I have bad news for you about health care professionals.
Health care professionals is a weird one, because while long shifts are dangerous, patient handover is also dangerous and there may be an argument that longer shifts means fewer handovers which could result in better patient outcomes.

#82Reminds me of a quote attributed to Thomas J Watson: Recently, I was asked if I was going to fire an employee who made a mistake that cost the company $600,000. No, I replied, I just spent $600,000 training him. Why would I want somebody to hire his experience?
Well be prepared to spend $600k more next month for the next “training” session.
Re: My $500M Mars rover mistake
#83Really well written story. As a software engineer, I have a couple stories like this from earlier in my career that still haunt me to this very day. Here’s a short version of one of them: Like 10 years ago, I was doing consulting work for a client. We worked together for months to build a new version of their web service. On launch day, I was asked to do the deployment. The development and deployment process they had…
Great story, thanks for sharing.

You can't apply process thinking here, where the scenario is custom testing a unique probe, and you don't know what other constraints are in play (for example, the reason for the plug design). If NASA were sending these things to Mars by the dozen, then you can start to formalize things like test procedures and look for places mistakes can happen. But in this scenario, you're just disempowering your staff by not lett…
Aerospace-grade connectors are specifically designed to support multiple keyings that prevent this kind of thing. It's definitely a problem preventable by careful design if the interface supports making this kind of mistake.

That just means that doctors need to handle fewer patients.

#87One thing about long aerospace missions like this with huge lead times that always gets me - you can spend years of your life working on a mission, only for it all to fail with potentially years until you can try again. This is a refreshingly humanizing article, but is also one written from the perspective of a survivor. Imagine if the rover were actually lost. I asked the question "what would you do if the mission f…
Incidentally, this happened to Lewicki a few years later when Planetary Resources' first satellite blew up on an Antares rocket: https://www.geekwire.com/2014/rocket-carrying-planetary-reso...

The point is that they won't make the same mistake again
Re: My $500M Mars rover mistake
#89I'm reminded of the phrase - if your intern deleted the production database you don't have a bad intern; you have a bad process. Whether this was a process problem or a human one we don't really get to judge since we do expect more from a FTE. I'll just say putting myself into his shoes made me tear up as I read the dread and pangs of pain upon realizing what happened - then to have life again after the failure of th…
The first thing mentioned in the post mortem call was “No one is going to blame the guy who did those trades. It was an honest mistake. What we are going by to do is discuss why a developer can hit the production trading API without any authentication at all”.

Would we accept this if they were dealing with nukes, rather than people? Yeah we let people who haven't had sleep in 36 hours handle the nukes because having the people involved talk to each other between shifts is hard.
