Answer to Question 1

A parallel implementation process launches the new system while the old one is still running. Employees either do their jobs twice, once on each system, or two separate teams handle the same processes, one team on each system. An advantage to this approach is that both systems are processing the same cases, so if the new one is operating properly, the output should be the same. However, parallel implementation is very expensive and thus is usually in place for only a short period. Also, if the old system is being retired because it bungled some processes, the comparisons might not be valid.

Answer to Question 2

D
