It allows to customize workflow by defining own rules of issues processing. It's possible:

• To change issue properties if some conditions are met;
• To create new issues programmatically if the conditions are met (for example you can create an issue in another project if the status of source issue is changed to specific value);
• To raise custom errors which will display to user, if he does something wrong;
• To do anything that conforms to your needs;
