Introduction to ERP

History of organizational systems

• Calculation systems• Functional systems• Integrated systems

Calculation systems

• 1950-80• Single purpose• Eliminate tedious human work• Examples: Payroll, General ledger,

Inventory• Technology used: Mainframes,

magnetic tapes, batch processing

Functional systems

• 1975-2000??• Use computers to improve operations• Applications: Human resources, order

entry, manufacturing resource planning• Technologies: Mainframes, PC’s, LAN’s

Minicomputer

Functional systems

• Typically contained within a department• Islands of automation• Applications independently developed

and deployed• Driving force: availability of mini-

computers

Functional system applications

• Human resources System• Accounting and finance systems• Sales and marketing System• Operations management System• Manufacturing Systems

Human Resources

• Recruiting• Compensation• Assessment• Development and Training• Planning

Accounting and Finance

• General Ledger• Financial Reporting• Costing• Budgeting• Accounts Payable• Accounts receivables

Sales and Marketing

• Lead tracking• Sales forecasting• Customer management

Operations

• Order management• Inventory management• Customer service

Manufacturing

• Inventory• Planning

Types of Organizational information Systems

• Administrative systems• Scheduling / Transaction systems• Value oriented systems• Reporting and controlling systems• Analysis and information systems• Planning and decision support systems

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

Solution to disparate systems?

• Integration• Consolidation• Right-sizing• Business Process Redesign• Enterprise wide system

Integrated systems orEnterprise Resource Planning System

ERP - Definition

• ERP is a process of managing all resources and their use in the entire enterprise in a coordinated manner

ERP system: Definition

• ERP is a set of integrated business applications, or modules which carry out common business functions such as general ledger, accounting, or order management

What is ERP?

• Enterprise Resource Planning• Support business through optimizing,

maintaining, and tracking business functions

• Broken down into business processeso HRMo Distribution o Financialso Manufacturing

What makes ERP different

• Integrated modules• Common definitions• Common database• Update one module, automatically

updates others• ERP systems reflect a specific way of

doing business• Must look at your value chains, rather

than functions

Benefits of ERP

• Common set of data• Help in integrating applications for

decision making and planning• Allow departments to talk to each other• Easy to integrate by using processed

built into ERP software• A way to force BPR (reengineering)• Easy way to solve Y2K problem

Vendors

Difficulty in implementation

• Very difficult• Extremely costly and time intensive• Typical: over $10,000,000 and over a

year to implement• Company may implement only certain

modules of entire ERP system• You will need an outside consultant

Common Pitfalls

• Do not adequately benchmark current state

• Did not plan for major transformation• Did not have executive sponsorship• Did not adequately map out goals and

objectives• Highly customized systems to look like

old MRP systems

Survey of ERP implementations

Overview

• 375 IT and business professionals • 52% anticipate budget increases for

new ERP implementations/new modules

• SAP and PeopleSoft/J.D. Edwards were cited as the most popular ERP packages

• 46% indicated that the main challenge to successful ERP implementations was inadequate definition of requirements and resistance to change

How would you characterize your budget for new ERP implementations/new modules deployments FY XXXX compared to your budget in YYYY?

Who is directly responsible for determining your ERP implementations/new modules deployments?

Who are the other key decision-makers/influencers in decisions to add new ERP packages/new modules?

Do you currently have an ERP package?

If your answer is "Yes", which ERP package(s) do you currently use?

Are you considering adding new modules to your existing ERP package?

If your answer is "Yes", which modules are you planning to add?

If you plan to deploy a new ERP package and/or add modules to your existing packages, when would this implementation take place?

Who do you partner with for new ERP implementations and additions of new modules?

What do you see as the main challenges to successful ERP implementations within your organization?
