We're agile, so we don't have to estimate and have no deadlines, right? Wrong! This session consists of a review of the problem with estimation in projects today and then an overview of the concept of agile estimation and the notion of re-estimation. We learn about user stories, story points, team velocity, how to apply them all to estimation and iterative re-estimation. We take a look at the cone of uncertainty and how to use it to your advantage. We then take a look at the tools we will use for Agile Estimation, including planning poker, Microsoft Visual Studio Team System, and much more.
