Upon receiving a request from the sales department for pricing on a specific line item taken from RFQs (Request for Quotation) received by sales, Jim Durr, a pricing specialist at Divine Products purchasing department, performs the following actions: [Note: In the following you can assume that the pricing specialist is using a computer-based application to keep track of the discounts and pricing being applied to the item being priced. This process focuses on pricing. Sales is considered external to this process.] Process Details First he determines if the customer is a high-volume customer by checking the customer database; if so, then a 10% preferred customer discount is applied (regardless of any further discounts the customer might be entitled to). Next, if the quantity of the order is over 100 units, an additional discount of 10% is applied, unless there is an applicable, current supplier discount thats greater than 10%. If the current supplier discount is greater than 10% then that discount is used instead of the quantity discount. If no quantity discount is applicable but a supplier discount is, then the supplier discount is taken, regardless of its percentage. After calculating the above discounts he (Jim) sends back his discount response to sales and waits for them to either confirm that the quoted price is acceptable (in which case the processing ends) or, if not, sales then requests a re-calculation based upon an equivalent item from another supplier. In the case where sales request a recalculation with a different supplier, Jim returns to the beginning of processing with this revised supplier information. If Jim doesnt hear back from sales within 24 hours, he assumes all is well, then closes out (ends) this specific pricing request transaction. To-do: 1. Develop a BPMN-compliant process diagram for the above scenario. Use two pools to indicate the interaction between sales and purchasing.
