What is a form of computer-to-computer communication enabling the sharing of business documents?

Electronic Data Interchange (EDI) is a standardized method for exchanging business documents and data between companies using a computer-to-computer communication system. It allows various organizations to automate the exchange of information such as purchase orders, invoices, shipping notices, and other business transactions without the need for human intervention.

The significance of EDI lies in its ability to improve operational efficiency by reducing errors associated with manual entry, accelerating transaction times, and lowering costs related to paper and postage. By adhering to established standards (such as ANSI X12 or EDIFACT), different companies can communicate seamlessly, regardless of their internal systems or software configurations.

While the other options pertain to certain aspects of procurement or cost management, they do not specifically represent a system established for the direct electronic exchange of documents between businesses. Electronic Requests for Quotes (eRFQs) relates to soliciting bids electronically, E-purchasing focuses on the online procurement process, and External Failure Costs refer to expenses incurred when a product fails to meet quality standards after it has been delivered to customers. Thus, EDI stands out as the clear choice for enabling document sharing between computers.
