Jira is a little tricky when it comes to having multiple people assigned to a task. By default, a task can only be assigned to a single person – this is meant to avoid any accountability issues when it comes to who is meant to be working on a task. The assignee can change multiple times over a tasks life, or subtasks can be assigned to other people. However, sometimes it's just important to have multiple contributors on a single task. We got around the single assignee limitation by adding a ‘collaborator’ field, that multiple people can be added to.

To view all of the tasks you’re a collaborator on, there’s a few ways of doing it:

 There is already a filter configured for viewing all tasks you're a collaborator on:

1. Click the filters dropdown at the top of the screen, and select View all filters.
   
2. Click ‘Tasks Assigned to Me or Collaborating On” – This will show all the tasks where you’re marked as the assignee or as a collaborator
   
3. Or Click ‘Tasks I’m Collaborating On’ – this will show just the tasks where you’re marked as a collaborator.
   

If you think this is a view you’ll use a lot, you can star it so it sticks in your filters menu, or you can edit your default dashboard and add it in there.

Adding it to your dashboard:

1. Click the Dashboards dropdown and select View all dashboards
2. Click Default dashboard
   
3. Click Edit in the top right corner
   

You can do all kinds of neat things with the dashboard layout, but to add the filters mentioned above:

1. Click Add gadget in the top right corner
2. Find Filter Results and click Add
3. In the new Filter Results widget, for Saved Filter, select the Collaborator filter you wish to use (ie. with or without assigned tasks)
   
4. Choose your other options. What I did was the following:
   
1. Number of results: 1
   
2. Columns:
   
1. Issue Type
   
2. Key
   
3. Summary
   
4. Priority
   
5. Reporter
   
6. Assignee
   
7. Collaborators
   
5. Click Save

I then removed the default ‘Assigned to Me’ filter from the dashboard, and set the layout to a single column by choosing ‘Change layout’ in the top right corner. I then use the dashboard to view all the tasks that are assigned to me, or I’m a collaborator on regardless of what project board it’s on.
