Introduction Manufacturing Organizations are complex `Systems' where the interactions between the various functions Sales, Distribution, Manufacturing, Materials, Finance, Human Resources, Maintenance have to be managed towards a common purpose of delivering the customers maximum value at the optimum price. However, since most of these organizations have a `Functional Structure', each function/department works towards their own goals and objectives, rather than the organizational goals. These are the issues addressed by `Enterprise Resource Planning' software solutions providing a common, consistent system to capture data organization wide, with minimum redundancy.
What is ERP? ERP integrates the information across functions, and provides a set of tools for planning and monitoring the various functions and processes and ensuring progress towards a common purpose A business management system that integrates all facets of the business, including planning, manufacturing, sales, and marketing. ERP helps business managers to implement ERP in business activities such as inventory control, order tracking, customer service, finance and human resources

In 1972 five engineers in Mannheim, Germany, started up SAP (Systemanalyse und Programmentwicklung). The purpose of the company was to produce and market standard software for integrated business solutions.
The term Enterprise resource planning (ERP) was coined in the early 1990 s by the Gartner Group (Wylie, 1990). Their definition of ERP included criteria for evaluating the extent that software was actually integrated both across and within the various functional

Some Questions What are the major types of systems in a business? What role do they play? How do information systems support the major business functions? Why should managers pay attention to business processes?
Major Types of Systems • Executive Support Systems (ESS) • Decision Support Systems (DSS) • Management Information Systems (MIS) • Knowledge Work Systems (KWS) • Office Systems • Transaction Processing Systems (TPS)
Transaction Processing Systems (TPS): • Basic business systems that serve the operational level • A computerized system that performs and records the daily routine transactions necessary to the conduct of the business
Types of TPS Systems
Payroll TPS
Executive Support System (ESS): Strategic level Inputs: Aggregate data Processing: Interactive Outputs: Projections Users: Senior managers Example: 5 -year operating plan
Management Information System (MIS): Management level Inputs: High volume data Processing: Simple models Outputs: Summary reports Users: Middle managers Example: Annual budgeting
Decision Support System (DSS): Management level Inputs: Low volume data Processing: Interactive Outputs: Decision analysis Users: Professionals, staff Example: Contract cost analysis
Knowledge Work Systems (KWS): Knowledge level Inputs: Design specs Processing: Modeling Outputs: Designs, graphics Users: Technical staff and professionals Example: Engineering work station

A supply chain is characterized by the flow of materials and information both within and between business entities including suppliers, manufacturers and customers. The ultimate goal of supply chain management is to meet customer’s demand more efficiently. For a manufacturing company, it is to make the right product, for the right customer, in the right amount, at the right time.
ERP System Options and Selection Methods Enterprise resource planning systems are very large IS/IT projects. The cost range is enormous, depending upon the size of the firm implementing the system , as well as on how many modules are used.
ERP Implementation And Maintenance ERP Systems Are Adopted In The Hopes That They Will Improve The Performance Of An Organization On A Number Of Key Performance Indicators , Such As Profitability , Efficiency , And Accuracy In Information System Data And Reports. ERP Vendors Typically Promise Gains Of 10 To 15 Percent In Revenue , Customer Satisfaction , And Other Measures Of Value. The Effort Required To Build These Systems Is Significant. Meta Group found that the average ERP implementation takes 23 months with total Ownership cost of $15 million.
Business Intelligence Systems And ERP Enterprise Resource Planning Systems Offer Powerful Tools To Better Measure And Control Organizational Operations. Many Organizations Have Found That This Valuable Tool Can Be Enhanced To Provide Even Greater Value Though The Addition Of Powerful Business Intelligence Systems. Business Intelligence In This Context Is Supported By Sorting Data (Data Warehouse And Related Systems) And Conducting Studies Using This Data To Solve Business Problems ( One Means To Do This Though Data Mining ). One Of The Most Popular Forms Of Data Mining In ERP Systems Is Support Of Customer Relationship Management (CRM). Data Warehouses Are One Of The Most Popular Extensions To ERP Systems , With Over Two-Thirds Of U. S. Manufacturers Adopting Or Planning Such Systems ( And Slightly Less Than Two – Thirds of Swedish Manufacturers doing the same ). There Has Been Tremendous Progress In Computer Storage Of Data. Many Applications Are Being Found For This new capacity. one major user of massive storage capacity is ERP systems, witch have large storage requirements due to their comprehensive nature.
Data Mining Overview Refers To The Analysis Of The Large Quantities Of Data Stored In Computers. For Example , Grocery Stores Have Large Amounts Of Data Generated By Purchases. Bar Coding Has Made Grocery Checkout Very Convenient. Grocery Stores And Other Retail Stores Are Able To Quickly Process Purchases , And Use Computers To Accurately Determine Product Prices. These Same Computers Help The Stores With Inventory Management By Instantaneously Determining The Quantity Of Items Of Each Product On Hand. Stores Can Also Apply Computer Technology To Contact Their Vendors So That They Do Not Run Out Of Items. Computers Allow The Store’s Accounting System To More Accurately Measure Costs And Determine The Profit That Store Stockholders Are Concerned About. All Of This Information Is Available Based Upon The Bar Coding Information Attached To Each Product. The Benefits Of Bar Coding Encompass For More Than Faster Checkout Service. The Entire Business Management Process Can Use The Information Generated.
ERP And Supply Chains Supply Chain Are Collections Of Organizations That Work Together To Provide Raw Materials That Are Converted Into Products And Delivered To Retail Outlets Where Customers Can Obtain Them. In The Past , Monopolies Would Sometimes Seek Vertical Integration So That They Could Control The Entire Supply Chain ( Standard Oil Went A Long Way Toward Total Vertical Integration ; Steel Companies Also Attained At Lest Something Approaching It ). The Dutch East India Companies Are An Early Example Of A Global Supply Chain. Military Logistics Systems Are The Epitome Of Supply Chain Is Control And Efficiency. Today‘S Companies Gain Efficiency Through A Higher Degree Of Specialization. This Appears In Various Forms , Including Outsourcing. The Idea Behind Outsourcing Is That There Are Specialists Throughout The Supply Chain Who Can Do A Better Job Of The Specific Function They Perform.
