<h1>Order Management</h1>
Pending orders are shown here on the order management
screen for the store manager to process. Rather than
being data-driven, order management is process-driven.
A JBoss jBPM process assigns fulfillment tasks to the
manager based on the version of the process loaded.
The manager can change the version of the process at
any time using the admin options box to the right.

href="img/ordermanagement1.html">Order process 1
sends orders immediately to shipping, where the manager should ship
the order and record the tracking number for the user to see.

adds an approval step where the manager is first given the chance to
approve the order before sending it to shipping. In each case, the
status of the order is shown in the customer's order list.
