Boni Wholesalers Ltd. Provides a variety if goods to customers in Nairobi. The wholesale business is owned and managed by Mr. Boniface Ndambuki. Mr. Boni purchases goods on credit from his well established suppliers. He has a large box-file containing supplier details and another equally large one containing commodity details. The commodity file also indicates the levels of inventory held in the store.
When a customer makes his order, the sales office accesses the commodity file to check if there is sufficient stock of the required items. If there is sufficient stock, then the sales office prepares a delivery note which is forwarded to the accounts office where an invoice is prepared. The invoice and the delivery note accompany the goods from the store to the customer who prepares a payment cheque for Boni Wholesalers Ltd. A copy of the delivery note is filed in the commodity file which now shows that the stock has reduced by the amount delivered to the customer.
Sometimes the stock of the required item is not sufficient to service the customer order. In this case the supplier‟s file is accessed to select the supplier that Boni
Wholesalers Ltd. Will order from. The sales office then produces purchase orders and dispatches them to the selected supplier. The supplier prepares his own invoice and delivery note which accompany the ordered goods to the stores of Boni Wholesalers Ltd. Once received, the invoice is forwarded to the accounts office for payment to the supplier. The delivery note is used to update the commodity as well as the supplier details files.
Required: a) In what ways can a business organization be considered as a system? Derive illustrations from Boni Wholesalers.
