I'm trying to figure out how JIRA can help track an Agile Scrum project we are running, in particular I want to be able to create burn down charts.
I created a few stories and tasks, and noticed that I can only enter in story points for epics and stories, though it seems like this may be configurable. Specifically, the documentation says this:
Many Scrum teams separate estimation (which is used for measuring the size of a backlog and calculating velocity) from tracking (which is often the burndown of hours used during the Sprint to be sure we're not way off the pace necessary to complete the stories in the Sprint timebox), and use different units for each.
(info) Note that, by default, the Story Points field is only available to issues of type 'Story' or 'Epic' — you can change this as described in JIRA Agile - JIRA Configuration.)
I've went through some basic Agile training and I haven't come across this concept yet where the tracking and estimation is different, though I am sure some people do it that way.
I considered trying to configure JIRA to use Story point estimations for tasks and sub-tasks, but before I try that I want to understand what the flow used by "many scrum teams" in JIRA.
Furthermore, it seems that the "log work" option once a sprint has begun doesn't effect the story points estimation at all. With the current flow, it seems like I would have to enter in the estimation in story points for epics and stories, and then re-enter in something similar for the time estimations for every item.
If someone can help me with a recommended workflow where I don't have to enter in everything twice, and I can do a day-to-day tracking of how much each story/task/sub-task is completed (with burndown chart), I'd appreciate it.
UPDATE: I tried showing a burndown chart and I see it only shows story points, which I guess is as expected. My problem is that this means none of the tasks or sub-task completion will reflect on the burndown chart, which seems strange.
UPDATE 2: By changing the board time estimation mode to "Remaining Estimate and Time Spent" I was able to select "Remaining time". However, when I close sub-tasks, for some reason that chart doesn't adjust. It seems that I have to manually update the "remaining time" to "0" which is a pretty awkward interface (why doesn't it do this automatically?). Furthermore, my fundamental problem of needing to manage estimates and tracking in different places is not solved.
