- 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?arrow_forwardScenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner.

- Over the past 12 months, Super Toy Mart has experienced a demand variance of 10,250 units and has produced an order variance of 12,050 units. Part 2 a) The bullwhip measure for Super Toy Mart is ______ (round your response to two decimal places). Part 3 b) If Super Toy Mart had made a perfect forecast of demand over the past 12 months and had decided to order 1/12 of that annual demand each month, the bullwhip measure would have been ______ (round your response to the nearest whole number.)arrow_forwardDemand for stereo headphones and music players for joggers has caused Nina Industries to grow almost 50 percent over the past year. The number of joggers continues to expand, so Nina expects demand for headsets to also expand, because, as yet, no safety laws have been passed to prevent joggers from wearing them. Demand for the players for this year was as follows: MONTH DEMAND (UNITS) January 4,150 February 4,250 March 3,950 April 4,350 May 4,950 June 4,650 July 5,250 August 4,850 September 5,350 October 5,650 November 6,250 December 5,950 a. Using linear regression analysis, what would you estimate demand to be for each month next year? Using a spreadsheet, follow the general format in Exhibit 3.8. (Do not round intermediate calculations. Round your answers to 2 decimal places.) b. To be reasonably confident of meeting demand, Nina decides to use 3 standard errors of estimate for safety.

- To illustrate these different approaches to Production Planning, identify to most appropriate Production Planning and Manufacturing approach the following industrial scenarios A company that manufactures tinned custard with predicted sales volumes of 6 million tins per yeararrow_forwardMary Jones and Jack Smart have joined forces to start M&J Food Products, a processor of packaged shredded lettuce for institutional use. Jack has years of food processing experience, and Mary has extensive commercial food preparation experience. The process will consist of opening crates of lettuce and then sorting, washing, slicing, preserving, and finally packaging the prepared lettuce. Together, with help from vendors, they think they can adequately estimate demand, fixed costs, revenues, and variable cost per 5-pound bag of lettuce. They think a largely manual process will have monthly fixed cost of $50,000 and a variable cost of $2.50 per bag. They expect to sell 75,000 bags of lettuce per month. They expect to sell the shredded lettuce for $3.25 per 5-pound bag. Jack and Mary has been contacted by a vendor to consider a more mechanized process. This new process will have monthly fixed cost of $125,000 per month with a variable cost of $1.75 per bag. Based on the above…arrow_forwardThe forecasted demand for fudge for the next four months is 110, 140, 230, and 160 pounds.
