Is Scrum supposed to increase velocity? I always view these processes as a consistency enhancer. "What can we accurately promise 6 months out" vs. "how can we get the most done possible?" This is important because the big risk is that you do 80% of 10 projects, rather than 100% of 1 project, especially if you have a team and not just a couple of individuals.

Lots of stuff pushes organizations in the direction of doing 80% of 10 separate projects, and it's a killer. This is good reading in this domain: https://apenwarr.ca/log/20171213
