AGILE SCRUM ESTIMATION TECHNIQUES
Over time, as team members encounter new user stories, they should develop an increasingly accurate sense of how they’re going to approach stories and how much effort each user story will take to complete. Once a team has been working together for a while, their ability to estimate new stories becomes much better. Teams with a history of past successes and failures can compare their velocity against point estimates that everyone can agree to, and as a result they can predict with reasonable accuracy how difficult it will be for them to complete a new story. But teams new to agile sometimes have difficulty figuring out how to estimate stories effectively. For some, the abstract and team-specific concept of points is difficult to grasp. For others, the soft relationship between point value and actual time spent working on a story can be distracting. Until a team has been working together for a while, attempts to generate accurate point estimates for new stories may feel awkw...
