...Managing Operations is Sound Prioritization: The Mexicana Wire Works Case A case report presented to the faculty of the Master of Business Administration Far Eastern University In partial fulfilment of the requirements In Quantitative Analysis Submitted To: Professor Willy Cuason Submitted By: Jeancy Dela Rosa Joan Eclipse Gerra Lanuza Mark Nimeno Timmyleh Pocong Jerome Tumambing June 03, 2014 I. Case Background Mexicana Wire Winding, Inc. is a subsidiary of Westover Wire Works based in Texas which is a medium-sized producer of wire windings of electrical transformers. Ron Garcia is the new management trainee, who studied operations management in his MBA program but lacks any technical knowledge about the manufacturing process. He is tasked to help the company in solving the increase in booking orders for April.There will be new equipments coming in the next several months but these won‘t help them fill the April orders. (Render & Stair, 2012) To better understand the case the group researched on the sequence on how to produce wire windings as discussed in the case: 1. “Wire Winding- the metalworking process used to reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing die(s). There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips...

...Case Study Mexicana Wire Works Ron Garcia felt good about his first week as a management trainee at Mexicana Wire Winding, Inc. He had not yet developed any technical knowledge about the manufacturing process, but he had toured the entire facility, located in the suburbs of Mexico City, and had met many people in various areas of the operation. Mexicana, a subsidiary of Westover Wire Works, a Texas firm, is a medium-sized producer of wire windings used in making electrical transformers. Carlos Alverez, the production control manager, described the windings to Garcia as being of standardized design. Garcia’s tour of the plant, laid out by process type (see Figure 7.20), followed the manufacturing sequence for the windings: drawing, extrusion, winding, inspection, and packaging. After inspection, good product is packaged and sent to finished product storage; defective product is stored separately until it can be reworked. On March 8, Vivian Espania, Mexicana’s general manager, stopped by Garcia’s office and asked him to attend a staff meeting at 1:00 P.M. “Let’s get started with the business at hand,” Vivian said, opening the meeting. “You all have met Ron Garcia, our new management trainee. Ron studied operations management in his MBA program in southern California, so I think he is competent to help us with a problem we have been discussing for a long time without resolution. I’m sure that each of you on my staff will give Ron your full cooperation.” Vivian turned...

...Hi Nika, Just like in any quantitative analysis approach, LP (Linear Programming) aids the decision making process of manufacturing businesses like Mexicana wire works. Our solution will help them create the right product mix that will maximize their profit. Both group recommends that for the month of April, Mexicana should manufacture 1100 units of W0075C (300 units backorder), 250 units of W0033C (no backorder), no W0005X (1510 units backorder) and 600 units of W0007X (516 units of backorder) to realize a maximum profit of $59,900. In a way it answered the problem of Jose Arroyo, production control manager of figuring out which order to run and which to back order. However, it still did not answer the bigger problem of matching the demand with the supply. As group 6 said they should be Honoring commitment to customers. Ensuring this is beyond the scope of LP. They should be looking into other solutions such as letting their marketing department negotiate with the customers to lower the number of what was agreed upon or they should take into consideration tying up with partners just to meet the committed number of wires. This is to avoid dissatisfied customers and legal compliations. Let us also take into consideration that Ron Garcia is very new to the company. Although he has toured the entire facility and has met many people in various areas of the operation he does not still know the ins and outs of their company. He is also basing his recommendations on the data...

...Case Study 4.1 Background Ron Garcia, a management trainee at Mexicana Wire Winding, Inc. has been asked by the general manager to conduct an analysis seeking maximum profit under current production constraints. The company is seeking a banner year to obtain leverage for refinancing long-term debt (Render et al, 2012, p. 300). Using linear programming, we can assess the max profit potential while taking into account a series of identified constraints. Mexicana Wireworks Max Profit Analysis Overall production constraints are laid out in Fig 1.1 and include product max profit capability, April orders/Demand, key customer fills promised by the General Manager, labor requirements for each product, and maximum Hours capacity of the Plant (Render et al, 2012, p. 301). Product Profit was determined by subtracting overall costs (material, labor, overhead) from selling price. Average output per month is only 2400 units, 850 of which are rejected for winding errors, well below capacity to meet April’s customer demand. The focus in this analysis consists of the key customer demand promised by the GM and maximum profits under constraints of plant capacity. Max profit=34X1 + 30X2 + 60X3 + 25X4. After plugging numbers into the QM software, the results are: W0075C = 1100 units (>= 150) W0033C = 250 units W0005X = 0 units W0007X = 600 units (>=600) Optimum Profit = US $59900 Packaging hours become the limiting factor as far as plant capacity is concerned, wasting potential...

