I forced every engineer to take sales calls and they rewrote our platform

The root cause I think is that nobody really cares. They're not paid extra to care, either. The PMs are putting checkboxes together and writing reports for their managers without really asking how what they are designing is going to actually be used, the engineers are turning each checkbox into code without wondering if what they are doing makes sense, and the project managers are making sure the train is running on time without regard for where the train is actually going. At the end of the day, the company's stonk goes up, everyone gets paid, and goes home to the family they care about and to do hobbies they actually care about. If any of these characters in the play goes above and beyond to do something wonderful, they aren't getting paid more, the stonks aren't going up higher, and the effort is usually just wasted. I'm not saying this is bad, either, it's just part of why products are so bad.
