The rapid development face-off was a competition between rapid application development (RAD) teams from the leading consulting firms in the United States. The goal was to see which team could develop a specific system in the least amount of time. Most teams used a very short program design step and quickly began programming.
The Ernst & Young (E&Y) team members used a different approach. They spent much more time in the program design step to ensure that the system was well designed before they moved into programming. At first, the E&Y team fell behind while its competitors jumped ahead. But E&Y ended up winning because the team spent much less time programming by following its well-designed blueprint.

QUESTION:
What are several reasons why planning ahead may have helped E&Y win?
