Is it possible "assigned task can only be changed by the assignee"

Batuhan Akpunar

I want that "only assigned" user allowed to change status of an issue.

Let me explain my problem with an example.

There are 3 users in my workflow. One supervisor, one analyst and one developer.

If analyst assignee an issue to developer (Open --> In Progress) , I want that supervisor has no permission to change the status.

Is it possible and how?

Thanks (sorry for poor english)

Yes. 

You need to edit your workflow.  Look at the transitions (the arrows in the diagram), as these are the things that people click on to make the status change from one to another.

Transitions have a set of things that control what they do and who can use them.  Look at the "Conditions" for the transtions you want to protect.  Conditions are there to say "stop this transition being available if <something>".  So, you can add a condition that says "Only the assignee can use this transition".  And you can build more complex cases such as "only assignee or reporter or admin can transition, and the user has to be in the developer role"

p.s. Your English is good.
