Spring 2010 Fundamentals of Business Information Systems

INTRODUCTION TO ENTERPRISE RESOURCE PLANNING SYSTEMS AND SAP

Rationale for ERP System Introduction

Historically, functional areas maintained independent information systems.

Systems not designed to interface with one another.

Information exchange often paper based.

Unified system for data handling should provide efficiencies and permit more effective management.

SAP History

"I think the most profound effect R/3 has had is the general availability of real-time information. Within a company, somebody is fulfilling a task. The task ends. And all information that was affected by this task is available immediately in the new form.

That means you can improve workflow significantly. In conventional organizations, it's a sequential process. You have to pass the work forward. Something changed, and somebody else has to react to that. From the beginning, it was our idea that everyone could do everything at once. You would have access to current information wherever you were and could get everything that you wanted to know. We had to struggle for years on end. People debated this and said that is not the right way of looking at things.

Now that has changed because of the Internet."

Hasso Plattner, CEO, co-chairman, and co-founder of SAP AG Anticipating Change: Secrets Behind the SAP Empire

Discussion

Premise:

ERP software allows a company to unite its information handling.

United information handling mechanisms improve operating efficiency and decision making.

Why aren't all companies using ERP systems?

Work with neighbor(s) and come up with a list of 5 reasons. Make your list as specific as you can.

Key Risk Areas in ERP Implementation

Organizational fit

Skill mix

Management structure and strategy

Software systems and design

User involvement and training

Project management

Critical success factors

Top management support

Implementation team competence

Interdepartmental cooperation and communication

Clear goals and objectives

Effective project management

Reasonable, clear expectations

Critical success factors

Project champion

Vendor support

Careful data handling focus (specification, conversion, etc.)

Adequate resources

User training

Business process reengineering

Customization minimization (Configuration, not customization)

ERP System Return on Investment (ROI)

Cost of ERP implementation highly dependent on company size, number of users, modules selected, and other factors.

Almost always more spent on system installation, implementation, data migration, and training than on software acquisition/licensing.

Meta Group 2002 study: average cost of ERP ownership $15 million.

Wide distribution from $500,000 to $300 million.

Will ROI justify investment?

How can an investment in ERP software pay for itself?

Improved decision making yielding competitive advantage in market.

Improved production efficiency--greater yield with fewer resources.

Improved management of labor cost--dominant manageable business cost.

Reduced inventory risk (obsolescence, spoilage, etc.)

Improved reporting and compliance (reduction of manpower required, improved accuracy and currency)

To understand why we are where we are, it is helpful to study the recent past.

Pre-history of business computing

Early history of business computing

1960s Focus on inventory management and control in production environments

LEO I (Lyons Electronic Office) debuted in 1951. First computer specifically focused on business computing.

Early history of business computing

1970s MRP software debuts to assist in production scheduling and inventory mgmt.

(More) contemporary history of business computing

1980s MRPII expands focus of previous systems into management of entire production process

1990s ERP systems apply same data collection and handling mechanisms organization-wide

Evolution of Business Computing

MRP--Materials Requirement Planning (1970s)

Focuses on resources needed to accomplish scheduled production and when they are needed.

MRPII--Manufacturing Requirements Planning (1980s)

Expanded approach to production planning, incorporating non-production data such as from marketing and finance. (What should be made?)

ERP--Enterprise Resource Planning (1990s)

Expansion of MRPII concepts to all business functions, not just production related. Integrated planning focus. (How can we best operate?)

Enter SAP

SAP pioneered the ERP software market.

Five former IBM employees in Manhheim, Germany founded SAP in 1972.

Goals: Create software that would integrate business

processes.

Make data available interactively and in real time.

Users work with computer screen, not printed output.

SAP Software Timeline

1973 "System R" (real-time data processing) released to market. (Later came to be called "R/1")

1978 "R/2"

ERP System Functional Details

ERP Systems are large-scale applications that run on top of database systems for storage and data management.

SAP typically used with Oracle, DB2, or MS SQL.

Basic SAP installation--over 28,000 tables.

ERP Systems are not "install and go." Configuration required.

Configuration: making the standard software fit your business processes.

SAP: over 8,000 configuration decisions.

ERP Configuration Management--full time job