Case study 1 Mexicana Wire Works Page 306-307 Case study 2 Custom Vans, Inc. Custom Vans, Inc., specializes in converting standard vans into campers. Depending on the amount of work and customizing to be done, the customizing could cost less than $1,000 to more than $5,000. In less than four years, Tony Rizzo was able to expand his small operation in Gary, Indiana, to other major outlets in Chicago, Milwaukee, Minneapolis, and Detroit. Innovation was the major factor in Tony’s success in converting a small van shop into one of the largest and most profitable custom van operations in the Midwest. Tony seemed to have a special ability to design and develop unique features and devices that were always in high demand by van owners. An example was Shower-Rific, which was developed by Tony only six months after Custom Vans, Inc., was started. These small showers were completely self-contained, and they could be placed in almost any type of van and in a number of different locations within a van. Shower-Rific was made of fiberglass and contained towel racks, built-in soap and shampoo holders, and a unique plastic door. Each Shower-Rific took 2 gallons of fiberglass and 3 hours of labor to manufacture. Most...

...ASSESSING THE POWER OF PORTER'S DIAMOND MODEL IN THE AUTOMOBILE INDUSTRY IN MEXICO AFTER TEN YEARS OF NAFTA SALVADOR BARRAGAN Master in Business Administration, IPADE Business School, 1996 BSc in Industrial Engineering, Universidad Panamericana, 1994 A Research Project Submitted to the School of Graduate Studies of the University of Lethbridge in Partial Fulfilment of the Requirements for the Degree MASTER OF SCIENCE IN MANAGEMENT Faculty of Management University of Lethbridge LETHBRIDGE, ALBERTA, CANADA © Salvador Barragán, 2005 ii Abstract It has been ten years since the signature of the NAFTA agreement among Canada, U.S., and Mexico. For Mexico, this was a decisive step away from a protectionism model toward a free trade market. One of the main purposes for Mexico in joining NAFTA was to increase the competitiveness of its manufacturing sector, especially the automotive industry. In this paper, Porter’s Diamond Model of national competitiveness and some critiques that attempt to extend the usefulness of the model are analyzed. The Doubled Diamond and the role of MNEs in a host country are both examined through a case study research of the foreign-owned automobile industry in Mexico. The findings of this study show evidence of a broader role of MNEs than in the original framework, as well as the usefulness of the doubled diamond extension to explain alternative sources of competitiveness in early stages of development. iii Acknowledgments...

...9-707-445 REV: AUGUST 25, 2008 JORDAN SIEGEL Lincoln Electric Introduction John Stropki, CEO of Lincoln Electric, returned home from Mumbai to company headquarters in Cleveland, having sampled the local Maharashtran delicacies while studying opportunities in the Indian market. From his vantage point in 2006, Stropki looked back on his company’s more than 100 years in the welding equipment and consumables industry with pride, wondering whether a strong push into India should be the next step in his company’s globalization. An India expansion had been considered for several years, but thus far the company had focused on growing its operations in China and elsewhere around the globe. If Stropki were to approve a significant allocation of resources toward an India expansion, he wondered what would be the best way to enter. He had a wealth of company lessons and experiences to apply to the India investment decision, as his company had had international operations since the 1940s, had struggled internationally in the late 1980s and early 1990s, and had gone on to regain its global competitive advantage in the late 1990s and early 2000s. During Stropki’s tenure as CEO since 2004, the company had further expanded globally and by 2006 owned manufacturing operations in 19 countries across five continents. Most recently, the company had enjoyed increasing success in China as a result of its aggressive expansion through both a joint venture and set of majority-owned...
