I'm interested in what others are doing to reflect future PI plans and roadmapping at the feature and story level. Are you using the 'release' & 'iteration' designations for future PIs to depict a roadmap plan? If so, do you find that behavior skews your scope metrics with changes as you get closer to beginning that work? I've looked at those two particular fields as actual scope committments based on what happens at PIP and during iteration planning sessions. For features there are 'planned start/end date' fields available for planning purposes but those fields are not available at the story level. How are others leveraging these fields?
