Tip:

In Web Client, the drop-down list at the top left allows you to select the way participants are grouped when displayed in this section. The options are Group by Role, Group by State or Group by None. The Group by None option lists all participants in the review in a single list which is sortable by clicking the headers for each column (name, role, state).

There are the following states of review participants:

Active: participant is going to do some action to move review process forward: creating comments, adding changes to the review materials, etc. For example, when reviewer creates a defect and sends review to rework, author is moved to Active state (because author needs to address the defect).
Waiting: participant is waiting for specific activities. For example, when the author sends review into Inspection, author’s state is changed to Waiting (because he/she is waiting for reviewers' feedback).
Sent to Rework: participant sent the review to the rework, while other participants still are in Active state (reviewing). When all reviewers move review to the rework, author is in Active state, and reviewers are in Waiting (for some action like ‘File activity occurs’).
Approved: participant accepted changes in the uploaded materials.
Approved by workflow: participants in completed review, that didn’t complete review explicitly (usually for observers, moderators).
Completed: state of authors after completing reviews.

Add or Remove Participants

Web Client

Unless the review is in the Planning stage, the Participants section will be in read-only mode. To add or remove participants or change their roles, click the Edit button. The Participants section will look like this:

To add yourself as a participant in the review, select a role in the Add Myself As area.

To add another user as a participant, select the desired role in the Role drop-down menu, then select one or more users in the Participants drop-down menu, and click Add. (The Participants drop-down menu displays only the first 1000 users.)

Tips:

To filter the user list, start typing the name of the desired user. The list will display only those users that contain all typed characters.

To select multiple users, just click each desired user in the Participants drop-down list.

To select a range of users, click on the first user, hold down the Shift key and then click the last user.

To select all users (respecting current filter, if any), click Select All button.

To clear previous selection, click Clear All button.

The Filter by drop-down is used to choose a group whose members are then listed in the Participants drop-down menu. If there are no groups associated with the review, the Filter by drop-down is not displayed. This field displays only the first 1000 groups and it excludes groups which have no members.

User/role combinations you have used recently will also appear under Recent Participants. This makes it easy and fast to select common combinations.

To change a participant's role, select a new role from the drop-down menu in the Role column.

To remove a participant, click the Remove from Review button.

Once you are finished editing the review, click Done Editing.
