This short video explains how to estimates items in a product backlog and how it differs from task estimation. It introduces the notion of story points.

We are agile, so we don’t have to estimate and have no deadlines, right? Wrong! This session will consist of an overview of the concept of agile estimation and the notion of re-estimation. We’ll learn about user stories, story points, team velocity, how to apply them all to estimation and iterative re-estimation. The lab will consist of an estimation project and doing a round or two of “planning poker”.
