information radiator.  Stories and tasks on the information radiator should make visible the order in which they are being worked, as well as serve as the center of focus during the daily Scrum. Team members should be encouraged to physically touch the stories and tasks on which they are working, and be restrained from moving to new stories until a reasonable chunk are completed.
Finally, in the spirit of keeping Agile light, adding burn-up to the burn-down to form the Agile-V Scorecard is suggested, not required. A well-established Agile team that understands the importance of delivering value with each sprint will naturally focus on priorities. For organizations new to Agile, the Agile-V provides a daily measure of the team's focus on delivering prioritized business value. This daily feedback helps establish the proper rhythm and pace that are intangible signs of a mature Agile team.
The Agile-V Scorecard provides a clear snapshot of effort remaining (burn-down) and business value completed (burn-up). By itself, the burn-down chart provides a clear view of effort remaining, but it can potentially hide how well the team is focusing on incremental completion of business value. Pairing the two charts provides apowerful driver-output pair. Since the burn-down is a direct measure of work driving the current sprint, and the burn-up is a direct measure of business goals, the Agile-V scorecard provides a tightly linked, tightly controlled, direct line-of-site to business value. Using the Agile-V Scorecard ensures that most important work is focused on and completed as soon as possible. This will naturally result in the implementation of a fundamentalprinciple of Agile -- don't build what you don't need.
