Roles as per workflow

[Seema]

1. I want to set a workflow, where I can assign users as per the workflow

2. If I create a new story , I want different resources to work on workflow for that story only

How to implement this in JIRA

Hi Seema - Welcome to the Community!

1. In the workflow, select the transition for when you want to set the assignee. It can be the create transition.  :-)

Then add a post function to that transition to Update issue field. 

Then select Assignee and add your value.

2. Take a look at this link and see if it helps.
