1What is the term that refers to “the fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in critical, contemporary measures of performance, such as cost, quality, service, and speed” (as cited in Jacobs & Chase, 2011, p. 461).

TQM

 

Continuous improvement

 

Reengineering

 

Operations consulting process

2Which of the following operations consulting tools provide summary performance updates for specific processes and are generally presented in graphical form with color-coding of trend lines and alarms?

 

Decision trees

 

Stakeholder analysis

 

Responsibility charts

 

Process dashboards

3An advantage of a make-to-stock process is which of the following?

 

All units of output are unique

 

It allows the firm to avoid inventory costs

 

It responds directly to customer orders

 

Rapid delivery of a standard product

4Which of the following is a principle of reengineering?

 

Organize around the tasks

 

Capture information many times, at the source and where it is interpreted

 

Integrate the outcomes of parallel activities

 

Treat geographically dispersed resources as though they were centralized

5Which of the following is a situation that likely will yield economies of scale?

 

Factory that fully utilizes dedicated resources for information technology, material handling, and administrative support

 

Large factory with dedicated capacity that is able to produce twice the number of units as locally demanded

 

Company with factories in multiple countries that produces products for local demand

 

Factory that produces low volume, customized products

6Lean production seeks to achieve high volume production using which of the following?

 

Minimize utilization

 

Minimize inventory of raw materials

 

Maximize inventory of work-in-process

 

Maximize capacity

7The basic notion of economies of scale assumes which of the following?

 

Total cost of output drops as volume increases

 

A piece of equipment with twice the capacity of another piece typically costs twice as much to purchase and to operate

 

Average cost per unit of output drops as a plant gets larger and volume increases

 

Two plants can be operated at the same cost as a single plant

8In setting up a kanban control system, you need to determine the number of kanban card sets needed. If the average number of units demanded is 1,000 per hour, the lead time to replenish the order for this item is 10 hours, the container size is 5 units, and the safety stock is estimated to be 5% of the expected demand, what is the number of kanban card sets needed?

 

440

 

210

 

1,050

 

2,100

9Which of the following are possible examples of cycle times?

 

Time required to produce a batch of parts

 

Time that a part waits in queue

 

Time it takes for an instructor to grade an exam

 

Time to set up a new assembly line

10Which of the following terms refers to a special type of flowcharting tool that is valuable for the development of lean processes?

 

Value stream mapping

 

Kaizen

 

JIT production

 

Kanban production control system

11To implement a flow process in developing a lean system, a firm might do which of the following?

Improve capacity utilization

 

Reduce setup/changeover time

 

Eliminate some fixed costs

12In the pull system, which of the following is the partner that begins the process of pulling?

 

Vendors
