Is it possible to restrict workflows by person?

[Justin Corcoran]

In a workflow for a particular item type, there are steps that only certain people should be able to have control of. As an example, only QA should be able to mark an issue as "QA In Progress" or "Failed QA". Is this possible?

Yes, you can use Condition to limit who can see a transition. Go to your workflow step, select the transition, and then click Add on the Condition tab. There are several conditions to choose from. It sounds like you may want "Users in Group" condition which allows only users in a given group to execute the selected transition.

Even better than "User Is In Group" is to use "User Is In Project Role, because then you only need a project admin to manage roles, as opposed to a system admin to create and manage groups.
