Coming from my last post How abstract really are story points? I had the idea to share with you some websites where, completly free of charges, you can start your Agile Scrum estimation meetings.
I already did many Refinement meetings (or grooming meetings, as you prefere it). I think those are my favorite AGILE ceremonies, that moment where after a delicious, creative and smart discussion everybody selects THE CARD!!! There you observe so many things: who leads, who knows, who loves risk, who is more cautious, who influences, who will implement it 🙂
