Timer Expired and Tool Policy Example
The following example illustrates both the timer expired event and the timer tool
policies. This workflow is initiated when the system receives an order. Then, an account manager must access
the relevant ordering system, review the order details and either approve or reject
the order. If the order is not reviewed within a certain time threshold, then the
users within the Account Manager group are notified. The users are notified by e-mail
up to three times before the order is escalated and reassigned to a senior manager.
The remaining workflow
tasks are similar to those in Basic Approval Workflow.

The following table
lists the timer settings for the timer policy associated with the
main workflow. These settings trigger a transition to the Review Escalated
Order task after 10 minutes. Another policy is associated with this
task that stops the initial Review Order Task because the order has
been automatically reassigned.
