The management of information is of great importance to operations management because: (a) without “information” one would have no knowledge of the state of input resources, process performance, or output goods and/or services; (b) properly developed information systems can contribute to the overall integration required to allow a firm to produce on a competitive basis; (c) “good” decisions require “good” information-?the right information, at the right place, at the right time. More specifically, the production planning problem can be described as the many effort to produce the right product in the right quantities in an efficient manner.

It should be Obvious then, that in order to address the first issue, i. E. , produce the right products in the right quantity, the companies need to have information about the market behavior, i. E. , the expected demand and any further developing trends. Similarly, in order to meet this expected demand efficiently, the companies need to have a clear understanding of – i. E. , detailed information about – their current operational status – i. E. , existing stock, production capacity, already initiated production, expected supplier deliveries, etc. Since only then they can make the right decisions regarding how to adjust the existing status in a way that will allow them to meet the expected demand in a cost-effective and timely fashion. 3.

Production Planning and Inventory Control (PICK) Schedules the manufacturing processes; manages inventory. Manufacturing Systems Applies the methodology, models, and the procedures Of mathematics or management information systems to manufacturing operations. This function might assume more importance in the home appliance market as manufacturers from outside the US. Provide increased competition. Process Engineering Design, develops, and evaluates production tools, equipment, and processes. Product Engineering Fine-tunes the product design to enhance production efficiency Maintenance

Focuses on designing systems and procedures and develops personnel who will create and maintain a reliable system, Supply Chain Management Determines the best sources for a given set of specifications, delivery, and price. Because the “home appliance” is a basic consumer good and competition occurs on parameters other than price, one might also find that the organization’s competitive strategy dictates that the operations function include the additional department. After Sale Service Responsible for the overall management and provision Of on-site and carry- in customer service.

In attempting to identify the departments of a ‘typical” manufacturer, one should recognize that the operations (not necessarily the department assignments) noted above are common to some degree among all manufacturers. The question is really to What degree, and the decision as to what degree is often based on competitive strategy in the marketplace rather than any “necessity” of prescribed organizational structure.

The number of stops per driver is certainly still a good productivity measure, since it gives a good idea regarding the “amount of service” provided by the company on a daily basis.

Another issue that could be tracked regarding the company’s productivity might be area covered per driver per day since this measure would provide additional information regarding the company’s capability to serve a more geographically dispersed area and its effectiveness with respect to the relevant route planning problems. 2. Since most call-in pickups are around 5. 00 p. M. , by offering some incentive, i. E. Discounted rates, to customers that call in earlier parts of the day, could help smoothen the experienced (service) demand, and reduce the congestion currently experienced by the company.

An additional De-congesting measure could be to processes most of the involved paperwork so that the expected service time at the customer site is minimized. 3. C. F. The Supplement to Chapter 10 on how to determine labor standards. Chapter 2 Operations Strategy in a Global Environment 1. There are three primary ways to achieve competitive advantage. Provide an example, not included in the text, for each of them. 1. Competing on Differentiation: i. Companies developing customized manufacturing equipment for other manufacturing companies ii. An airplane manufacturer like Boeing or Airbus iii. Ritz-Carlton 2.

Oil companies 3. Competing on Response i. Street salesmen selling umbrellas or anoraks during a storm ii. Business traveling services iii, Medical (emergency) services 2. Based on what you know about the automobile industry, how has the MM sweater of General Motors and Ford changed in the last 10-15 years? (a) Design Of goods and services: new products, designed and evaluated with CAD; coordinated with STEP (b)

Quality: 100% to standards; better feedback from customer benchmarking (c) Process and capacity planning: new gigs to improve quality new robots to reduce labor cost and improve quality (d) Location strategy: Location relative to suppliers is now more important, migration to low-cost labor areas (e) Layout strategy: Work cells, flexible assembly lines (t) Inventory management: MR., KIT are now regularly employed (g) Scheduling: Scheduling to meet requirements of KIT Expert systems and finite scheduling (h) Maintenance: Improved and increased training of maintenance personnel (i) Supply chain management:

Fewer suppliers who are more heavily integrated into the main organization’s information system 3. HOW does the MM strategy change during a product’s life cycle? During the introduction stage, the emphasis is on developing a product that is well accepted by the market, hence, issues such as product design and development are critical. During the growth stage, the emphasis shifts on establishing and maintaining a production process that is reliable and responsive to the developing demand as well as any further signals obtained from the market regarding the desired product quality.

At this stage also the major competitors will emerge, and therefore, the company must develop responding strategies to that will allow it to preserve, and if possible, increase its market share. During the product maturity phase, the market has stabilized in terms of product features, key competitors and market shares, in tact some overcapacity might have also been established, and therefore, the key concern for the companies is to preserve their market share by offering a reliable product at competitive prices. Hence, maintaining a stable and efficient production process is very important,

Finally, in the decline stage, priming the line to eliminate items not returning good margin becomes important, r-Geiger AS in your textbook provides a more detailed list of issues. 4. For vat reasons do domestic operations typically become international operations? Domestic firms become international because the world is changing, making competitors of not only other local firms, but non U. S. Firms as well. C. F. The relevant slide in (Powering) class presentation on the challenges and opportunities of globalization. 5.

Explain and give an example of how product design should be considered hen offering a product in a global market. Product design is important, as Coke recognizes, because tastes may differ from country to country. Other examples is the customization of the computer software to take into consideration the language differences at different countries, the design of the controls and the entire interior for cars produced for the Commonwealth countries where the steering wheel must be on the right side, etc. 6. What is the role of the World Trade Organization in modern global economy?

The World Trade Organization tries to lower trade barriers and ensure that international agreements and codes of conduct (including ethical standards) are uniformly applied around the world. “Its main function is to ensure that trade flows as smoothly, predictably, and freely as possible,” (From the WTFO web page, www. WTFO. Org). CASE STUDIES MINT-LUBE, INC. 1. (a) What constitutes the mission of Mint-Lube? TO provide economical preventive maintenance and interior auto cleaning, primarily to vehicles owned by individuals (as opposed to business), in the U. S. 2. (b) How does the Mint-Lube Strategy provide competitive advantage?

Mint-Lube’s approach to these 10 decisions includes: Product Design: A narrow product strategy could be defined as “lubricating automobiles” that allows the subsequent development of more focused and efficient operations (more in Chapter 5). Quality Strategy: Because of limited task variety, high repetition, good training, and good manuals, quality should be relatively easy to maintain. Process Strategy: The process strategy allows employees and capital investment to focus on doing this mission well, rather than trying to be a “general purpose” garage or gas station. Location Strategy: Facilities are usually located near residential areas.

Layout Strategy: The three bays are designed specifically for lubrication and vacuuming tasks to minimize wasted movement on the part of the employees and to contribute to the speedier service. Supply Chain Strategy: Purchasing is facilitated by negotiation of large purchases and custom packaging. Human Resources Strategy: Human resources strategy focuses on hiring a few employees with limited skills and training them in a limited number of tasks during the performance of which they can be closely supervised, Inventory: Inventory investment should be relatively low, and they should expect a high remover.

Scheduling: Scheduling is quite straightforward with similar times for most cars. Once volume and fluctuation in volume are determined, scheduling should be very direct-?assisting both staffing and customer relations. Maintenance: There is relative little equipment to be maintained, therefore little preventive maintenance required. With three bays and three systems, there is backup available in the case of failure. 3. Specialization of personnel and facilities should make Mint-Lube more efficient, Jobs/tasks accomplished per man hour would be a good place to start.
