Peter Feiler discusses the cost savings (26.1 percent) realized when using the System Architecture Virtual Integration approach on the development of software-reliant systems for aircraft.

"If you discover [software defects] at system integration test, the cost of fixing a problem is 300 to 1,000 times higher than doing it upfront. So if upfront, you spent $10,000 fixing it, it's between $3 and $10 million on the backend that you are saving by the way."
