ENTERPRISE-WIDE INFORMATION SYSTEMS
Chapter 7
7-2
SYSTEM CATEGORIES
Enterprise-wide Systems aka Enterprise Systems, are systems that allow companies to integrate information across operations on a company-wide basis
Interorganizational Systems (IOS)Systems that communicate across organizational boundaries whose goal it is to streamline information flow from one company to another
7-3
THE VALUE CHAIN – INTERNALLY FOCUSED
Used to identify the flow of information through a set of business activities. It identifies two types of activities: primary and support.
7-4
THE VALUE CHAIN - PRIMARY ACTIVITIES
Functional areas within an organization that process inputs and produce outputs. These activities may vary widely based on the unique requirements of a company’s industry
Functional areas within an organization that process inputs and produce outputs. These activities may vary widely based on the unique requirements of a company’s industry
Primary Activities include:• Inbound Logistics – receiving and stocking raw materials,
parts, products• Operations/Manufacturing – processing orders and raw
materials into finished product• Outbound Logistics – distribution of the finished product to
customers • Marketing and Sales – creating demand for the product (pre-
sales activities)• Customer Service – providing support for the product or
customer (post-sales activities)

THE VALUE CHAIN - SUPPORT ACTIVITIES
Support activities are business activities that enable Primary Activities. These activities can be unique by industry but are generally more typical across industries.
Support activities are business activities that enable Primary Activities. These activities can be unique by industry but are generally more typical across industries.
Support Activities include:
• Infrastructure – hardware and software that must be implemented to support applications for primary activities
• Human Resources – employee management activities: hiring, interview scheduling, and benefits management
• Technology Development – the design and development of applications that support the organization
• Procurement – purchase of goods or services that are required as inputs to primary activities

7-6
A VALUE SYSTEM – EXTERNALLY FOCUSED
• A connection of value chains across organizations• Allows the flow of information between organizations to
support business activities• Upstream flow is information received from another
organization• Downstream Flow is information sent to another organization

OPTIONS FOR ENTERPRISE SYSTEMS – PACKAGED VS. CUSTOM
Packaged Applications “Off-the-Shelf” computer applications purchased from a vendor or the company that created the system (i.e. Quicken or MS Money for financial applications)

ENTERPRISE SYSTEMS - LEGACY SYSTEM EXAMPLE
Legacy (stand-alone) Systems – information is not readily shared between systems (i.e. Inbound Logistics inventory information shared with Operations)
7-11
ENTERPRISE RESOURCE PLANNINGIntegrated Packages (Enterprise Resource Planning)Richly functional systems designed to support many organizational functions (e.g. accounting and finance)
Integrated Packages (Enterprise Resource Planning)Richly functional systems designed to support many organizational functions (e.g. accounting and finance)
ERP Key Characteristics• Internally focused systems designed to support the internal
operations of the organization• Highly integrated systems sharing a common data warehouse for
information sharing across functions, using real-time updates • Organizational fit may be less for individual departments but the
integrated sharing of information usually outweighs these issues• Usually packaged applications supported by the vendor utilizing a
common user interface• Customization is discouraged but these systems have the
flexibility to support other outside applications using the common data repository and interfaces

ENTERPRISE SYSTEMS – INTEGRATED SYSTEM EXAMPLE
Integrated Systems – Information is stored in a single data repository and can be accessed and updated by all functional systems (e.g. Operations)

CHOOSING AN ERP SYSTEM - ISSUES
ERP Systems are: •Supplied by multiple vendors including SAP, Baan,
Oracle, etc., with each having their own unique features and structures
•Packaged systems that follow a one-size-fits-all strategy which means they may not support all functions as well as a custom system does
•Similar but are also different. They should be selected based on factors including control, business requirements, and best practices

CHOOSING AN ERP SYSTEM – SELECTION FACTORS
Control refers to where the power lies related to computing and decision support systems (centralized vs. decentralized) in selecting systems, developing policies and procedures, etc. (Who will decide?)

Business Requirements refers to the system’s capabilities and how they meet organizational needs through the use of software modules or groups of business functionality (What do you need?)

Best Practices refers to the degree to which the software incorporates industry standard methods for doing business which can cause a need for significant business processes reengineering (How much change is required?)

ERP AND BUSINESS PROCESS REENGINEERING
Hammer and Champy, (“Reenginerring the Corporation”)“The radical redesign of an organization was sometimes necessary in order to lower costs and increase quality and information technology was the key enabler for that radical change.”

Business Process Reengineering
A systematic, structured improvement approach by all or part of an organization whereby people critically examine, rethink, and redesign business processes in order to achieve dramatic improvements in one or more performance measures (e.g. quality, cycle time, cost)

EXAMPLE OF BPR
a retail service company, not a manufacturing company
new process, meat, beans, corn shells, lettuce, tomatoes and cheese for their products are prepared outside of the restaurant in central commissaries
greater quality control, better employee morale, fewer employee accidents and injuries (due to preparation task off-site), big savings and more time to focus on the customer business processes
from a $500 million regional company to a $3 billion national company

BUSINESS PROCESS REENGINEERING
Steps in Business Process Reengineering
• Develop a vision for the organization that specifies business objectives (e.g. reduced costs, shorter time to market, improved quality, etc.)
• Identify critical processes that are to be redesigned
• Understand and measure the existing processes as a baseline for future improvements
• Identify ways that information technology can be used to improve processes
• Design and implement a prototype of the new process(es)

BPR TODAY – OBSERVATIONS AND RESEARCH
Large bodies of research are available on the role of ERP and BPR implementations. Some of this research has come to the following conclusions:
• Reengineering and related organizational issues are as important as the technical implementation issues
• Managers in many cases must choose between making the ERP system fit the organization or the organization fit the ERP system
• For an ERP system to help transform the organization and gain new competitive capabilities, a full organizational and operational change is required
• To be successful, manager must first transform the organization and then implement the ERP system

SUPPLY CHAIN MANAGEMENT BENEFITS
Supply Chain Management applications can help organizations to gain competitive advantage and provide substantial payback in several ways by:
• Streamlining workflow and increasing employee productivity (i.e. efficiently managing business travel, time, and expenses by collaborating with suppliers in real time)
• Accelerating product development (i.e. enabled by the ability of organizations to swiftly react to market conditions)
• Streamlining cost and creating efficiencies across the supply network (i.e., supporting contract negotiation and measuring effectiveness of those agreements)

RECOMMENDATIONS FOR ENTERPRISE SYSTEM SUCCESS
Get Help from Outside ExpertsImplementation success is enabled by deep application experience and access to supporting tools and methods
Take a Multidisciplinary Approach to ImplementationsEnterprise systems span the entire organization and as such require input and participation from all functions
Thoroughly Train UsersTraining in organization, business process, and application functions is critical to success and must be reinforced
Secure Executive SponsorshipThe highest level support is required to obtain resources and make and support difficult reengineering decisions
