Ken Schwaber and I had a spirited discussion answering questions from the audience at the Agile Boston conference on 25 November.
I started off the day with "Practical Roadmap to Great Scrum: Systematically Achieving Hyperproductivity." Several people have asked for data on story process efficiency which typically is about 20%, i.e. if a story takes one ideal day to implement it takes five calendar days to deliver on average. When you raise your story process efficiency to over 50% you will double your velocity. Systematic Software Engineering in Denmark, a CMMI Maturity Level 5 company, has provided extensive data in this presentation which will be useful to anyone interested in high performing Scrum teams.
