do you have idea what the steps with this diagram assignment?

Scenario You are the systems analyst for the Wee Willie Williams Widget Works (also known as Dub 5). Dub 5 has been producing motors for small appliances for more than 15 years. As the systems analyst, you have been assigned the task of documenting Dub 5's order-processing system. Dub is a wholesaler, that is it sells only to other businesses and not directly to consumers. All customer orders are credit sales and arrive via Dub 5's website or from Sales Rep sales at trade shows. When an order is processed, a number of other documents are prepared. You have diagrammed the overall process and the documents produced, as shown in the context diagram shown below. The following documents are created: . Order processing creates a picking ticket, 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 customer invoice, is sent to the accounting department so accounts receivable records can be updated
