Often, you will have transitions that need to be made available from several different statuses in a workflow, such as the Resolve and Close transitions. In other words, these are transitions that have a common destination status but many different originating statuses.

To help you simplify the process of creating these transitions, JIRA lets you reuse an existing transition as a common transition if it has the same destination status.

A common transition has an additional advantage of ensuring that transition screens and other relevant configurations, such as validators, will stay consistent. Otherwise, you will have to constantly check the various transitions every time you make a change to one of them.
