9626 Chap15 System Life Cycle

During Evaluation stage, the most important question to be ask the user is .....

• whether the new system meets the user requirements

• Whether the old system meets the user requirements

• Whether they are using the new system ore not

• None of the above.

There are four types of maintenance. There are .....

• Perfective, Preventative, Adaptive and Corrective

• Parallel, Phase, Pilot and Direct

• Beta, Alpha, White box and Black box

• Normal, Abnormal, Extreme, Live

User documentation is a user guide giving instructions to the user. The main part of the user guide is ........

• Listing of all the files used in the system and their their purposed identified.

• Number of users in the organization

• How critical the system is to the running of the organization.

• Cost

• The programmers are not prepared.

One of the disadvantage of this installation method is duplication of data input where additional staffing is needed to enter data. In which installation method is this situation referring to.

• Direct

• Parallel

• Pilot

• Phased

One of the disadvantage of this installation method is that all the staff need to be trained in advance of changeover and this might lead to the users forgetting what they have learned by the time they start to use the new system. In which installation method is this situation referring to.

• Parallel

• Pilot

• Phased

• Direct

• the expected result

• Who will enter the data

• None (blank)

• Data Dictionaries

• Test Plan

• Normalization process

• DFD

"Show the processes that take place within the system and the decision that are made. It focuses on the logic of the system and not the data within the system." This statement is referring to a ................

• Data Dictionaries

• DFD

• System Flowchart

• Black box testing
