Introduction
Efficient, integrated information systems are very important for companies to be competitive
An Enterprise Resource Planning (ERP) system can help integrate a company’s operations
Acts as a company-wide computing environment
Includes a database that is shared by all functional areas
Can deliver consistent data across all business functions in real time

Concepts in Enterprise Resource Planning, Fourth Edition
The Evolution of Information Systems
Silos
Information systems configuration used until recently
Companies had unintegrated information systems that supported only the activities of individual business functional areas
Current ERP systems evolved as a result of:
Advancement of hardware and software technology
Development of a vision of integrated information systems
Reengineering of companies to shift from a functional focus to a business process focus

ERP Software Emerges: SAP and R/3
1972: five former IBM systems analysts in Mannheim, Germany formed Systemanalyse und Programmentwicklung (Systems Analysis and Program Development, or SAP)
SAP’s goals:
Develop a standard software product that could be configured to meet the needs of each company
Data available in real time
Users working on computer screens, rather than with voluminous printed output

SAP Begins Developing Software Modules
During their work for German chemical company ICI, Plattner and Hopp had developed the idea of modular software development
Software modules: individual programs that can be purchased, installed, and run separately, but that all extract data from the common database
1982: SAP released its R/2 mainframe ERP software package

SAP R/3
1988: SAP began development of its R/3 system to take advantage of client-server technology
1992: first version of SAP R/3 released
SAP R/3 system was designed using an open architecture approach
Open architecture: third-party software companies encouraged to develop add-on software products that can be integrated with existing software

New Directions in ERP
Late 1990s: Year 2000 (or Y2K) problem motivated many companies to move to ERP systems
By 2000, SAP AG had 22,000 employees in 50 countries and 10 million users at 30,000 installations around the world
By 2000, SAP’s competition in the ERP market:
Oracle
PeopleSoft
Late 2004: Oracle succeeded in its bid to take over PeopleSoft

ERP for Midsized Companies
By 1998
Most of the Fortune 500 companies had already installed ERP systems
ERP vendors refocused their marketing efforts on midsized companies
SAP All-in-One
Single package containing specific, preconfigured bundles of SAP ERP tailored for particular industries
Can be installed more quickly than the standard ERP product

Application hosting
Third-party company provides the hardware and software support
Makes ERP systems like SAP more appealing to midsized companies
SAP and Oracle are facing competition from smaller providers of ERP software

The Significance and Benefits of ERP Software and Systems
More efficient business processes that cost less than those in unintegrated systems
Easier global integration
Integrates people and data while eliminating the need to update and repair many separate computer systems
Allows management to manage operations, not just monitor them
Can dramatically reduce costs and improve operational efficiency

Concepts in Enterprise Resource Planning, Third Edition
Should Every Business Buy an ERP Package?
Size of the firm, budget, data dependence, unique processes, culture, top management’s commitment
Some of a business’s operations, and some segments of its operations, might not be a good match with the constraints of ERP
Sometimes, a company is not ready for ERP
ERP implementation difficulties result when management does not fully understand its current business processes and cannot make implementation decisions in a timely manner

Is ERP Software Inflexible?
Many people claim that ERP systems, especially the SAP ERP system, are rigid
Options for customization offered by SAP ERP
Numerous configuration options that help businesses customize the software to fit their needs
Programmers can write specific routines using Advanced Business Application Programming (ABAP)
Once an ERP system is in place, trying to reconfigure it while retaining data integrity is expensive and time-consuming

How Long Does It Take to See a Return on an ERP Investment?
Return on investment (ROI): assessment of an investment project’s value
Calculated by dividing the value of the project’s benefits by the project’s cost
ERP system’s ROI can be difficult to calculate
Peerstone Research study
63 percent of companies that performed the calculation reported a positive ROI for ERP
Most companies felt that nonfinancial goals were the reason behind their ERP installations

Concepts in Enterprise Resource Planning, Third Edition
Why Do Some Companies Have More Success with ERP Than Others?
Low ROI & bumpy rollouts due to people problems and misguided expectations (not necessarily computer malfunctions)
Misguided expectations: ERP solves fundamental business problems
Role of top management: No enough analysis time spent for planning and implementation
Training: No substantial time /budget for training
No ownership & accountability assignment
No top management sponsorship
Poor change management

Summary
Speed and power of computing hardware increased exponentially, while cost and size decreased
Early client-server architecture provided the conceptual framework for multiple users sharing common data
Increasingly sophisticated software facilitated integration, especially in two areas: A/F and manufacturing resource planning
36
Concepts in Enterprise Resource Planning, Third Edition
Summary (cont’d.)
Growth of business size, complexity, and competition made business managers demand more efficient and competitive information systems
SAP AG produced a complex, modular ERP program called R/3
Could integrate a company’s entire business by using a common database that linked all operations
SAP R/3, now called SAP ERP, is modular software offering modules for Sales and Distribution, Materials Management, Production Planning, Quality Management, and other areas
37
Concepts in Enterprise Resource Planning, Third Edition
Summary (cont’d.)
ERP software is expensive to purchase and time-consuming to implement, and it requires significant employee training—but the payoffs can be spectacular
For some companies, ROI may not be immediate or even calculable
Experts anticipate that ERP’s future focus will be on managing customer relationships, improving planning and decision making, and linking operations to the Internet and other applications through service-oriented architecture
