I'm a Scrum Master leading a software and infrastructure team to completion for a data, web service and UI project. We are about half way through the project. Currently the project is lacking enough backlog stories to accurately predict what the team is able to deliver in 6 months or even 3 months. I set up Jira with three new version names but our release to production is realistically at least 6 months away.
Our stakeholders would like to get a reasonable forecast based on their original scope document which we are working from to create more user stories. Besides the obvious of creating a ton of more user stories...
My question is what else can I do in Jira to reflect the current situation as well as best guess forecast?
