    Advantages Disadvantages
    Staff can be trained gradually as they only need to train in the part of the system that is currently being phased in. More expensive than direct changeover as you have to test each phase separately before moving onto the next.

    Why parallel installation is expensive?

    Disadvantages. The cost of implementation is very expensive because of the need to operate the two systems at the same time. This would be prohibitive with a large and complex system. Parallel running implementation also requires a lot of time and needs frequent maintenance.
