I don't really get this TBH.
Shipping speed never/is was the issue. Most companies are terrible at figuring out what exactly they should be allocating resources behind.
Speeding up does not solve the problem that most humans who are at the top of the hierarchy are poor thinkers. In fact it compounds it. More noise, nice.
Yep requirement gathering takes forever Then validation takes forever
Writing code is lesser problem than figuring out what we want when we want, and to get stakeholders at one place.
