Click the Rule tab.
Click Cascading in the Rule list.
When creating a Cascading rule, you must provide the following information:
Type the cycle limit in the Cycle Limit box. This is the number of times the work item will be cycled through the list of members before it is expired.
Type the timeout interval in the Day(s), Hour(s), and Minute(s) boxes, or enter the interval using the up and down arrow buttons. The timeout interval is the time that will elapse before the work item is forwarded to the next member.
Select the Enabled check box for each member who you want to include in the role.
Set the member sequence for receiving escalated work items. Right-click in the rule table, and click Order Members... in the shortcut menu. You can rearrange the sequence of members by clicking a member name, and then clicking Up or Down to move the member in the list. The order in which you arrange the members is the order in which they will receive the escalated work item, at the specified timeout interval.
