This chapter discusses interorganizational and global information systems. It defines interorganizational systems as those that support information flow between two or more organizations. It also discusses how global information systems connect companies across borders and some of the issues in designing them, such as cultural and legal differences. The chapter then covers specific topics like business-to-business exchanges, electronic data interchange, extranets, and implementation challenges for interorganizational systems.

5. 9.1 Interorganizational Systems (IOSs)
 An information system that supports
information flow among two or more
organizations.
 IOSs have developed in direct response to
two business pressures (drivers): the desire
to reduce costs and to improve the
effectiveness and timeliness of business
processes.

11. Characteristic and problem along
global supply chains
Global supply chains involve supplier and /or
customers in other countries. Some of the
issues in global supply chains are:
 legal issues,
 customs fees and taxes,
 language and cultural differences,
 fast changes in currency exchange rates and
 political instabilities.

12. 9.3 B2B Exchanges and Hubs
Two IT innovations that help organizations
communicate, collaborate and trade are B2B
exchanges and Hubs.
 B2B exchanges can be either private (one buyer
and many sellers, or one seller and many buyers)
or public (many seller and buyers).
 Hub is used to facilitate communication and
coordination among business partners,
frequently along the supply chain.

17. Major Components of EDI
EDI translators
Business transactions messages
Data formatting standards
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 9 17

18. The Process of EDI
The process of EDI:
 Computers talk to computers
 Message are coded using the standards
using a converter
 The massage travels over a Van or the
Internet
 When received the message is automatically
translated into a business language
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 9 18

19. The Benefits of EDI
The benefits of this process are :
Data entry errors are minimized
The length of the message can be shorter
The messages are secured
EDI fosters collaborative relationships
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 9 19

20. Other Benefits of EDI
Reduced cycle time
Better inventory management
Increased productivity
Enhanced customer service
Minimized paper usage and storage
Increased cash flow
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 9 20

21. Internet-Based EDI
Why?
 Accessibility
 Reach
 Cost
 Use of Web technology
 Ease of use
 Added functionality
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 9 21

22. 9.6 Extranets, XNL, and Web Services
Extranet: A network that links business partners to one
another over the Internet by providing access to certain
areas of each other’s corporate intranets.
XLM (eXtensible Markup Language): A simplified
version of the general data description language,
SGML; used to improve compatibility between the
disparate systems of business partners by defining the
meaning of data in business documents.
Web services: Universal, prefabricated business
process software modules, delivered over the Internet,
that users can select and combine through almost any
device enabling disparate systems to share data
services.

23. XML Differ from HTML
 The purpose of HTML is to help build web
pages ad display data on web pages.
 The purpose of HTML is to describe data and
information . It dose not say how the data will
be displayed .
 XML can be used to send complex message
that include different files.
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 9 23

24. Benefits of XML over HTML
 Flexibility
 Understandability
 Less specialized
“ Copyright 2005 John Wiley & Sons Inc.” Chapter 9 24

25. IOS Implementation issues
Partner relationship management (PRM):
all of the efforts made to apply customer
relationship management (CRM) to
relationship with business partners.
Supplier relationship management (SRM):
All of the efforts made to apply CRM to
relationships with suppliers.
Collaborative commerce (c-commerce):
non-selling/buying electronic transaction
between and among organizations.

26. Some Areas of Collaboration Using IOSs
Retailer- suppliers
Product design
Collaborative manufacturing
