I'm doing a neat hands-on activity at Agile 2011 called "Slackers and Debtors: Meet Commitments, Reduce Debt, and Improve Performance." It's a fun activity that illustrates how iteration velocity, technical debt, and iteration slack interact. Diana Larsen and I have used it in our Art of Agile Planning course for quite a while and it's always a hit.
The Agile 2011 schedule entry is here. I'll be in the Imperial Ballroom A from 3:30 to 5:00 on Thursday. Here's the blurb:
Does your team have trouble finishing its stories every iteration? Is your "done done" actually a "maybe maybe?" Are you constantly removing stories from your plan? If so, this session will help. We take a close look at the relationship between technical debt, velocity, and iteration slack. We teach you how to use slack to achieve a stable iteration velocity, increase team performance, and get your stories "done done" every time.
