test2-essay:question 2(8/9/09)

the process of developing a new system will have to follow a strict order of a cycle called the system development cycle.there are five phases in how to develop a new system.first, planning the proposal.we need to plan first what is the users' requirement, the feasibility of the system will be tested and the products want to be developed.the right proposal can build a good system.

for the second phase is analyzing.we have to analyze the proposal or plan that we have made.the system will be analyzed whether it is useful or not.this is to avoid the system from having any problem.

and the third one is designing.after analyzing the system, we can design the system according to the suitability of system.this will make the user to recognize the system easily.

then for the fourth phase is implementation.for the implementation phase, they will install and try the new programs.this program is also will train the users when using it.then they can develop into the new program.

for the last one is operating,supporting and security.the system will be operated and supported by any other programs so that they can be used.then, the system will be included with security so that the users can use it safely.

Feasibility means measure of how suitable system development will be to the company.there are four tests to evaluate feasibility which is operational feasibility,schedule feasibility,technical feasibility and economic feasibility which is also called cost or benefit feasibility.

the final activity in the implementation phase is to convert the old system to the new one.this change can take place using one or more conversion strategies.first is direct conversion.this conversion change the old system to the new system alternating.so this will be no confusion for the users to convert it.the other conversion is parallel conversion.this conversion is using both of old and new system in the same time.this make the users can make check and balance.for the phased conversion it is using one system in one time.for this the feasibility has not been tested.and the last conversion is called pilot conversion.in this conversion they use both of the system differently.for the users they cannot identified which is the best system.between all of the conversion strategies,whether it is good or not it is in the users' choice to choose the best one.
