f. %he use of previously written software resources+ especially objects and components+ in

new application.

days in a series of intensive meetings to specify or review system requirements.

h. !n iterative process of systems development in which requirements are converted to aworking system that is continually revised through close work between an analyst and

users.

rototyping

i. %he part of the design phase of the S"&' in which all functional features of the systemchosen for development in analysis are described independent of any computer platform.

&ogical design

j. %he part of the design phase of the S"&' in which the logical specifications of the

system from logical design are transformed into technologyspecific details from which

all programming and system constructions can be accomplished.

hysical design

k. %he practice of turning over responsibility of some to all of an organi)ation/s information

systems applications and operations to an outside firm.

four phases of development+ each of which is organi)ed into a number of separate

iterations+ inception+ elaboration+ construction and transition.

4. *n the section on choosing offtheshelf software+ eight criteria are proposed for evaluating

alternative packages. Suppose the choice was between alternative custom software

developers rather than prewritten packages. 5hat criteria would be appropriate to select and

compare among competing bidders for custom development of an application6 "efine eachof these criteria.

7. 5hy is it important to use systems analysis and design methodologies when building a

system6 5hy not just build the system in whatever way seems to be 8quick and easy96
