“My experience shows that proper testing and documentation is the first thing that management wants taken out of the story, often with the excuse "We can handle that in a later sprint." But since your life is a neverending series of sprints (note: that's actually an ultramarathon), and management gets to pick priorities, you may never return to the technical debt.”—klyrs, https://news.ycombinator.com/item?id=20017854#20021832
“I regularly ask ‘Why are we running a marathon in a thousand sprints?’.
Besides tech debt, a concern I have that I don't see brought up is burn out. With Scrum, every action you perform is micromanaged and with a push for ‘high velocity’. There is no proverbial breathing room in this where the pressure lets up. At least with waterfall (for how we did it before Scrum), the windows of high pressure times were shorter. During the beginning of our 6 month waterfall, in parallel to spec work we'd be taking care of tech debt or implementing our pet feature and it was a time of mental recovery.”—epage, https://news.ycombinator.com/item?id=20017854#20021832
