For his part, UPS's Hilbush says that "a key lesson learned is that you need to do the iRise simulation as early in the development cycle as possible and you need to include both business users and developers; it is the business analyst who typically does the iRise simulation." Because the business analyst is part of the development team at UPS, the developers are typically involved, hence they don't give up a great deal of their creativity. "If done well, the process is very open and collaborative," Hilbush says.
MD Andersen has cut about 25 per cent off of its overall development time by using simulation, says Dr. Lynn Vogel, vice president and CIO, adding, "Our dream would be if simulation would generate all the code. But that's a very difficult process. Coding is as much an art as a science."
