As teams groom their backlogs and estimate upcoming work, it is often helpful to look back at already completed stories to find sizing estimate data points for comparison. For instance, if the team is sizing a new story and are wavering between say, a 5 and an 8 point estimate, it is much easier to make that decision by looking back at several stories they have done in the past that were sized as 5's and 8's. This allows them to triangulate their estimate among multiple data points, which should help the accuracy of the estimate. A "Story Estimation Net" component in VersionOne would be really handy for this purpose. I could see this being a button in Estimably called "compare to previous stories" that would bring up a list of closed stories with their sizes. I would want to see them grouped by size in a visual way such as:
1: Story x, story y, story z
2: Story a, story b, story c
3:...
5:...
8:...
etc.
Another way to implement this would be to make a stand alone button in the teamroom, or even a report that's easy to access.
