Chapter Overview

Chapter 6 provides an overview of cost and its importance to profitability and operations decisions. Cost has a significant impact on value in two ways. First, price is also dependent on costs, and price contributes to a customer's perception of value, cost affects demand by its impact on the way customers view value relative to competitors.  Second, in determining net income, costs of goods sold are subtracted. the greater the costs, the lower the net income. Increasing costs result in the reduction of net income and the corresponding reduction in profitability.

Businesses frequently seek to increase productivity, and that often falls within the charges of the operations function. Productivity measures are created as a ratio of outputs to inputs. Inputs include costs. As costs go up, productivity goes down.

OM in Action 

OM in Action 6.1 Price is the critical factor in purchasing decisions for "commodity" type products. Commodities are products that are standardized and producers have no real way to differentiate themselves other than with price.  Web sites, known as shopping bots, provide services for these types of items to help potential purchasers identify the low price producer. Visit Pricewatch to see how this process works. Compare the Pricewatch service to that of NexTag.

a. What are your reactions to the Pricewatch site? 
b. Would you use the Pricewatch service the next time you need to purchase computer-related products? Why or why not?
c.  How does Pricewatch compare to NexTag? Which would you use? Why?

OM in Action 6.2  Price competition is critical for typical consumer products as well as computer peripherals. bSilly, for example is a shopping bot just for kids' products.  Streetprices provides shopping bot services for computers and other  electronics.  Try out bSilly or Streetprices by searching for the lowest price on a product of interest to you.

Putting It All Together:  Virtual Case Studies 

Putting It all Together 6.1:  In Ford: Why It's Worse Than You Think, (Business Week, June 25, 2001), several of Ford's quality and productivity problems are discussed. The chairman of Ford briefly mentions some of these problems in his letter to the shareholders in the 2000 annual report.

a.
What were Ford's alternatives? Was the recall Ford's only real option or were other alternatives available? 
b. Do you think Ford selected the low cost alternative? Why or why not?
Putting It all Together 6.2: Comparing Contract Manufacturing Services The concept of an "electronics manufacturing service" (EMS) didn't exist prior to the late 1990's. Many firms are motivated to outsource manufacturing, particularly when changing technology can make a component obsolete in mere months. The Barons of Outsourcing, (Business Week, August 28,2000) and The Chips are Down. Way Down (Business Week, August 7, 2000), provide perspectives on this trend from two distinctly different segments of the electronics industry.  Two key players in the in the broader electronics manufacturing arena are Flextronics and Solectron . In the more narrow chip design and production arena, key players include Taiwan Semiconductor Manufacturing Corp. and United Microelectronics Corp.  Select one pair of competitors in the same arena and explore the website for each firm.

a. 
How do the firms in each pair compare?  What capabilities do they offer? Do they each have distinctive advantages over the other? What are they? 
b. Who are the major customers of each? Does the customer list overlap? How do the costumers differ? What are the customer characteristics? Do the needs of the customers appear to match the capabilities of the supplier?
c. Summarize the strengths and weaknesses of each supplier.

Business processes produce value, but can also produce a significant amount of waste. Reducing costs by eliminating waste is almost impossible without the collection of specific information related to those processes.  Collecting relevant data can often lead to cost reductions.
