Part II

Multiple Choice

for developing your information system?

b) Planning

c) Design

d) Analysis

22. If you the end user participated on a team responsible for defining a

prototype for a proposed application, what phase in the SDLC would you be

working in?

a) Analysis

b) Design

c) Planning

d) Development

23. What is the difference between the design phase and the analysis phase?

a) The analysis phase follows the design phase and examines the requirements

developed during the design phase

b) The design phase creates the code from the logical requirements developed

in the analysis phase

c) Analysis and design belong to the same phase and create an iterative

process between the two activities

d) The design phase takes the requirements developed in the analysis phase

and creates a design from them

24. What is the difference between the implementation phase and the maintenance

phase?

needed to meet existing business goals

working properly; the implementation phase makes minor adjustments when

needed to meet new business goals

30. What is a common test that is performed to ensure the quality of the

information system you are building?

a) Unit and system testing

b) User acceptance testing

to run, what type of implementation method would you be following?

a) Pilot implementation

b) Phase implementation

c) Parallel implementation
