Admittedly, not a question unique to GreenHopper/JIRA, but does anyone have any insight into an appropriate unit and scale for assigning "Business Value" to stories and epics?
I have seen references online to Business Value = 100? Seems rather arbitrary to me, so interested to get some lessons learn't from people who have used this measure for planning purposes before.
At the moment I am considering the range [1 .. 10].
For story points we use a Fibonacci-esque sequence [1,2,3,5,8,13,20,100] as a measure of relative costs in terms of implementation effort/time required.
