Average Age Chart gadget from Dashboards - How to interpret a drop?

[lorenzo_betto]

Hi! I'm looking at the Average Age Chart from my team (it's split into weeks) and in the last week it shows a nice drop in age. 


How should I interpret it? Does it mean that in that week we closed tickets that were rather old and therefore the age dropped? That would be my explanation, but I don't see very old tickets in the list of recently closed tickets.

Hi @lorenzo_betto,

Have a look over this article; it explains how this gadget works: 

How is the Jira average age report calculated? 

Hope this helps.

Danut.

Hi Danut, I read the article already but I still can't explain why the drop happened. I would imagine a drop when I close very old tickets, which means that the average age goes down. But we didn't close any old ticket during that period. Just a bunch of mostly recently created tickets.

Hi @lorenzo_betto 

This chart is to show issues on a daily basis that are not resolved for a certain number of days.

What is the origin of the chart, is this a filter or simply a project?

If this is simply a project, the number per day looks at any unresolved issue, including even todays created issues.

"No matter what base query you are using for the Average Age Chart gadget, it always calculates age based on the duration for which an issue is NOT resolved or closed.

To overcome this, you need to resolve issues, wherever applicable, before you try to analyse the gadget.

As you may be aware if an issue is updated, it's an issue in progress for Jira."

I'm using a filter to show all tickets except Epics and Sub-tasks from one of my projects. So I am including closed/resolved tickets too. But I think those should be included, shouldn't they?

Minor correction: my chart is showing weekly data, not daily.

And I'm still confused, how do you interpret the drop in average age from the last week in the graph?

Hi @lorenzo_betto 

More issue have been set with a Resolution.

Issues which have not set a resolution show in this dashboard gadget graph.

Sorry I don't understand. Could you rephrase it please?

Hi @lorenzo_betto 

If you set an issue to a "Done" state (green), by default you need to set a Resolution, like:

• Done
• Won't Do
• etc...

If this is set the issue will not be involved in the chart, if this is not set the issue is still considered unresolved.

[lorenzo_betto]

The issues are indeed set as Resolved when I move them to a green status category. But from what I understand from this page https://confluence.atlassian.com/jirakb/how-is-the-jira-average-age-report-calculated-967898701.html they will be included anyways! It says:

• We only care about the issues that are either still open, or whose resolution date is in the date range displayed by the chart.
