Big Bang
Once the management has decided to use the big bang method and supports the changes which are needed for this, the real changing process can start. This process exists of several steps: converting the system, releasing parts of the system and training the future users (Eason, 1988).
The activities in the process are explained in the table below, to state them clear. The concepts that are used to execute the activities are in capitals.

Famous quotes containing the words big and/or bang:
“Whenever there’s a big war coming on, you should rope off a big field. And on the big day, you should take all the kings and their cabinets and their generals, put ‘em in the center dressed in their underpants and let them fight it out with clubs. The best country wins.”
—Maxwell Anderson (1888–1959)
“This is the way the world ends
This is the way the world ends
This is the way the world ends
Not with a bang but a whimper.”
