This timebox (Timebox 01) runs for about 3 weeks and the scope of work targeted is forecast to complete right at the end of the timebox -- indeed a couple of the tasks are alread critical. (This diagram is looking forward, predicting when tasks will close, and thus when the work in each task will burn down). Look at the same time box a couple of days later.
When we visit the team half way through the timebox we can see from the burn down chart that they are still very much on track and confidence will be high that this team will deliver on its promises.
