For some projects, testing with simulated data or live data is just a matter of changing data set files and setting up some new systems configurations. However, for some other projects, selecting either simulated data or live data for testing is a big concern for systems analysts because their decisions would affect other groups. If you are preparing a detailed test plan as a systems analyst, please explain your proposed testing strategies plan regarding the use of either simulated data or live data. Will you use simulated data or live data? Why?
