This is the best description of Scrum (the software development methodology) I have read so far. It’s just long enough to have details and just short enough to be able to read it all without going over your TL;DR threshold.
This is pretty similar to what we do at work so I can associate with the whole post. I do have a few problems with scrum however. But I am very glad to read the description about how story points are designed to solve the problem between the need for estimates and the difficulty of giving accurate estimates.
