Venkatesh Krishnamurthy writes The 4 Ingredients of Building Hyper-Productive Teams. What he means are agile teams, quoting Jeff Sutherland:
We define Hyper-Productivity here at 400% higher velocity than average waterfall team velocity with correspondingly higher quality. The best Scrum teams in the world average 75% gains over the velocity of waterfall teams with much higher quality, customer satisfaction, and developer experience.
Agile for me, though worded awkwardly: how do the best scrum teams compare to the best waterfall teams?
