The Scenario:

You are designing a workflow process to handle a purchase requisition for your organisation. When an employee creates a purchase requisition, his/her supervisor must approve it. When an approved purchase requisition reaches the purchasing department, a purchasing agent evaluates the record, and then performs one of the following steps:

• Rejects the requisition
• Creates a request for quotation to receive bids for the purchase
• Creates a purchase order from the requisition

The purchase requisition contains name, total price, quantity, and purpose (assume that the requisition is for one type of items). Depending on the price, additional approval may be need as described below.

Type C purchase requisition:

If the total price exceeds $1,000 but is less than $5,000, the requisition then requires the approval of a vice president (after the approval of the department manager) before it can be routed to the purchasing department.
