FALSE Operations, marketing and finance are naturally dependent upon one another

11. Assembly lines achieved productivity but at the expense of standard of living.

FALSE Productivity and standard of living go hand in hand.

7. Service operations require additional inventory because of the unpredictability of consumer demand.

FALSE Service operations cannot use inventory as a hedge against unpredictable demand.

14. 'Value added' by definition is always a positive number since 'added' implies increases.

FALSE Some transformations result in the output being worth less than the inputs.

17. Special-purpose technology is a common way of offering increased customization in manufacturing or services without taking on additional labor costs.

FALSE Special-purpose technology typically reduces costs through standardization.

13. The word "technology" is used only to refer to "information technology".

FALSE Technology also refers to the technology involved in resource transformations.

12. The operations manager has primary responsibility for making operations system design decisions, such as system capacity and location of facilities.
