Defects is probably the number 1 waste in software development. This is not a new thing, it has been a major problem ever since the software crisis was coined four decades ago. Creating software that works is hard. Creating software that works and does what the customer wants it to do is even harder. And with team members fighting as best as they can to meet a tight deadline, things get really difficult. I believe Kanban, combined with XP practices can help teams deliver high quality software at a reliable and sustainable pace.
