LeanDog Blog How to Estimate Agile Stories: Introducing Relative Sizing

The truth is, without a good system, most of us are bad at estimating. We often overrate how much we can get done. For traditional companies that spend weeks or months making lengthy plans, disruptions are bound to derail the best estimates. As an agile team, you want to avoid long, unpredictable planning cycles. You instead work in precise sprints or show work in progress on a Kanban board.  Though agile iterations are shorter and more adaptable, estimation is still the only way you can communicate to leadership when work will be delivered.  Over time, estimating enables us to know our team’s velocity so that we can accurately forecast work.  Estimate better, and faster, with relative sizing.
