Electronic Data Interchange

The computer-to-computer transfer of business information between two businesses that uses a standard format

In the 1950s, companies began to use computers to store and process internal data and information

By the 1960s, companies began exchanging transaction information with each other on punched cards or magnetic tape

Page 9: Purchasing

Electronic Data Interchange

Eventually, trading partners transferred data over telephone lines instead of shipping punched cards or tapes to each other

In 1968, the Transportation Data Coordination Committee was formed, charged with exploring ways to reduce the paperwork burden

Since 1918, the American National Standards Institute (ANSI) became the coordinating body for standards in the United States

Electronic Data Interchange

In 1979, ANSI charted the Accredited Standards Committee X12 (ASC X12) to develop EDI standards

The current ASC X12 standard includes specifications for several hundred transaction sets (the names of the formats for specific business data interchanges)

Electronic Data Interchange

In the mid-1980s, the United Nations Economic Commission for Europe built a common set of EDI standards based on the American model

In 1987, the EDI for Administration, Commerce, and Transport (EDIFACT, or UN/EDIFACT) was developed

Paper-Based Purchasing Process

Paper-based purchasing process results in a paper document created at each information processing step that must be delivered to the department handling the next step

Paper-based transfers between buyer and vendor can be delivered via mail, courier, or fax

EDI Purchasing Process

Mail service is replaced with the data communications of an EDI network

Flows of paper have been replaced with computers running EDI translation software

Value Added Networks

Trading partners can implement the EDI network and EDI translation process in several ways, each using one of two basic approaches

Direct connection Indirect connection

Page 19: Purchasing

19

9

Direct Connection BetweenTrading Partners

Requires each business in the network to operate its own on-site EDI translator computer

EDI translator computers are connected to each other using modems or dedicated leased lines

Trading partners using different protocols can make direct connection options difficult to implement

Page 20: Purchasing

9

Indirect Connection BetweenTrading Partners

Companies use the services of a value-added network (VAN)

The VAN provides communications equipment, software, and skills needed to receive, store, and forward electronic messages containing EDI transaction sets

The VAN often supplies the software needed to connect to its services

Advantages of Using aValue Added Network

Users support only one communications protocol

The VAN records activity in an audit log, providing an independent record of transactions

The VAN can provide translation between different transaction sets

The VAN can perform automatic compliance checks to ensure the transaction set is in the specified EDI format

Page 23: Purchasing

9

Disadvantages of Using aValue Added Network

Most VANs require an enrollment fee, a monthly maintenance fee, and a transaction fee

VANs can be cumbersome and expensive for companies with trading partners using different VANs

Inter-VAN transfers do not always provide a clear audit trail

Page 24: Purchasing

EDI on the Internet

Viewed as a replacement for expensive leased lines and dial-up connections

Small companies can get back in the game of selling to large customers the demanded EDI capabilities of their suppliers

Concerns about security and lack of audit logs continue to be a major roadblock

Page 25: Purchasing

Open Architecture of the Internet

The open architecture of the Internet allows trading partners virtually unlimited opportunities to customize their information interchanges

Page 26: Purchasing

Open Architecture of the Internet

A new ASC X12 Task Group has been charged with several broad objectives Converting the ASC X12 EDI data

elements and transaction set structures to XML, retaining one-to-one mapping

Developing XML data element names consistent with existing ASC X12 transaction sets

Meeting the needs of app-to-app and human-to-app interfaces

A trading partner’s bank is called a Financial EDI (FEDI)

Many trading partners are reluctant to send FEDI transfers for large sums of money over the Internet

Companies may opt to establish an indirect connection through a VAN for the added security for FEDI transaction

Hybrid EDI Solutions

Utilize the Internet for only part of an EDI transaction, ones where the transactions are not considered a negotiable instrument

Bottomline Technologies PayBase package allows hybrid EDI

NetTransact provides an interface for smaller businesses connected to the Internet, but do not have EDI capability

Supply Chain Management

Money can be saved and product quality can be improved through active negotiations with suppliers

Supply chain management is used to establish long-term relationships (supply alliances) with a small number of very capable suppliers (tier one suppliers)

Supply Chain Management

By working together, supply chain members can reduce costs and increase the value of the product or service to the ultimate customer

With clear communication along the supply chain, each participant can know the demands of the ultimate customer and plot a strategy to meet those demands

Page 32: Purchasing

Technology in the Supply Chain

The Internet and the Web can be very effective communication enhancers

Software can allow members to review past performance, monitor current performance, and predict future production levels of products
