At the AgileEE 2011 Conference in Kiev I had the pleasure to host a workshop about estimation methods. The participants were quite excited, because the better part of them just knew Planning Poker and used it with and despite all of its limitations. We compared Planning Poker with the Team Estimation Game, which I discussed here on the blog some time ago (further links see below) and with Magic Estimation. While the Team Estimation Game has become more and more common over time and variations like Silent Grouping have evolved, Magic Estimation is not that common yet.
Let me explain Magic Estimation so you have another means for estimation in your portfolio.
