Cuyamaca College ?creating a DFD’s and BPD With Visio Diagramming Tool Complete this assignment using Visio or another diagramming tool. Use good flowcharting practices to create your DFD’s and BPD. You will have three diagrams for this assignment. Submit your diagrams (in one submission) as either Visio or pdf files here by the due date.
the process details are provided in the case in the pictures
. Here are some hints.
Requirement 1: a level 0 DFD for order processing – You should end up with 4 processes 1.0, 2.0, 3.0 and 4.0.

You are the systems analyst for the Wee Willie Williams
Widget Works (also known as Dub 5). Dub 5 has been
producing computer keyboard components for more
than 20 years and has recently signed an exclusive
10-year contract to provide the keyboards for all Dell
and HP personal computers. As the systems analyst, you
have been assigned the task of documenting Dub 5’s
order-processing system.
Customer orders, which are all credit sales, arrive
via e-mail and by phone. When an order is processed,
a number of other documents are prepared. You have
diagrammed the overall process and the documents pro-
duced, as shown in the context diagram shown below.
The following documents are created:
Order processing creates a packing slip, which the
warehouse uses to fill the order.
• A customer invoice is prepared and sent once the
goods have been shipped.
When orders are not accepted, an order rejection
is sent to the customer, explaining why the order
cannot be filled.
• A receivables notice, which is a copy of the cus-
tomer invoice, is sent to the accounting department
so accounts receivable records can be updated.
After reviewing your notes, you write the following nar-
rative summary:
When an order comes in, the order-processing clerk
checks the customer’s credit file to confirm credit
approval and ensure that the amount falls within the
credit limit. If either of these conditions is not met,
the order is sent to the credit department. If an order
meets both conditions, the order-processing clerk
enters it into the system on a standard order form.
The data on the form is used to update the compa-
ny’s customer file (in which the name, address, and
other data are stored), and the form is placed in the
company’s open order file.
When the credit department receives a rejected
order, the credit clerk determines why the order has
been rejected. If the credit limit has been exceeded,
the customer is notified that the merchandise will
be shipped as soon as Dub 5 receives payment. If
the customer has not been approved for credit, a
credit application is sent to the customer along with
a notification that the order will be shipped as soon
as credit approval is granted.
Before preparing a packing slip, the system
checks the inventory records to determine whether
the company has the products ordered on hand. If
the items are in stock, a packing slip is prepared
and sent to the warehouse.
Once notification of shipped goods has been
received from the warehouse, a customer invoice
is prepared. A copy is filed by the order-processing
department, another is sent to the customer, and
another is sent to the accounting department so
that accounts receivables can be updated. A note
is placed in the customer file indicating that the
invoice has been sent.
From the information presented, complete a Level
O DFD for order processing, a Level 1 DFD for the
credit review process for Dub 5, and a BPD for order
processing.
