We are using Jira for agile PM, but are having problems working with both story points and sub task hours estimation.
Articles like this and this just don't seem to help. The second article has a graphic image which doesn't seem to match the description, so we are quite stuck. I have read through this excellent description of why use both, and I am convinced.
We want to do story point tracking from a high level point of view or can run just with sub-tasks and track estimates of hours but not both at the same time.
-- Edit
The reason we think we need to do both types of estimation, is that the user stories we have cross over three skill groups of staff and have (e.g.) 8 story points. So in tasks estimated, could be 6 days SQL, 1 day .net, 1 day HTML, or it could be 1 days SQL, 5 days .net, 2 days HTML, but I won't know until I estimate tasks. So from a staff planning point of view I (as the scrum master) want to know that I have the right number of user stories / sub tasks / staff mix for the sprint. I cant do that unless I estimate sub tasks.
Or am I missing something?
