7. What 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).

Defects per million operations

Lead time

Product demand

Fixed costs

9. Which of the following is one of the major types of stakeholders impacted by most consulting projects?

Board of directors

Other consultants

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

Minimize utilization

Minimize inventory of raw materials

Maximize inventory of working process

Maximize capacity

11. In contrast to TQM, what approach seeks radical change through innovation?

JIT distribution

Project management


Lean manufacturing

12. In 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?





The number of kanban card sets is the (Demand Average) x ( Lead Time) x (1 +Safety Stock as decimal) / (Container Size). 

Substituting values, (1,000 per hour x 10 hours) x(1 + .05) / 5 = 2,100 card sets

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

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

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

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

Factory that produces low volume, customized products

14. The basic notion of economies of scale assumes which of the following?

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

Total cost of output drops as volume increases

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

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

Reduce setup/changeover time

Eliminate some fixed costs

Improve capacity utilization

Build product in anticipation of demand

16. An advantage of a make to stock process is which of the following?

All units of output are unique

Rapid delivery of a standard product

It responds directly to customer orders

It allows the firm to avoid inventory costs

17. According to Little’s law, which of the following can be used to estimate inventory?

Set up time times throughput rate

Process velocity times flow time

Process time times cycle time

Throughput rate times flow time

18. Which of the following is a factor that causes a diseconomy of scale?

Increased utilization

Increased transportation costs

Increased total operating costs

19. If the run time for a batch of parts is 25 minutes on a machine, and the setup time is 75 minutes, which of the following is the operation time?

3 minutes

25 minutes

100 minutes

75 minutes

The operation time is the sum of the setup time and run time for a batch of parts, or 25minutes + 75 minutes = 100 minutes

20. Which of the following production process terms best describes the situation when activities in a stage of production must stop because there is no work?

Multiple stage processing
