Burn Up Chart, that wasn't in the brochure!

Well we're doing the burn down chart. What a great visual tool. Right away I realized we're continually underestimating the work load, thusly producing a nice chart that burns completely bass ackwards. “Burn up” charts anyone? We kid about it, but it can be a serious issue. In our case we're fortunate that we're new to tracking our time in actual hours. I’m hoping to see our next sprint’s chart go in the correct direction. We have a great team so I am confident that it will with some discipline.
