Our project manager at Karos Health shared a link with us the other day about Swarming.
This is the first time I've heard of this technique and it sounds quite interesting. The idea is that you get all the developers to work (swarm) on a single story, instead of having each developer working on a separate story. The goal is to get more stories fully completed. It's better to have 80% of the features 100% done, instead of having 100% of the features 80% done.
I also think having many developers focused on a single story encourages collaboration and teamwork. It forces everyone to work together very closely, and this probably leads to getting the story done faster.
Of course, the story in question needs to be big enough to allow multiple developers to work on it together without stepping on each other's toes. If our J3WAO stories weren't so small, I think it would be interesting to try it there.
