First, I appreciate this story, but it seems the author compares the build process of software to the production process of the car line.<p>It&#x27;s comparing the build stage vs the literal produce-the-thing stage.<p>I also think the stoppage of the production line happens in software.<p>If my code breaks while in production, I grab as many log files and stats as I can, roll back the code, deploy, and then study exactly why everything failed, and if we recovered post rollback.<p>That seems like the similar case on the car production line - haul the faulty model aside (get the logs&#x2F;metrics), figure out exactly what happened, fix it.<p>Who knows how the actual assembly line was put together. Maybe they iterated hundreds of times.<p>I don&#x27;t expect my code to fail in production, otherwise I wouldn&#x27;t have put it in production, but I understand it _may_ fail. That&#x27;s why I put in logging and metrics collection, the same way those engineers hauled aside the car.
