Title: Electronic Data Interchange EDI and SCM


1
Electronic Data Interchange (EDI) and SCM
  • Define Electronic Data Interchange, Exchange
  • Give characteristics of EDI
  • Discuss benefits of EDI, as well as barriers to
    its implementation
  • Describe how EDI works, and how it is moving to
    the Internet
  • Contrast common (ANSI/ASC) EDI with Internet EDI
    and Exchanges

2
Electronic Data Interchange (EDI)
  • Strategic Impact of EDI
  • Definition of EDI
  • Example of EDI
  • How EDI works
  • Benefits of EDI
  • Direct and Process
  • Barriers to EDI Adoption
  • Advantages, Disadvantages and Characteristics of
    VANs
  • EDI Implementation Model
  • EDI migration to the internet

3
Strategic Impact of EDI
  • Business processes can become more efficient
  • Customer-supplier relationships may change
  • more trust and collaboration
  • Market structure changes

4
Definition of EDI
  • The direct computer-to-computer transfer of
    business information between two businesses that
    uses a standard format.
  • Focus on trade data interchange
  • Often use VANs (Value-added networks)
  • Use of standards

5
EDI Standards
  • Companies speak precisely the same language
  • Same codes in same places
  • Proprietary codes --gt to standards (X12,
    EDIFACT,X400)
  • Different computers can communicate with one
    another

6
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

13
Types of EDI Benefits
  • Direct
  • Process
  • require reengineering
  • can only be realized with all trading partners
    are on EDI
  • can revolutionize the way business is done

14
Direct Benefits of EDI
  • Eliminated/reduced paper work
  • Greater accuracy
  • Shorter lead times
  • Less inventory costs
  • More responsiveness to customer
  • Reduced postage
  • Easier product comparison

15
Process Benefits of EDI
  • No redundant clerical tasks
  • Fewer steps to process business documents
  • No redundant information exchanges
  • Reengineered operations
  • Promotes true partnerships

16
Examples of EDI Benefits
  • AIAG - Automakers save 200 per car
  • A large computer manufacturer reduced purchase
    order cycle from 7 to 2 days
  • A supermarket chain eliminated 600 invoice
    errors/day (6,000/day savings)
  • The US Treasury plans to save 50 Million per
    year in postage
  • Dofasco saves 70,000 annually sending 400 ship
    notices and chemistry reports over a secure
    extranet.

17
Barriers to Adoption
  • Trading partners not knowing benefits
  • Hardware costs
  • Interfacing translator, software costs
  • Need for software modifications
  • Network (VAN) service charges
  • Costs and effort for trading partner conversion

19
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

20
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

21
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
  • From 95 of all EDI traffic in 1997 to 50 in 2002

22

23
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

24
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

25
Electronic Data Transmission Migration
26
Internet EDI
  • First waveuse of internet to send EDI
    transaction set data to and from a VAN
  • Second wavetransmission of EDI transaction set
    data over public Internet
  • Third wavetransmission of electronic data over
    public/private internet

27
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

28
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

29
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

31
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-invoices850, 855- POs)
  • INTERNET STANDARDS
  • SSL (Secure Sockets Layer)
  • SET (Secure Electroic Transactions) - protocol
    proposed by Visa/MC for Net
  • No transaction standards

32
Changes on the Horizon
  • S/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
  • XML
  • Exchanges
  • Vertical
  • Horizontal

33
Definition Exchange
  • Web-based real-time transaction systems
    characterized by industry-specific alliances,
    standard-setting bodies and marketplaces.

34
Products to Smooth EDI Wrinkles
  • GEISs TradeWeb - an entry-level forms-based
    service with which subscribers can send up to 30
    EDI documents a month over the Internet using a
    standard Web browser for flat fee (75/mo) (and a
    35 initiation fee)
  • PO, PO acknowledgement, Invoice, Functional
    acknowledgement
  • GEISs services available in English, French,
    German and Italian
  • GEISs Trading Process Network for posting
    EDI-based forms on the Web

35
Products to Smooth EDI Wrinkles (Light EDI)
  • Other Vans with Internet Browser Interfaces
  • http//www.simplix.com
  • Simplex - 200 registration fee and 75/mo
  • http//www.bid-search.com/cedis
  • Creative EDI Solutions - 50 registration fee and
    service charge (min. 15 with 4 transactions)

36
Financial EDI
  • A trading partners 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
