a. direct conversion b. parallel conversion c. phased-in conversion d. None of the options is correct
solution :-
Direct conversion - In this kind of conversion old systems are stop and new systems used , but here a proper testing must be done before implementation of new system to avoid risks, errors etc for smooth functioning.
Parallel conversion - Here both old systems and new systems used parallel till the time new systems gained the same level with proper and effective implenetation . Here cost is high but there is no risk and errors can be easily modified.
Phased In Conversion - Here users are instructed to use the new system gradually and a step by step care for effective implementation of the new system. Here costs are less and users can easily adopt the new system without any break down of time .
So after analysis , here we can see that Phased In conversion is the best conversion means so, the option no ( c) with Phased In Conversion is the correct answer
