Cut over, Parallel System and Trial system

(1/1)

methodsboy:
^someone please describe what they are  ???
Also : Why should an audit of the system take place, and what might this involve?
thnx

ell:
I believe cut-over refers to the implementation stage and the changeover/conversion methods. Changeover/conversion methods are ways of converting an old system to a new system. I'll list and briefly describe the ones you need to know for SD:

DirectThe old system is completely scrapped and the new one is implemented immediatelyPhasedThe new system is gradually implemented over a period of time (i.e. component by component)ParallelThe old and new system are run simultaneously until the new system is ready for use.Pilot (trial)Instead of implementing the new system throughout the whole organisation, it is only implemented within one section or department.
