Problems with function based application
Sharing of data between systems Data duplication Data inconsistency Applications that don’t talk to one another Limited or lack of integrated information Isolated decisions lead to overall
inefficiencies Increased expenses

Legacy Systems
Each department has its own system Infrastructure specific Inefficient processes Potential for inaccuracies

Limitations of Legacy Systems Legacy systems used in large enterprises
of the 1970s and 1980s have limitations. They were developed in-house or by
different vendors using several different DBMSs, languages and packages
Difficult to increase the capacity of such systems or unable to upgrade them with the organization’s business changes, strategic goals and new information technologies

Internally focused systems
Support functional areas, business processes and decision-making within an organization
New information (value) is added at every step

Externally Focused Systems
Coordinate business activities with customers, suppliers, business partners and others who operate outside the organization

The Need for Integrated Enterprise Systems
Advantages of integrated systems Centralized point of access
Conversion needed
Enterprise Resource Planning (ERP) vendors offer different modules Components that can be selectively
implemented E.g., modules of mySAP business suite
![Page 38: Introduction to ERP.ppt](https://reader036.vdocuments.us/reader036/viewer/2022062808/5695cedf1a28ab9b028b968b/html5/thumbnails/38.jpg)
The Rise of Enterprise Systems
Packaged applications Written by third-party vendors Used by many different organizations Useful for standardized, repetitive tasks Cost effective E.g., Microsoft Money and Quicken
Custom applications Developed exclusively for a specific organization Designed for particular business needs Higher development costs
![Page 39: Introduction to ERP.ppt](https://reader036.vdocuments.us/reader036/viewer/2022062808/5695cedf1a28ab9b028b968b/html5/thumbnails/39.jpg)

Introduction
Enterprise Resource Planning: a process of planning and managing all resources and their use in the entire enterprise
ERP System is an enterprise-wide information system designed to coordinate all the resources, information, and activities needed to complete business processes such as order fulfilment or billing.
![Page 41: Introduction to ERP.ppt](https://reader036.vdocuments.us/reader036/viewer/2022062808/5695cedf1a28ab9b028b968b/html5/thumbnails/41.jpg)
ERP Systems Defined (cont.)
“ERP (enterprise resource planning systems) comprises of a commercial software package that promises the seamless integration of all the information flowing through the company–financial, accounting, human resources, supply chain and customer information” (Davenport, 1998).
“ERP systems are configurable information systems packages that integrate information and information-based processes within and across functional areas in an organization” (Kumar & Van Hillsgersberg, 2000).
41
![Page 42: Introduction to ERP.ppt](https://reader036.vdocuments.us/reader036/viewer/2022062808/5695cedf1a28ab9b028b968b/html5/thumbnails/42.jpg)
“One database, one application and a unified interface across the entire enterprise” (Tadjer, 1998).
“ERP systems are computer-based systems designed to process an organization’s transactions and facilitate integrated and real-time planning, production, and customer response” (O’Leary, 2001).
![Page 43: Introduction to ERP.ppt](https://reader036.vdocuments.us/reader036/viewer/2022062808/5695cedf1a28ab9b028b968b/html5/thumbnails/43.jpg)
ERP Objective
To integrate all departments and functions across a company onto a single computer system that can serve all of the enterprise’s needs
For example, improved order entry allows immediate access to inventory, product data, customer credit history, and prior order information
This availability of information raises productivity and increases customer satisfaction

Evolution of ERP
1960’s - Systems Just for Inventory Control
1970’s - MRP – Material Requirement Planning (Inventory with material planning & procurement)
1980’s - MRP II – Manufacturing Resources Planning (Extended MRP to shop floor & distribution Mgnt.)
Mid 1990’s - ERP – Enterprise Resource Planning (Covering all the activities of an Enterprise)
2000 onwards – ERP II – Collaborative Commerce (Extending ERP to external business entities)

ERP: Bringing the Organization Together
ERP – integrates (or integrated set of IT systems) so that employees can make enterprise wide decisions by viewing enterprise wide information on all business operations (enterprise wide information)
Keyword in ERP is “enterprise”
ERP systems focus on all processes, departments and operations for the entire enterprise
![Page 46: Introduction to ERP.ppt](https://reader036.vdocuments.us/reader036/viewer/2022062808/5695cedf1a28ab9b028b968b/html5/thumbnails/46.jpg)
Best Practices-Based Software
Most ERP vendors build best practices into their ERP systems Identify business processes in need of change Future updates are smoother if businesses
change their business processes to fit with ERP systems
Is following the best practices always the best strategy? If companies have competitive advantage
from unique business processes

ERP Systems and Organizations Generally a misleading perception that ERP system
can improve organizations’ functionalities overnight. Achieving all-round cost savings and service
improvements is very much dependent on: how good the chosen ERP system fits to the organizational
functionalities and how well the tailoring and configuration process of the
