We are implementing Agile-Fall in my organization. 2 weeks sprints as we progress towards a defined Project End Date. In excel, we took the user stories and divided them evenly throughout a series of date bound, two week sprints, until we reached the Project End Date. Of course, this did not account for the size and complexity of the stories and led to a lot of scheduling.
In JIRA, we seek to do the same sort of Project Planning - plan out the entire projects in sprints but, I am looking for a way to do either What-IF analysis or an easy way to reschedule stories to determine Project End dates.
We are currently using the Version Report to determine potential Project Completion dates due to velocity but that is based on at least 10% of done tasks but, are there any other thoughts on how to provide this type of visibility.
I am sure there are questions but any help will be appreciated.
