CONVERSION STRATIGIES

                                                CONVERSION STRATEGIES 

 

Conversion means switch on to a new system from an existing system. It is not always true that existing system caters the needs of persons interacting with this or we can say that sometimes these systems become outdated. As we have discussed that Capricornia Car Pool system now needs to be modified.

As it is suggested that new system should be computerized it is obvious that it needs implementation of new enterprise system. As there are many conversion  strategies each of which is having its own pros and cons.

Major conversion strategies are as follows;

 

1 Direct Cut Over

2 Parallel Method

3 Pilot Method

4 Phased Method

 

A. Direct Cut Over

In this method on a particular day new system is immediately replaced with new system in whole organization .

ADVANTAGES ;

1 It costs a less amount of money as everything has to just set up for once.

2 It is very easy to make change over .

 

DISADVANTAGES:

1 It is more risky because it is not always that implementation of systems is successful. If there is any problem in the system then organization as a whole has to suffer.

2  It is very difficult to detect minor errors  as due to absence of parallel system. Errors may be there because testing data is not as big as there may be live data.

3 Sometimes major errors can terminate the system so whole operation will be stopped and there will be difficulty of back up.

 

But in some systems it is mandatory to have a direct cut over because sometimes operating conditions can only support a single system.

 

B. Parallel Method

It is the method in which existing system and new systems are made to run or work simultaneously or in parallel direction.

 

ADVANTAGES:

1 With the help of this even minor errors can be detected.

2  There is no risk if there does not occurs successful implementation of new system.

 

 

DISADVANTAGES:

 

1 It is very expensive conversion strategy as two systems has to run at the same time so it is a great expense in terms of power and support.

2 There is always a lot of wastage of money and time.

C  PILOT METHOD

 It is the method in which new system is implemented in a single branch or department to have exact output from the system. This method is very useful for the companies having multi locations.

ADVANTAGES:

1.It is an economic conversion strategy.

2 It reduces the risk.

 

DISADVANTAGES:

  1. Sometimes some operations remains untested.

 

 

D PHASED METHOD 

It is the method in which a part of system is build to for all users. It replaces the old system in stages.

 

ADVANTAGES:

1 There is a negligible chance of any type of problem in the system as it is tested on every stage.

2 It seems more user friendly.

 

DISADVANTAGES:

1 It needs a lot of time for full implementation of system.

 

 

As CQU is having many campuses at different locations so Pilot conversion strategy will prove very beneficial for the organization.
