  2. Managerial Questions • What is ERP? • How will it help my business? • What are its costs? • What are the risks?

  3. 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

  4. What is an ERP? • Links business processes • Maintains audit trail • Utilizes a common information system • Implementation normally involves BPR: Business Process Reengineering • Difficult to Implement Correctly – Railroad Tracks

  5. Before/After ERP

  6. Evolution of ERP • 1960’s: Inventory Control Systems • 1970’s: MRP: Material Requirement Planning • 1980’s: MRPII: MRP & Distribution • 1990’s: MRPII  ERP with introduction of other business functions  CRM’s • Today: Web Enabled ERP – Connecting ERP Externally

  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; world’s 3rd largest software company! • 12 million users, 36,000 customers, 100,600 installations, 1,500 partners world-wide

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

  10. Other SAP Modules • Portals • Supply chain/Supplier relationship management • Customer relationship management • Product life cycle • 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)

  15. ERP Enterprise Architecture

  16. 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 Source: CIO.com: "The ABCs of ERP"

  19. Expenditure Amount (millions) Percentage Hardware 1.46 13.8 Software 1.86 17.5 Internal Staff 2.46 23.2 Professional Services 4.82 45.5 Costs of ERP (cont’d) Average Cost To Install ERP Source: CIO Magazine Oct. 15, 1999

  20. Benefits of ERP - Promised • Shorter order cycle time • Increased productivity • Lower IT costs • Better cash management • Reduced personnel

  21. Benefit Expected Actual Shorter cycle time 19% 31% Improved productivity 24% 31% Lower IT costs 24% 11% Better cash management 24% 13% Personnel reduction 43% 33% 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 (cont’d) • 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).
