Why Learn About Electronic and Mobile Commerce and Enterprise Systems?

• Most organizations have an Internet presence– Sales/marketing manager involved with e-commerce– Customer service employees help develop Web site– Human resource or public relations manger may

provide Web content for employees and investors

• Must learn about e-commerce and m-commerce

• Many organizations use enterprise systems to perform business processes and to keep records

• Support various business activities: Supply chain management, customer relationship management


An Introduction to Electronic Commerce

• Electronic commerce: conducting business activities (e.g., distribution, buying, selling, marketing, and servicing of products or services) electronically over computer networks such as the Internet, extranets, and corporate networks

• Business activities that are strong candidates for conversion to e-commerce– Paper-based– Time-consuming – Inconvenient for customers


Business-to-Business (B2B) E-Commerce

• Business-to-business (B2B) e-commerce: subset of e-commerce where all the participants are organizations– Considerably larger and growing more rapidly than

the business-to-consumer market


Business-to-Consumer (B2C) E-Commerce

• Business-to-consumer (B2C) e-commerce: customers deal directly with the organization, avoiding any intermediaries

• Elimination of intermediaries:– Squeezes costs and inefficiencies out of supply

chain– Can lead to higher profits for companies and lower

prices for consumers


Consumer-to-Consumer (C2C) E-Commerce

• Consumer-to-consumer (C2C) e-commerce: participants are individuals, with one serving as the buyer and the other as the seller– eBay: example of a C2C e-commerce site


eGovernment

• eGovernment: use of information and communications technology to simplify the sharing of information, speed formerly paper-based processes, and improve the relationship between citizen and government

• Forms of eGovernment– Government-to-consumer (G2C)– Government-to-business (G2B)– Government-to-government (G2G)


Mobile Commerce

• Mobile commerce (m-commerce) relies on the use of wireless devices, such as personal digital assistants, cell phones, and smart phones, to place orders and conduct business


Mobile Commerce in Perspective

• Market for m-commerce in North America is maturing much later than in Western Europe and Japan– Western European and Japanese consumers are

much more willing to use m-commerce

• Mobile phone gaming in the United States is expected to increase from about $380 million in 2006 to more than $1 billion by 2009


Technology Needed for Mobile Commerce

• Handheld devices used for m-commerce have limitations that complicate their use

• Wireless application protocol (WAP): a standard set of specifications for Internet applications that run on handheld, wireless devices


Electronic and Mobile CommerceApplications: Retail and Wholesale

• Electronic retailing (e-tailing): the direct sale from business to consumer through electronic storefronts, typically designed around an electronic catalog and shopping cart model

• Cybermall: a single Web site that offers many products and services at one Internet location

• Manufacturing, repair, and operations (MRO) goods and services


Manufacturing

• To raise profitability and improve customer service, many manufacturers move their supply chain operations onto the Internet

• Electronic exchange: an electronic forum where manufacturers, suppliers, and competitors buy and sell goods, trade market information, and run back-office operations


Manufacturing (continued)

Figure 5.2: Model of an Electronic Exchange


Marketing

• Market segmentation: the identification of specific markets to target them with advertising messages

• Technology-enabled relationship management: use of detailed information about a customer’s behavior, preferences, needs, and buying patterns to set prices, negotiate terms, tailor promotions, add product features, and otherwise customize the entire relationship with that customer


Investment and Finance

• Online stock trading has brought many investors to the Web

• Online banking– Online bill payment facility

• Electronic bill presentment: a method of billing whereby a vendor posts an image of your statement on the Internet and alerts you by e-mail that your bill has arrived


Auctions

• eBay: synonymous with online auctions for both private sellers and small companies

• Hundreds of other online auction sites cater to newcomers to online auctions and to unhappy eBay customers

• Most frequent complaints– Increases in fees– Unscrupulous buyers


Anywhere, Anytime Applications of Mobile Commerce

• M-commerce devices are ideal for accessing personal information and receiving targeted messages because of having a single user

• Companies can reach individual consumers to establish one-to-one marketing relationships and communicate whenever it is convenient—in short, anytime and anywhere


Advantages of Electronic and Mobile Commerce

An Overview of Enterprise Systems:Transaction Processing Systems and

Enterprise Resource Planning• Enterprise system: a system central to the

organization that ensures information can be shared across all business functions and all levels of management to support the running and managing of a business

• Eliminates the problems of lack of information and inconsistent information caused by multiple transaction processing systems


Transaction Processing Systems andEnterprise Resource Planning (continued)

• Enterprise resource planning systems support supply-chain processes

• Transaction processing systems capture and process detailed data necessary to update records about the fundamental business operations of the organization– Include order entry, inventory control, payroll,

accounts payable, accounts receivable, and the general ledger


Transaction Processing Systems andEnterprise Resource Planning (continued)

Figure 5.5: TPS, MIS/DSS, and Special Information Systems in Perspective


Traditional Transaction Processing Methods and Objectives

• Batch processing system: method of computerized processing in which business transactions are accumulated over a period of time and prepared for processing as a single unit or batch

• Online transaction processing (OLTP): computerized processing in which each transaction is processed immediately, without the delay of accumulating transactions into a batch


Traditional Transaction Processing Methods and Objectives (continued)

Figure 5.6: Batch Versus Online Transaction Processing


Transaction Processing Activities

• TPSs– Capture and process data that describes

fundamental business transactions– Update databases– Produce a variety of reports

• Transaction processing cycle: the process of data collection, data editing, data correction, data manipulation, data storage, and document production


Transaction Processing Activities (continued)

