      Do you consider it waste to re-estimate a PBI when there is material new knowledge about that PBI that would materially affect the estimate for that PBI?

      Hi Greg,

      I think following George's and Avi's advice is probably the best way forward for you.

      I might just offer a brief word about Release Planning between the development team and the product owner. In general, the epics in the backlog should be roughly estimated in story points, days or weeks, whichever is most appropriate, and from that rough release dates are established. This can be done before the first sprint. Assuming these epics are estimated relative to each other, no re-estimation is needed; re-estimation is usually a form of waste.

      Take a look at Mike Cohn's book, 'Agile Estimating and Planning' and Roman Pichler's book, 'Agile Product Management with Scrum' for more information on release planning.

      Good luck,

      Bob Boyd
