Embedded System Software Quality: Why is it so often terrible? What can we do about it?

I had a great time meeting old friends and new folks at ISSRE 2016.

Here are slides from my keynote address:

Embedded System Software Quality:
Why is it so often terrible? What can we do about it?

Failures of embedded system software increasingly make the news. Everyday products we rely upon are suffering from safety issues, security issues, and just plain bugs. While perfection is unrealistic, surely we can improve this situation.  Two key ideas apply: (1) embedded products often aren’t created by computer specialists, and (2) teaching application domain specialists just how to code is more of a problem than a solution.
