I bet, by now you know enough about the recent scum guide revision. It has taken us years to adopt to Scrum and some of us are still understanding the adoption process. The new scrum guide is more powerful and provides you more opportunity to derive value from it. Like SAFe, Scrum guide is relatively less perspective and focus is on whole team accountability.
The purpose of this article to highlight the changes on the scrum guide section by section, I'll leave with the readers to articulate the changes. I've attempted to make a section by section comparison on a high level. Please post a feed-back or highlight any changes which needs to be captured here.
