> The Max 8 is outfitted with bigger, more fuel-efficient engines than earlier 737s, and the weight and positioning of those engines shifted the plane's center of gravity forward, increased the potential for the nose to pitch up after take-off. To counteract this risk, Boeing developed software known as the Maneuvering Characteristics Augmentation System, or MCAS.

reminds a typical enterprise software project - deep serious issues stemming from screwed up basic architecture are hastily patched up by software patches. Sounds like it was a money saving architectural decision as development of more deep modifications to the airframe to allow for those engines to be positioned safely would definitely cost more than a software patch. And after the Lion crash the Boeing is doing patches for the patch ...
