Kudos to the original creator Dragan Stepanovic.
I came across this slideshare that explores the relationship between the size of pull requests and flow efficiency. As any analysis of this type, it can only be as good as the data that is used in it.
Notwithstanding the conclusions of the author, it is interesting to see flow efficiency measured at that level.
I figured I could share in here for those of you interested in this aspect that is so prominent in Tameflow.