Figure 5.8: Data-Processing Activities Common to Transaction Processing Systems


Data Collection

• Data collection: capturing and gathering all data necessary to complete the processing of transactions

• Data should be:– Collected at source– Recorded accurately and in a timely fashion


Data Editing

• Data editing: the process of checking data for validity and completeness– Example: quantity and cost data must be numeric

and names must be alphabetic; otherwise, the data is not valid


Data Correction

• Data correction: the process of reentering data that was not typed or scanned properly– Example: a scanned UPC code must match a code

in a master table of valid UPCs


Data Manipulation

• Data manipulation: the process of performing calculations and other data transformations related to business transactions– Includes classifying data, sorting data into

categories, performing calculations, summarizing results, and storing data in the organization’s database for further processing


Data Storage

• Data storage: the process of updating one or more databases with new transactions

• After being updated, this data can be further processed and manipulated by other systems and made available for management reporting and decision making


Document Production and Reports

• Document production: the process of generating output records and reports– Hard-copy paper reports– Displays on computer screens (soft copy)


Control and Management Issues: Disaster Recovery Plan

• Disaster recovery plan (DRP): formal plan describing the actions that must be taken to restore computer operations and services in the event of a disaster

• Necessary for preventing a lengthy disruption in the operation of any of a company’s critical business information systems that directly affect its cash flow


Transaction Processing System Audit• Transaction processing system audit: a check

of a firm’s TPS systems to prevent accounting irregularities and/or loss of data privacy

• Attempts to answer four basic questions– Does the system meet the business need for which it

was implemented?– What procedures and controls have been

established?– Are these procedures and controls being used

properly?– Are the information systems and procedures

producing accurate and honest reports?

Enterprise Resource Planning, SupplyChain Management, and Customer

Relationship Management

• Enterprise resource planning (ERP): a set of integrated programs that manage a company’s vital business operations for an entire multisite, global organization

Figure 5.11: Enterprise Resource Planning System


An Overview of Enterprise Resource Planning

• ERP systems evolved from materials requirement planning systems (MRP) developed in the 1970s

• 1980s - early 1990s: organizations recognized that their legacy transaction processing systems lacked integration– Result: higher costs and poorer customer service

• Realization of a need for a system to coordinate activities and share valuable information across all the business functions of the firm, i.e., an ERP system


Advantages of ERP

• Improved access to data for operational decision making

• Elimination of costly, inflexible legacy systems

• Improvement of work processes

• Upgrade of technology infrastructure


Disadvantages of ERP Systems

• Expense and time in implementation

• Difficulty implementing change

• Difficulty integrating with other systems

• Risks in using one vendor

• Risk of implementation failure


Production and Supply Chain Management

• ERP systems follow a systematic process for developing a production plan– Sales forecasting– Sales and operations plan– Demand management– Detailed scheduling– Materials requirement planning– Purchasing– Production


Customer Relationship Management and Sales Ordering

• Customer relationship management (CRM) system: a system that helps a company manage all aspects of customer encounters, including marketing and advertising, sales, customer service after the sale, and programs to retain loyal customers

• Goals of CRM– Understand and anticipate the needs of current and

potential customers to increase customer retention and loyalty

– Optimize the way products and services are sold


Customer Relationship Management and Sales Ordering (continued)

• Sales ordering: set of activities that must be performed to capture a customer sales order

• Essential steps include:– Recording the items to be purchased– Setting the sales price– Recording the order quantity– Determining the total cost of the order including

delivery costs– Confirming the customer’s available credit


Financial and Managerial Accounting

• General ledger: main accounting record of a business– Assets– Liabilities– Revenue– Expenses– Equity


Financial and Managerial Accounting (continued)

• In an ERP system, input to the general ledger occurs simultaneously with the input of a business transaction

• Financial accounting: capturing and recording all transactions that affect a company’s financial state and using these documented transactions to prepare financial statements to external decision makers, such as stockholders, suppliers, banks, and government agencies


Financial and Managerial Accounting (continued)

• Managerial accounting: use of historical and estimated data to provide information that management uses in conducting daily operations, in planning future operations, and in developing overall business strategies


Hosted Software Model for Enterprise Software

• Target market: small-to-medium businesses

• Offered by vendors such as NetSuite, Salesforce.Com Inc., Everest Software, and SAP

• Appealing to small businesses because they:– Can experiment with powerful software capabilities

without major financial investment– Do not need to employ a full-time IT person to

maintain key business applications– Can expect additional savings from reduced

hardware costs


International Issues Associated withEnterprise Systems

• Challenges that must be met by an enterprise system of a multinational company include:– Different languages and cultures– Disparities in information system infrastructure– Varying laws and customs rules– Multiple currencies


Summary

• In business-to-business (B2B) e-commerce, the participants are organizations

• In business-to-consumer (B2C) e-commerce, customers deal directly with the organization

• In consumer-to-consumer (C2C) e-commerce, participants are individuals, with one serving as the buyer and the other as the seller

• Mobile commerce (m-commerce) uses wireless devices to place orders and conduct business


Summary (continued)

• Transaction processing systems (TPSs): process the detailed data necessary to update records about the fundamental business operations

• Transaction processing cycle: data collection, data editing, data correction, data manipulation, data storage, and document production

• Order processing TPSs: order entry, sales configuration, shipment planning, shipment execution, inventory control, and accounts receivable


Summary (continued)

• Purchasing TPSs: inventory control, purchase order processing, receiving, and accounts payable

• Accounting TPSs: budget, accounts receivable, payroll, asset management, and general ledger

• Primary benefits of implementing ERP: improved access to data for operational decision making, elimination of inefficient or outdated systems, improvement of work processes, and technology standardization
