________ represent an organization's attempt to gain increased efficiency through specialization, which can include, for example, concentrating on certain classes of customers.
Focused processes
What is the link between focused processes and specialization? What kinds of focus are possible?
Focused processes are a means of obtaining increased productivity through forms of specialization. Focus can take several forms, including concentrating on specific classes of customers, working only with products in selected product families, specializing in a specific service, or working with a narrow range of technology.
In an affluent society, how do we produce a wide number of options for products at low cost? Hint: Focus on how to address some of the major challenges of mass customization.
For mass customization, products should be built-to-order. Product design must be imaginative. Process design must be flexible and able to accommodate changes in both design and technology. Inventory management requires tight control. Tight schedules are needed that track orders and material from design through delivery. Responsive partners in the supply chain can yield effective collaboration.
What is mass customization?
Mass customization is rapid, low-cost production of goods and services that fulfill increasingly unique customer desires. It brings us the variety of products traditionally provided by the process focus, with low costs associated with standardized high volume production (the product focus).
Identify the four basic process strategies, and describe them in a complete sentence or two each.
Process focus is a job shop—high variety and low volume; repetitive focus is an assembly line—relatively standardized products with options from modules; product focus is for high volume, low-variety, products, such as oil refining and flour milling; and mass customization is for high volume, high variety.
________ is the fundamental rethinking of business processes to bring about dramatic improvements in performance.

Time-function mapping is a flowchart with time added to the horizontal axis.
TRUE
When selecting new equipment and technology, decision makers look for flexibility—the ability to respond with little penalty in time, cost, or customer value.
TRUE
Provide an example of the postponement strategy for improving service productivity.
The postponement strategy refers to customizing the product at delivery, not at production. Examples will vary, but a home builder might leave some tasks unfinished until the house is sold, so that the buyer can make those final decisions. Carpeting, paint colors, cabinet doors, and some appliance choices might be good examples. Another example would be cars or vans.
Identify the techniques for improving service productivity. For any two techniques, describe in a short paragraph, and include an example.
The seven techniques are separation, self-service, postponement, focus, modules, automation, scheduling, and training. • Separation: structuring the service such that the customer must go where the service is offered (a medical facility) • Self-service: let customers perform their own comparisons (supermarket shopping) • Postponement: customizing at time of delivery or in the final stages of the process (dealer-installed versus factory-installed options on automobiles, boats, etc.; Wendy's Hamburgers) • Focus: restricting the product offerings, options, or degree of customization allowed (limited number of factory installed options on a new automobile) • Modules: services selected from modular choices (health insurance programs) • Automation: separating services that may lend themselves to automation (automatic teller machines) • Scheduling: precise personnel scheduling (keep close watch on how many checkout lanes are needed) • Training: clarifying options, teaching problem avoidance (after-sale maintenance personnel, counselors)
Which of the following is TRUE regarding vision systems? A) They are consistently accurate. B) They are modest in cost. C) They do not become bored. D) All of the above are true. E) None of the above is true.
