What is an ERP?
  • Enterprise-wide system that integrates the
    business functions and processes of an
    organization
  • Integration of business functions into one
    seamless application
  • Usually runs on a relational database
  • Replaces countless departmental and workgroup
    information systems

  • Links business processes
  • Maintains audit trail
  • Utilizes a common information system
  • Implementation normally involves BPR
    Business Process Reengineering
  • Difficult to Implement Correctly Railroad Tracks

Evolution of ERP
  • 1960s Inventory Control Systems

    Planning
  • 1980s MRPII MRP Distribution

7
Factors Along the Path to ERP
  • The development of client-server architecture
  • and later the n-tier client-server architecture
  • The rush to replace out-dated and non-Y2K
    compliant systems.
  • The desire to have integrated systems within the
    firm.
  • The desire to get out of the application
    development "business".

8
SAP An ERP in Profile
  • Flagship products are MySAP ERP and Duet (with
    Microsoft)
  • The largest ERP company in the world worlds 3rd
    largest software company!
  • 12 million users, 36,000 customers, 100,600
    installations, 1,500 partners world-wide

Core Modules of SAP
  • Finance
  • Human Resources
  • Corporate Services (asset management, project
    management, etc.)
  • Operations (manufacturing, sales, service,
    logistics, etc.)

10
Other SAP Modules

  • Business intelligence

11
ERP Vendor Landscape
12
E-business Application Architecture
13
Interfaces
  • The goal in ERP is to sunset as many systems as
    possible
  • But some systems will remain
  • Need to build interfaces these systems
  • More interfaces built/maintained
  • ? more complexity of the ERP implementation
  • ? higher cost.

14
and Bolt-ons
  • Core ERP functions may be augmented by bolt-ons
    (specialized functionality above and beyond that
    of the ERP)
  • Four major areas
  • Supply Chain Management (SCM)
  • Product Lifecycle Management (PLM)
  • Customer Relationship Management (CRM)
  • Business Intelligence (BI)

ERP Enterprise Architecture

How SAP Works
17
Issues with SAP
  • Cultural Issues
  • System designed in North America or Western
    Europe
  • Embodies best practices from home country
    based on home country assumptions
  • Practices and assumptions may not transfer across
    borders

18
Costs of ERP
  • Meta Group survey of 63 companies (small to
    large, range of industries)
  • Average of 15 M per firm (range 400,000 -
    300M)
  • On average the TCO is 53,000 per user
  • Media annual savings 1.6M
  • Requires two-years of implementation and
    integration

21
Benefits of ERP - Actual
Expected and Actual Benefits
22
Reasons to Adopt ERP
  • One face to the customer
  • Knowing what is possible in terms of
    organizational inventory
  • Eliminating redundancy
  • Consolidation

23
Reasons to Adopt ERP (contd)
  • Handle growth
  • Reduce stress on existing IT
  • Avoid legacy systems
  • Modernizing

24
Reasons Not to Adopt
  • Cost
  • Loss of competitive advantage
  • Resistance to change
  • Poor cultural fit

25
Alternatives?
  • Open Source ERP ( Support Vendors)
  • e.g. GNU Enterprise, Apache OFBiz
  • ERP for SMEs
  • less expensive systems with fewer "bells and
    whistles"
  • ERP ASPs (Application Service Providers)
  • ASPs will host and maintain the software for you

26
Post-ERP?
  • Service-Oriented Architectures (SOA) hold some
    promise as the natural evolution from ERP
  • The foundation of SOA is standardization based
    upon web services interoperability standards.
  • SOA does not replace ERP
  • provides the ability to loosely couple services
    (business functions).
