Find out all assigne of a task

[Carlos Oliveira]

Folks,

I have a team and during all the execution of the task, I must report to the management, who were all the participants of the same.

Since we are in a systems manufacturing team, it is necessary to report who participated in what activity.

Can someone help me?

It's a bit late now, but you can install the JIRA Toolkit Plugin. It has a 'participants' field along with some others.

Hello Joe

We already have the kit installed, where there is the "Pie Chart", "Filter of two statistical dimensions", but I can not see in a single species of activity verified all participants (assigned) in the same way, for example:

All who have received in the field assigne their respective task, based on the history.

In other words, in task 1, we had: 1 QA, 1 BA, 1 Developer

The final need is to show how many tasks each person on the team participated in, based on the history, not the last user to put the status and assigne.

I am deepening the knowledge in the tool in this period, that is, everything is very new.

If there is a JQL to be applied to filter the story, let me know.

I guess if a user is assigned, but never comments or updates the issue they aren't tracked.

In this case the activity is assigned, and each passing phase changes the status to the next responder.
