Summary: Jira needs real burn down charts. The current created vs resolved chart gives an idea of activity over a period, but no notion of the rate at which a project is approaching zero tickets.
Details: I use the created vs resolved chart, but it can be misleading. The actual counts and distances between the series are not very meaningful since the series always starts at zero at the beginning of the chart period.
The chart would be much more useful to me if there was an option to have the initial values of each series start with the total number of created and resolved on the date the chart begins. The logic would go something like this:
- Run the query to find all issue matching the filter
- Sum the number of issued that were opened before the start date of the chart
- Sum the number of issues that were resolved before the start date of the chart
- Use those two value as the starting points for the create and resolved series
Doing this should cause the colored gap between the two series to represent the actual number of non-resolved bugs no matter how may days the chart was currently showing (and of course the gap would never become green). I understand that this is a different use of the chart and should be an option (or maybe a new chart).
Here is an example that causes the current chart to look all "green" and not provide much value:
- 100 tickets are created 6 months ago and assigned as tasks to some release (call it v1)
- 6 months ago, those features are differed and moved into a future release (call it v2)
- As of today, v2 work has been going on for 30 days, and I am looking at the created vs resolved chart for v2 for the last 30 days. Over the past 30 days, 90 of those 100 tickets entered 6 months ago were resolved.
- Because I am looking at just the last 30 days, the chart looks all green and I appear to have negative numbers. The only thing the graph tells me is the resolve rate over those days. It tells me nothing about outstanding work, (and I see no other graph type that could show that graphically).
- But if each series started with the totals up to that point, then I would see a more traditional "burn down" chart that gives me an indication of how much work is actually outstanding.
