
quotes from three local companies to supply the outrigger bracket. Mayes Steel Fabricators (Mayes), a
current supplier to B&L for other components, offered the lowest bid, with a cost of $108.20, FOB B&L.
Brian met with the controller, Mike Carr, who provided a breakdown of the manufacturing costs for the
outrigger bracket. Looking at the spreadsheet, Mike commented: “These are based on estimates of our
costs from this year's budget. Looking at the material, labor, and overhead costs, I would estimate that the
fixed costs for this part are in the area of about 20 percent. Keep in mind that it costs us about $75 to
place an order with our vendors.” Exhibit 1 provides B&L's internal cost breakdown and details from the
quote from Mayes.
Brian expected that B&L would have to arrange for extra storage space if he decided to outsource the
outrigger bracket to Mayes, who had quoted delivery lead time of four weeks. Because Mayes was local
and had a good track record, Brian didn't expect the need to carry much safety stock, but the order
quantity issue still needed to be resolved.
B&L was operating in a competitive environment and Brian had been asked by the division general
manager to look for opportunities to reduce costs. As he sat down to review the information, Brian knew
that he should make a decision quickly if it was possible to cut costs by outsourcing the outrigger bracket.
Analyze the information and write a report to Brian summarizing your recommendations. Be sure
to include your calculations for supporting your recommendations. To guide your report and
expectations see the Case Study rubric in the syllabus or in the course information area. Submit
your report in your week 4 drop-box labeled Midterm Exam B&L Inc. Case Study.
