System Architecture Virtual Integration: ROI on Early Discovery of Defects
November 2018 • Podcast
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.”

In this podcast, Peter Feiler discusses the economic effects of the System Architecture Virtual Integration approach on the development of software-reliant systems for aircraft compared to existing development paradigms. The analysis showed that the nominal cost reduction for a system that contains 27 MSLOC would be $2.391 billion (out of an estimated $9.176 billion), a 26.1 percent cost savings.
About the Speaker
For the last 32 years, Peter Feiler has been a member of the SEI, where his duties included five years of management. His interests include safety-critical embedded software systems, architecture languages, and software system assurance.
Feiler is the technical lead and author of the SAE AS-2C Architecture Analysis & Design Language (AADL) standard. This standard was originally published in November 2004 as SAE document AS5506. Version 2.2 of the standard was published in January 2017. Feiler also was the author of the Error Model Annex V2 Annex standard for AADL, published in 2015.
Before joining the SEI, Feiler conducted research and led a group in software technology at the Siemens Corporate Research and Technology Lab in Princeton, NJ. During that period, he was the system architect for the software development environment in large-scale product development.
Feiler received the Carnegie Science Award for Information Technology in 2009 for his work with AADL.
Feiler earned a PhD in computer science from Carnegie Mellon University and was appointed SEI fellow in August 2016.
