  1. Chapter 7Enterprise-WideInformation Systems

  2. Chapter 7 Objectives • Understand how information technology supports business activities • Understand enterprise systems and how they evolved • Understand software applications that are internally or externally focused • Understand how to implement enterprise systems

  3. Enterprise Systems • Enterprise systems • Info. Sys. supports various business activities for internal operations (manufacturing, order processing, human resource management) as well as external interactions with customers, suppliers, and business partners. • However, the problem is they were built on different platforms (mainframe/minicomputer). • Enterprise systems are information systems that allow companies to integrate information across operations on a company-wide basis • Also known as enterprise-wide information systems

  4. Enterprise Systems • Enterprise systems • Rather than storing information in separate places throughout the organization, enterprise systems provide a central repository common to all corporate users. • It provides a common interface and allows personnel to share information seamlessly no matter where the data is located.

  5. Enterprise Systems • Enterprise systems • The emergence of Internet and the Web has resulted in the globalization of customer and supplier networks and opened up a new opportunities and methods to conduct business. • New business needs/expectations: • Higher levels of customer services, faster and efficient product development to compete in global market. • Internally focused systems support functional areas, processes within the organization. These activities can be viewed as a series of links in a chain along which information flows within the organization. At each stage in the process, value is added in the form of the work performed by people associated that process.

  6. Enterprise SystemsInformation flow for an order Information begins to accumulate at the point of entry when a customer sends an order to the company and flows through the various links.

  7. Enterprise SystemsInformation flow for an order • When a customer places an order, the order is entered into an order-entry application. • The information containing the order is sent to the fulfillment department. • Fulfillment department picks the items from inventory, packages them for distribution, and produces packing list. • The package, along with the packing list, is forwarded to the shipping department. • Shipping department coordinates the shipment, produces invoice, and sends the package and invoice to the customer.

  8. Enterprise Systems • Externally focused systems coordinate business activities with customers, suppliers, and business partners who operate outside the organizational boundary. • Systems that communicate across organizational boundaries are called interorganizational systems (IOS).

  9. Enterprise Systems • Interorganizational systems (IOS) • The key purpose of an IOS is to streamline the flow of information from one company’s operations to another’s • It provides electronic transmission of information to another company. • Competitive advantage can be accomplished here by integrating multiple business processes to meet a wide range of unique customer needs. • Sharing information between organizations helps companies to adapt more quickly to changing market conditions.

  10. Information flow across organizational boundaries

  11. Information flow across organizational boundaries • When a company places an order for components, the supplier performs the shipping activity. The supplier delivers a physical package and electronic invoice to the customer. • The customer’s receiving department takes the delivery and verifies the invoice. Then the receiving department stocks the items in the inventory and updates the inventory level.

  12. Value chain framework

  13. Enterprise Systems • Internally Focused Applications • Value chain – the set of business activities • Functional areas can be broken down into primary and support activities. • Primary activities are functional areas within an organization that process inputs and produce outputs. • Support activities are those activities that enable primary activities to take place.

  14. Enterprise Systems • Internally Focused Applications • Primary activities include: • Inbound logistics • Operations and manufacturing • Outbound logistics • Marketing and sales • Customer service

  15. Enterprise Systems • Internally Focused Applications • Support activities include: • Infrastructure (hardware & software) • Human resources (hiring, interview scheduling, payroll, benefits) • Technology development (software selection, Internet, intranet, extranet) • Procurement (purchasing of goods and services required as inputs primary services)

  16. Enterprise Systems • Externally Focused Applications • Integrate internal applications with those outside: suppliers, partners, customers • Upstream information • Information received from another organization • Downstream information • Information sent to another organization

  17. Value system framework

  18. Types of Enterprise Systems • Packaged applications • Custom applications • Stand-alone applications

  19. Types of Enterprise Systems • Legacy Systems • Older systems • Tend to be infrastructure-specific • Usually linked to a specific business need • Not integrated

  20. Types of Enterprise Systems • Enterprise Resource Planning • Integrated applications • ERP systems • Baan • Oracle • PeopleSoft • SAP • J.D. Edwards

  21. Types of Enterprise Systems • ERP Implementation • Modules • “Vanilla” version • Customizations • Best practices • Business process reengineering (BPR)

  22. Types of Enterprise Systems • Customer Relationship Management (CRM) • Sales Force Automation (SFA) • New opportunities for competitive advantage • Examples: • MGM • American Airlines • Marriott International

  23. Types of Enterprise Systems • Supply Chain Management (SCM) • Supply chain – the producers of supplies that a company uses • Supply network • What if supply chain does not collaborate? • Two objectives of upstream information flow: • Accelerate product development • Reduce costs associated with suppliers

  24. The Formula for Enterprise System Success • Secure executive sponsorship • Get help from outside experts • Thoroughly train users • Take a multidisciplinary approach to implementation
