Who has ditched story points for probabilistic forecasting based on data?

[Carolyn McNicoll]

Story points had a time and a place.  But now we have methods (and Jira plug-ins) to forecast when work can be done, and a way of measuring a teams flow metrics so they can set a service level expectation they are able to meet.  It's based on data from their own work, rather than a gut feeling at a point in time.  

Have you tried Flow Metrics?  What do you love most about the transition away from story points?  

I love being able to answer the question "when will it be done", with a probability factor, rather than a hard date.  The forecast adjusts as factors change and you're able to keep your stakeholders informed.
