-Many people worry that Story Points do not help us estimate effort. They are after "​estimates"​ - how does that workThe reality is that point based estimates provide a more realistic view than time tracking systems.+Many people worry that Story Points do not help us estimate effort.

-It turns out that "estimated effort" ​is highly correlated with actual work time. Agile practices help teams drive toward high correlation between ​estimation ​points and actual time. One goal of agile is to improve overall forecasting starting with the commitment made during sprint planning. Teams that embrace agile estimating principles examine their estimation points and outcomes, trying to ensure that their sprint forecasts are roughly met by the sprint result. If there is wide variation, teams would discuss improvements at a retrospective (see [[what_can_we_do_to_improve_our_point_based_estimates|What Can We Do To Improve Our Point Based Estimates?​]] for specific ideas on this).+It turns out that a story point view of estimated effort is highly correlated with actual work time.

 In many ways the approach leads to better tracking of effort. When we track stories, estimation points and completion dates (sprint end dates), we know exactly which team did the work, we usually have a day-by-day task burndown and we have a proportional allocation (see [[how_do_i_convert_points_and_velocity_to_dollars|How Do I Convert Points and Velocity to Dollars?]] for more information). The stories are well documented and understandable (thanks to the user voice form). Team members say the same thing executives say when asked about work as there is a common language and understanding. This means when someone sees something a report and want to ask more detailed questions, no matter where that query leads, there will be a common understanding. In many ways the approach leads to better tracking of effort.
