Definition
Relative estimation is one of the various types of estimation methods that are used in Agile Teams. It comprises of the process of estimating tasks and user stories, but not in absolute units of time.
Relative Estimation avoids some of the drawbacks of estimating in general, like seeking unwanted precision, and confusion of estimates with commitments. This is due to it being synchronous with units other than time in estimation.
