Parallel Implementation

A parallel implementation or approach implies that a new solution is implemented parallel to the current operational system in use. Those who are using the system will not see major downtime once it is implemented. The trick here is to implement the system. Once the new solution is tested and up and running, it is "switched" on and the older version is "switched" off. The advantages with a parallel implementation include (1) less disruption to the business, and (2) no loss of business if the new system suddenly fails.
