Essentials of System Analysis and Design, 4e (Valacich)
Chapter 1 The Systems Development Environment

1) The end user is not the person in the organization most involved in the systems analysis and design process. Answer: TRUE
Diff: 2Page Ref: 3

2) Systems analysis is the second phase of the systems development life cycle. Answer: TRUE
Diff: 2Page Ref: 3

3) The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently. Answer: TRUE

Diff: 2Page Ref: 4

4) Components are parts, or aggregation of parts of the system. Answer: TRUE
Diff: 1Page Ref: 7

5) A boundary is the point of contact where a system meets its environment or where subsystems meet each other. Answer: FALSE
Diff: 2Page Ref: 7

6) An information system interacts with its environment when it processes data. Answer: FALSE
Diff: 2Page Ref: 7

7) An interface separates a system from other systems.
Answer: FALSE
Diff: 2Page Ref: 7

8) A system's environment is everything outside a system's boundary that influences the system. Answer: TRUE
Diff: 1Page Ref: 7

9) Interfaces exist between subsystems.
Answer: TRUE
Diff: 1Page Ref: 7

10) A system's capacity can be viewed as a system constraint. Answer: TRUE
Diff: 2Page Ref: 7

11) Cohesion is the process of breaking down a system into its smaller components. Answer: FALSE
Diff: 2Page Ref: 7

12) Coupling results in smaller and less complex systems that are easier to understand than larger, complicated systems. Answer: FALSE
Diff: 3Page Ref: 8

13) Decomposition allows the systems analyst to build different parts of the system at independent times and have the help of different analysts. Answer: TRUE
Diff: 2Page Ref: 8

14) Component focusing allows the systems analyst to break a system into small, manageable, and understandable subsystems. Answer: FALSE
Diff: 2Page Ref: 8

15) Modularity is a direct result of decomposition.
Answer: TRUE
Diff: 1Page Ref: 9

16) Modularity divides a system into chunks or modules of a relatively uniform size. Answer: TRUE
Diff: 2Page Ref: 9

17) Cohesion is the extent to which subsystems depend on each other. Answer: FALSE
Diff: 2Page Ref: 10

18) Client machines are the PCs you use at your desk at work. Answer: TRUE
Diff: 1Page Ref: 10

19) Enterprise-wide systems are large, complex systems that consist of a series of independent system modules. Answer: TRUE
Diff: 2Page Ref: 10

20) Systems analysts are key to the systems development process. Answer: TRUE
Diff: 1Page Ref: 11

21) The major focus of transaction processing systems (TPS) is capturing transaction data, which is then sent to a computerized database of all transactions. Answer: TRUE
Diff: 2Page Ref: 12

22) Transaction processing systems (TPS) take raw data available in a data warehouse and convert them into a meaningful aggregate form. Answer: FALSE
Diff: 2Page Ref: 13

23) A decision support system (DSS) uses knowledge gathered from experts to make recommendations to managers. Answer: FALSE
Diff: 2Page Ref: 14

24) The systems development method associated with a decision support system is concerned with capturing, validating, and storing data and with moving data between each required step. Answer: FALSE

Diff: 3Page Ref: 15

25) The systems development method associated with a management information system is concerned with understanding relationships between data so data can be accessed and summarized in a variety of ways. Answer: TRUE

Diff: 3Page Ref: 15

26) A systems development methodology is a standard process followed in an organization to conduct all the steps necessary to analyze, design, implement, and maintain information systems. Answer: TRUE

Diff: 2Page Ref: 15

27) A systems development technique is the series of steps used to mark the...
