Case: You are a systems analyst at Global Cooling, a leading manufacturer of air conditioning units. You are leading a team that is developing a new production scheduling system. The project is now in the application development stage. Unit testing has been completed, and you are in the final stages of integration testing. Your supervisor, Ella Pham, is eager to implement the new application ahead of schedule and asked if you could trim system testing from two weeks to three days, and use a direct cutover method instead of the parallel changeover method that originally was planned. Write a brief memo expressing your views.

Question: What type of implementation such company should pursue? Direct or parallel? With parallel operation more labor costs should be involved and it may be OK for a big company but how does the small business owner absorb these costs? What if there just isn't personnel available to do this extra work?
