Surprised by the downvotes. I'm just sharing what I've learned the hard way over the last 6 years.
We can easily tell that the sprints where we managed to break something down further, has been better estimated and more productive.
Call it micromanagement if you'd like. What is working for one team might not work for another.
That’s a great point which I will take with me. Might be somewhat biased since we only done greenfield.
