Chapter Overview 

Chapter 8 is devoted to the topic of timeliness.  Response time, in any aspect of business, translates directly into money.  Shorter times result in quicker financial returns, increasing ROA and profitability.  In addition, many quality attributes associated with service are time-based.  Reducing the time required for resources to process products or customers increases capacity and generates more revenue.  Reduce time means reduced costs for the business and increased value for the B2B and B2C customer.

Esources 

Esource 8.1  Response time for Internet-based businesses is just as important as a quick response time for any other business.  When the competition is just a click away, many customers are not willing to wait more than a few seconds for a download. Unfortunately, download times can be affected by Internet traffic world wide.  The Internet Traffic Report monitors Internet traffic worldwide and provides up-to-date data. Check out the 24-hour and 7-day graphs to view the patterns.
Esource   8.2 Consumers often view response time as the most important aspect of customer service.  An easy way to view how important this is is to view the customer evaluations of a large business on Ebay.  Check out the feedback of an Ebay seller to find out how important the customer service, and particularly quick response, is to buyers.  If you're unfamiliar, go to Ebay, select any category of interest, and then select an item of interest.  Click on the number in parentheses next to the seller's name. That number is the quantity of buyer feedback messages that have been submitted.  It links directly to the actual feedback messages submitted by sellers.  For an alternative perspective, click on a seller feedback number to view the type of feedback submitted by buyers. Once again, response time is high on their list of priorities.
Esource 8.3  When idled because of maintenance problems, expensive resources immediately stop generating a financial return. Their costs continue, however.  The airlines provide an excellent example of companies with huge investments in equipment that needs to remain productive. In the past few years General Electric has invested much effort into the development of services to minimize these impacts.  One branch, GE Aircraft Engines On Wing Support, provides aircraft engine service anywhere in the world.  Check out the On Wing Support website and the description of their products and services.  

Reel Operations Video Clips 

Reel Operations Video  8.1 In United Airlines: Scheduling Complex Resources in a Service , we get a glimpse at not only how complex scheduling can be for resources that depend on each other, but also how important effective scheduling is for profitability.
Reel Operations Video  8.2 Large projects are notoriously difficult to schedule. Those that depend on cooperation from weather conditions are even more likely to incur delays than most. In Complex Projects Almost Always Bring Surprises: The Alton Bridge Project, we get an overview of the successes and failures associated with a very complex project.

Interactive Models 

Interactive Model 8.1
Sequencing Rules Interactive Model
The Sequencing Rules Interactive Model provides four sequencing methods (FCFS, SPT, EDD, and Critical Ratio) for sequencing orders. The user selects the sequencing rule from the pull-down list and observes immediate feedback in the form of a Gantt Chart. 
Interactive  Model 8.2 Waiting Line Interactive Model 
The Waiting Line Interactive Model provides a simulation of a waiting line environment. The waiting line system can be configured as a single or double phase system, with up to 4 servers in each phase.  Varying the waiting line configuration, the arrival rate, and the service rate allows for experimentation with a variety of waiting line scenarios.

Supplementary Readings 

Supplementary Reading 8.1 The ability to compress the "time to market" cycle has tremendous impact on the return of financial investments. In "Oxford Automotive: Go Fast Strategy in Action", Automotive Design and Production, the advantages of bringing a new automotive supplier's factory on line in a short period of time is discussed.
Supplementary 
Reading 8.2
No discussion of timeliness could fail to at least acknowledge the impact of just-in-time (JIT) management, which is covered extensively in Chapter 15.  Read "Just-in-time Manufacturing is Working Overtime," Business Week, 11/8/99. Just-in-time (JIT) management is an approach used to eliminate waste, including inventory waste, process waste, wasted labor, and waste resulting from poor quality.  It strives to reduce inventory levels to the leanest possible amounts and has seen great benefits, but there are risks as well.  This article provides a view of the potential profitability downside of JIT which can result from time-related costs of implementing JIT.

Reading 8.3
ROI: Using Technology to Buy Time (iSource, December 2001) describes how short delays in the development of new products in the semiconductor industry translate into millions of dollars in lost profit.

Online Business Tour

Online Business Tour 8.1 In many businesses, an important aspect of quality is speed. For services, the faster the customer can get what they want, the better. Retailers must balance speed and convenience with a desire to keep customers in the store so that they may see and buy more products.  Kohl's department stores are organized in a unique way, in hopes of adding value to the customer's experience.
a.  Low price plays a major role in determining the value of Kohl's products, but the shopper's experience also contributes.  Compare the organization of Kohl's to other department stores you have experienced. How does Kohl's differ? How does the difference affect timeliness?
b. Do you think Kohl's design, which reduces the time a customer must spend in the store, reduces sales? Explain

Letters from the Top 

Letter from the Top 8.1 Timeliness doesn't only mean speeding up the response to customers. It also means that companies must be able to quickly react to changing conditions in their markets and changing environmental pressures. Read Nike CEO Philip H. Knight's 2001 letter to shareholders.

b. Why, based on Knight's letter, has Nike had difficulty responding quickly to changing conditions? Does his plan to correct the situation make sense to you? What changes would you suggest?
