- Information Systems evolution and its historical
role - The need for integrated systems
- ERP basics
- Overview
- Components
- Evolution
- Vendors and Market
- Benefits and drawbacks of implementing ERP systems
3Hershey
- Hersheys first attempt to implement an ERP
system was a failure why? - Hersheys second attempt to implement several
years later was quite successful why? - What does the information in this case tell you
about the nature /characteristics of ERP systems?
4Preview
- In the early days of ERP implementation most
organizations did not understand the magnitude of
issues to consider before, during, and after
implementation. - ERP systems are very different from conventional
packaged software, such as Microsoft Office and
others. - There are no shortcuts when it comes to
implementing an enterprise system.
5Information Systems in Organizations
- Information Systems are a critical component of a
successful organization today. - Information Systems provide a high level of
computer automation to support business functions
such as - Accounting
- Finance
- Marketing
- Customer Service
- Human Resource Management
- Manufacturing
What are some other functions in a business?
6Information Systems in Organizations (Contd)
- Information Technology hardware, software,
communications networks and data. - Information Systems IT procedures people.
- The role of an information system is to process
data into information in order to support people
and the processes they are engaged in.
Comm. Network
Comm. Network
7Basic Functions of all of an Information Systems
Examples What are the inputs, processing and
output for a sales order? A student registering
for a course?
8Information Systems includes procedures and people
9Role of Information Systems in the Enterprise
- Business organizations have become more complex
and specialized many functions. - Each functional area has different information
needs. - Management is generally categorized into three
levels- Strategic, Middle, and Operational. - Each management level has different information
requirements. - No single information system can support all the
business needs of an organization. - .Not even ERP
-
10Management Pyramid with Information Requirements
11Information Silos
- Historically, organizations developed systems to
support individual functions - Over time, this created a hodgepodge of
independent nonintegrated systems - Redundant data entry and data
- Lots of handoff
- Slow
- Poor customer service
- .more on this later
12Needs of a competitive organization
- Organizations need to be agile and flexible
means integrated data, applications, and
resources across the organization. - To compete effectively, organizations have to be
customer focused. - This requires cross-functional integration among
the accounting, marketing, sales, manufacturing,
shipping.. - Traditional systems did not (dont) meet these
13Enterprise Resource Planning (ERP) Systems
- Enterprise Resource Planning Systems are
enterprise systems meant to integrate data and
support many of the major functions of
organizations. - Traditional focus back office
- ERP systems integrate various functions inside
the organizations AND with external partners like
customers and suppliers. - The goal of an ERP system is integrate data and
to make the information flow dynamic and
immediate, therefore, increasing its usefulness
and value.
14Enterprise Resource Planning (ERP) Systems (cont)
- Clients, employees and vendors all use the same
system - Major functions are integrated in a single
software system - Data flows seamlessly
Do you see any issues with sharing data with
customers and vendors?
15Enterprise Resource Planning (ERP) Systems
(Contd)
- Integrate departments and functions across an
organization sharing a common database - Replace an assortment of systems and numerous
databases that typically existed in
organizations. - Integrated information available in real-time.
16ERP Supported Functions
All of these functions. One software package.
One database
17Example of How ERP Works
- Step 1 Brazilian retailer orders, via the
Internet, 1,000 shoes from International Shoe Co.
A sales rep takes the order, routes it to ERPs
ordering module, ERP checks the retailer credit,
price, etc. The order is approved. - Step 2 Simultaneously ERPs inventory module
checks the stocks and notifies the rep that half
the order can be filled immediately from stock.
The other half will be manufactured and delivered
in 5 days directly from the factory in Taiwan.
18Example of How ERP Works
- Step 3 ERPs manufacturing module schedules the
production in Taiwan and instructs the warehouse
(in Chinese) to ship the shoes to Brazil and
print up an invoice (in Portuguese). - Step 4 ERPs human resources module calculates
labor requirements. Due to a shortage, the
personnel manager in Taiwan is instructed to get
temporary workers. - Step 5 ERPs material planning module notifies
the purchasing manager about a shortage of purple
dye. A purchase order is automatically issued.
19Example of How ERP Works
- Step 6 The customer logs on via the extranet to
the companys sneakers division. He can see that
500 shoes were shipped from the regional
warehouse. This is done with ERP tracing
capabilities. - Step 7 Based on data from ERPs forecasting and
financial modules, the CEO can determine both
demand and profitability per product. The
financial module also converts all foreign moneys
to U.S., whenever needed
20Factors in development of ERP
- Speed and power of computing
- Hardware (servers and disk) now cheap and fast
makes ERP feasible - Happened in the 90s.
- Increasingly complex business environment
- Organizational complexity
- Increasingly demanding customers
- Globalization
- Increased competition
- Increasingly sophisticated software needs
- Legacy systems break under the strain of.all
of the above -
21Evolution of ERP
- Material Requirement Planning (MRP). 1970s
- Inventory reordering tool
- Mainframe
- Manufacturing Resource Planning (MRP II). 1980s
- Extended to managing manufacturing process
- Mainframe
- Enterprise Resource Planning (ERP) ..1990s
- Complete back office
- Client - Server
- Web Enabled Supply Chain .2000s
- Extending the capabilities of ERP to customers,
suppliers, distributors etc. - Internet and WWW

23Industry Life Cycle Stages
ERP software industry is here
24ERP Vendors
- Consolidation is currently taking place in the
ERP software business - PeopleSoft purchased ERP vendor J.D. Edwards in
2003 - Oracle, after a long battle, acquired PeopleSoft
in 2005 - SAP and Oracle are now the two largest ERP
vendors - Microsoft is challenging SAP and Oracle to sell
ERP systems to small- and medium-sized businesses - Other vendors
25SAP
- Founded 1972 in Waldorf, Germany
- Largest market share (30 - 60)
- Revenues exceed 5 Billion
- Used by approx. 60 of multinationals
- Fourth largest supplier of software trailing
Microsoft, Oracle and Computer Associates - Over 2.5 million users
- Over 9,000 implementations of R/3 at over 6,000

28E-Business and ERP
29Figure 1-10 eBusiness and ERP
Organizations need effective ERP in order to
implement effective e-Business WHY?
30- How does ERP create value?
- It integrates a broad range of business functions
- It allows diverse enterprises to standardize
- It stops data redundancy and synchronization
- Data stored in one place
- One version of the truth
- It provides simultaneous access to real-time data
- It facilitates communication inside and outside
the enterprise - Allows an organization to reengineer (change)
- It provides a foundation for eBusiness
-
31ERP Drawbacks
- Very expensive
- Risky to implement
- Long time to value
- Forces organizations to change
32Hidden Costs
- Training
- Critical, but effort and cost is often
underestimated - Integration and Testing
- Links between modules and between ERP software
and external systems - Customization
- Expensive, complex, dangerous
- Data Conversion
33Hidden Costs
- Consultants
- Staffing
- Need best and brightest from business how to
replace them? - Implementation team needs to stay in place
- Delayed ROI
- Post-ERP Depression
- All change and upheaval impact on
organizations morale
