Draw a cause-effect diagram to explain the invoice errors. Please genuine work and no copy and paste from anywhere. Thank you.

Case Study: The Problem Is in the Bag (20 min.) Bagit Company is a major producer of shopping bags. It produces and distributes both paper and plastic bags to be used mostly by supermarkets and hardware stores. During the last two months, the company has begun a major effort to improve the quality of its products as well as its service to customers. Among the problems that surfaced were a number of complaints by customers about errors on invoices for goods sent out by Bagit. The preliminary data, assembled by a team formed to address this issue, indicates that about 8 percent of customers have notified the company of errors. Although the data is not sufficient for a complete analysis, it appears that some of the major problems relate to errors in the quantities for items billed; errors in pricing, and customers being billed for items never sent to them. The problem is serious, and a clear understanding of its causes needs to be established. The team has decided to prepare a C-E diagram to capture all the possible reasons for these errors in the invoices. It can then design a method to collect the data it needs to establish the root causes. The team has prepared a high-level flow diagram of the sequence of events leading to shipping and invoicing as follows: On the basis of the customer order, the customer invoice is sent to the Shipping Department. The Shipping Department prepares the shipment according to availability in the warehouse at that time. The Problem is in the Bag (cont.) If the quantity or type of product requested by the customer is not available on that day, the Shipping Department requests, via computer terminal, a new invoice for the available items and a back-order position for the items and/or quantities not available. The shipment is prepared and sent out by the Shipping Department. The Accounting Department pulls from the system a copy of the invoice to be sent by mail to the customer. In addition, the team noted the following facts: The accounting of customer orders, invoice generation, and warehouse stocks is kept by a new computer system installed only four months before. The actual packaging of the products to be shipped to the customer was done manually by warehouse workers. Because no one had ever before inquired about the number of error complaints by customers, it is possible that the problem was an old one that had been accepted as normal.' It is also possible that the problem had deteriorated during the last few months as a result of some new factors introduced in the company's procedures. On the basis of the information presented above and your knowledge about people, computer systems, warehousing, and perhaps a similar type of operation, prepare a cause-effect diagram to explain the invoice errors. 1
