Answer 5

True

Question 6

True or False: Data conversion is easier when a new system replaces a manual system because all data can be entered manually, unless it must be scanned.

Answer 6

False. Data conversion is more difficult when the new system replaces a manual system, because all data must be entered manually unless it can be scanned.

Question 7

True or False: To minimize the need to require information from two different systems, cyclical information systems usually are converted using the direct cutover method at the beginning of a quarter, calendar year, or fiscal year.

Answer 7

True

Question 8

True or False: Phased operation is more expensive than full parallel operation because the analyst has to work with the entire system at any given time.

Answer 8

False. Phased operation is less expensive than full parallel operation because the analyst has to work with only one part of the system at a time.

Question 9

True or False: The post-implementation evaluation of a system verifies that the new system meets specified requirements, complies with user objectives, and produces the anticipated benefits.

Answer 9

True

Question 10

True or False: Modules that are independent are tightly coupled.

Answer 10

False. Modules that are independent are loosely coupled.

Answer 12

True

Question 13

True or False: Pseudocode is a technique for representing program logic.

Answer 13

True

Question 14

True or False: Critics of agile development often claim that because it focuses on quick iterations and fast releases, it lacks discipline and produces systems of questionable quality.

Answer 14

True

Question 15

True or False: Test data should contain only correct data.

Answer 15

False. Test data should contain both correct data and erroneous data and should test all possible situations that could occur.

Question 16

True or False: Program documentation describes the system’s functions and how they are implemented.

Answer 16

False. System documentation describes the system’s functions and how they are implemented.
