“Project Scope” users can choose a single project, multiple projects, or global(global means ALL projects) for the rule that the user wants to implement it.
“Assignment Strategy” users can make a selection between Round Robin or Random. Let’s assume that we defined more than one assignee, round robin represents that, while implementing the rule assignees will be selected respectively instead of the absent user and random represents that, the user will be selected randomly between the assignees.
“No Assignment Scenario” consists of Alternate Assignee, Unassign and Do Not Reassign. Let’s assume there are two users(User A, User B) which who are considered as assignee assignees in the Add Assignment Rule screen and a random issue is assigned to User A. However User A is absent. On the other hand, User A had defined a rule for himself before from the admin section configuration page which is(If User A is absent, an alternate user will be User B). Then, that predefined rule will be working instead of this rule. Unassign means if the selected assignee is absent then the issues that are assigned to that user will be automatically set as unassignunassigned. Do Not Reassign means, nothing will change if the selected user is absent. The issues that are assigned to the absent user users will remain the same and the assignee will still be the same user.

There are two post functions that users can add to any transition as seen in the figure. First The first post function (Assign By Rule) does that, assign assigning users according to assignment rules (Global Rules and Project Rules) which matches with the appropriate issue that is defined before. Second The second post function (Assign To Alternate User) does that, assign assigning to an alternate user when a user is currently unavailable.
