Strategic Impact of EDI
Business processes can become more efficient
Customer-supplier relationships may change more trust and collaboration
Market structure changes

Definition of EDI
The direct computer-to-computer transfer of business information between two businesses that uses a standard format.
Focus on trade data interchangeOften use VANs (Value-added
networks)Use of standards

EDI Standards
Companies speak precisely the same language
Same codes in same placesProprietary codes --> to
standards (X12, EDIFACT,X400)Different computers can
communicate with one another

EDI Standards In 1968, the Transportation Data Coordination
Committee was formed, charged with exploring ways to reduce the paperwork burden
American National Standards Institute (ANSI): coordinating body for standards in the United States since 1918
Accredited Standards Committee X12 (ASC X12) chartered by ANSI in 1979 to develop EDI standards
The current ASC X12 standard includes specifications for several hundred transaction sets

Types of EDI Benefits
DirectProcess
require reengineering can only be realized with all trading partners are on EDI
can revolutionize the way business is done

Barriers to Adoption
Trading partners not knowing benefits
Hardware costsInterfacing translator, software costsNeed for software modificationsNetwork (VAN) service chargesCosts and effort for trading partner
conversion

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 11: Electronic Data Interchange (EDI) and SCM zDefine Electronic Data Interchange zGive characteristics of EDI zDiscuss benefits of EDI, as well as barriers.](https://reader035.fdocuments.us/reader035/viewer/2022071806/56649db35503460f94aa3452/html5/thumbnails/11.jpg)
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 12: Electronic Data Interchange (EDI) and SCM zDefine Electronic Data Interchange zGive characteristics of EDI zDiscuss benefits of EDI, as well as barriers.](https://reader035.fdocuments.us/reader035/viewer/2022071806/56649db35503460f94aa3452/html5/thumbnails/12.jpg)
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
![Page 13: Electronic Data Interchange (EDI) and SCM zDefine Electronic Data Interchange zGive characteristics of EDI zDiscuss benefits of EDI, as well as barriers.](https://reader035.fdocuments.us/reader035/viewer/2022071806/56649db35503460f94aa3452/html5/thumbnails/13.jpg)
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 14: Electronic Data Interchange (EDI) and SCM zDefine Electronic Data Interchange zGive characteristics of EDI zDiscuss benefits of EDI, as well as barriers.](https://reader035.fdocuments.us/reader035/viewer/2022071806/56649db35503460f94aa3452/html5/thumbnails/14.jpg)
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 15: Electronic Data Interchange (EDI) and SCM zDefine Electronic Data Interchange zGive characteristics of EDI zDiscuss benefits of EDI, as well as barriers.](https://reader035.fdocuments.us/reader035/viewer/2022071806/56649db35503460f94aa3452/html5/thumbnails/15.jpg)
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
Takes advantage of open architecture

Comparison of EDI Standards EDI STANDARDS
(ASC/ANSI)
Security provided by private networks
EFT (Electronic Funds Transmission) - standard for wire payments between client and vendor
Transactions sets (810-invoices;850, 855- POs)
INTERNET STANDARDS
SSL (Secure Sockets Layer)
SET (Secure Electroic Transactions) - protocol proposed by Visa/MC for Net
No transaction standards

Current Internet EDI Usage
Much EDI traffic carried over private networks scalability reliability processing power
in 1996 EDI Group study 85% of respondents using some form of EDI only 3-4% were using Internet EDI

Changes on the HorizonS/MIME protocol which enables e-mail
applications to verify transmission and receipt of EDI messages
Products to map Web EDI transactions sent in multiple formats to legacy EDI applications
New (but potentially competing) technologies XML OBI

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
