Slide 11
Slide notes: The natural sequence is that a
User enters a Purchase Request. If the value is outside the User's
privilege level, it will pass to an Authorizer first. When a Request is
authorized either by the User or the Authorizer, it moves to the Purchasing
Manager, who assigns Purchase Requests to Buyers. A Buyer obtains source
and price, but needs final authorization before ordering the item. Final
authorization may be available from the initial authorization, especially
if the price is within the expected limit, else the Buyer will request
final authorization from the person
who initially authorized the Request, and then proceeds to order the Item.
