Boeing also cut corners on quality, hence the issues with the 737 MAX. It's obviously not a direct comparison, but skimping on certain things to get something to market faster is not a uniquely SaaS technique.
Although it could have quality problems; stories of 787 quality problems are concerning. But quality skimping was not the cause of the 2 fatal crashes
When it was time to fly there were slight differences and this caused the pilots to react in the wrong way for the new model's behaviour.
While I understand the reasons you mention, I do not clearly follow the distinction between cutting on costs and cutting on quality. It seems like two sides of the same coin.
[1]: There is very low heat cap on middle tank to catch fire inside and be exploded and then there is an air compressor right below it. The security practice is to fill it with nitrogen if it's empty.
Have those two teams work together.
Also, foster a culture of continuous self-improvement. I’ve now seen a bunch of “it’s good enough to ship, go for it” and now whatever work arounds and bandaids are permanent. Don’t be so fast, don’t try to iterate so quickly, and focus on quality over quick ROI.
Imagine if Boeing behaved like a SaaS operator. The first version of 737 would be glued together, and in turbulence the wings would snap off “oh, I guess we should use more glue in the next version - alright guys, iterate!”
Slow down, do a good job, and the product will come.
