Fundamentals of Business Information Systems
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

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
4

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.
