Why the company should carry out parallel running of the two systems
Parallel running refers to the running of the existing system and the new system concurrently for a period of time before switching to the new account. This is carried out for the following reasons:
– It enables the programmers and the users to review the system, prior to authorisation for full implementation;
– Implementing smooth personal changes and avoiding the problem that key employees might take with them all the knowledge on how the system works.
– Parallel running assists in training the staff on how to operate the system while still having the old system to refer to;
– It helps in testing the system to ensure that the system is fully operational before putting it into full use.
