Question

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.

Please Explain!!!

Explanation / Answer

Global cooling was a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere along with a posited commencement of glaciation. This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the scientific understanding of ice age cycles. In contrast to the global cooling conjecture, the current scientific opinion on climate change is that the Earth has not durably cooled, but undergone global warming throughout the twentieth century.
