Scenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner. Ben was particularly disturbed about the amount spent on corrugated boxes purchased from Southeastern Corrugated. Ben said, I dont like the salesman from that company. He comes around here acting like he owns the place. He loves to tell us about his fancy car, house, and vacations. It seems to me he must be making too much money off of us! Jeff responded that he heard Southeastern Corrugated was going to ask for a price increase to cover the rising costs of raw material paper stock. Jeff further stated that Southeastern would probably ask for more than what was justified simply from rising paper stock costs. After the meeting, Ben decided he had heard enough. After all, he prided himself on being a results-oriented manager. There was no way he was going to allow that salesman to keep taking advantage of Coastal Products. Ben called Jeff and told him it was time to rebid the corrugated contract before Southeastern came in with a price increase request. Who did Jeff know that might be interested in the business? Jeff replied he had several companies in mind to include in the bidding process. These companies would surely come in at a lower price, partly because they used lower-grade boxes that would probably work well enough in Coastal Products process. Jeff also explained that these suppliers were not serious contenders for the business. Their purpose was to create competition with the bids. Ben told Jeff to make sure that Southeastern was well aware that these new suppliers were bidding on the contract. He also said to make sure the suppliers knew that price was going to be the determining factor in this quote, because he considered corrugated boxes to be a standard industry item. Is Ben Gibson acting legally? Is he acting ethically? Why or why not?

Beagle Clothiers uses a weighted score for the evaluation and selection of its suppliers of trendy fashion garments. Each supplier is rated on a 10-point scale (10 = highest) for four different criteria: price, quality, delivery, and flexibility (to accommodate changes in quantity and timing). Because of the volatility of the business in which Beagle operates, flexibility is given twice the weight of each of the other three criteria, which are equally weighted (the sum of the four weights equals 1). The table shows the scores for three potential suppliers for the four performance criteria. 9 Rating Supplier A Supplier B Supplier C 8 5 Criteria 1. Price 2. Quality 3. Delivery 8 9 6 5 6 8 4.

Brewery Ipana Oy has found some potential long-time partners in the restaurant business. To optimize the supply chain, the company is negotiating for contracts that would allow all production in the coming years to be sold to these partners. The contracts aim to shift production to 20 liter barrels of beer, which would become the sole product of Ipana Oy. In case the negotiations are successful, Ipana Oy estimates its typical year would look as follows: the quantity shipped to the customer is 18000 units at a price of 300 €/unit. The gross profit percentage is 40 % and the yearly fixed costs are 1500000 €. (Additional text: The variable cost per unit [€/unit] for products that would be produced in the scenario above is 180 [€/unit].) Question: Calculate the critical sales price in the estimate [€/product].

Designing the Distribution Network for Michael’s Hardware Ellen Lin, vice president of supply chain at Michael’s Hardware, was looking at the financial results from the past quarter and thought that the company could significantly improve its distribution costs, especially given the recent expansion into Arizona. Transportation costs had been very high, and Ellen believed that moving away from LTL shipping to Arizona would help lower transportation costs without significantly raising inventories. Michael’s had 32 stores each in Illinois and Arizona and sourced its products from eight suppliers located in the Midwest. The company began in Illinois and its stores in the state enjoyed strong sales. Each Illinois store sold, on average, 50,000 units a year of product from each supplier (for annual sales of 400,000 units per store). The Arizona operation was started about five years ago and still had plenty of room to grow. Each Arizona store sold 10,000 units a year from each supplier (for…
