Similar problems still exist, turns out software is hard: https://medium.com/backchannel/how-technology-led-a-hospital...

Nice article, thanks for posting it.

It's ironic that this article mentions the Toyota Production System as an example of a safe and defect-free system. Another article about Toyota was posted on HN today:

«Toyotas Unintended Acceleration and the Big Bowl of "Spaghetti" Code (2013)»

http://www.safetyresearch.net/blog/articles/toyota-unintende...

Apparently Toyota's software development doesn't follow the Toyota Production System.

OK, that was a flip comment; it's pretty clear that TPS isn't suited to software development. However, it does seem clear that Toyota's software development practices are deficient.

More a case that UI is hard - and too easily neglected by our current approaches to safety-critical software.
