Business-To-Business E-commerce
Assignment 6 One of the major problems to be solved in B2C eCommerce is getting supplies to you and shipping products to your customers. Another issue involving distribution is ensuring that all non-electronic communication arrives on time at the right place. Investigate the types of support available to your company from the following three companies, The United States Postal Service (www.usps.com), United Parcel Service (www.ups.com) and FedEx (www.fedex.com). Write a two-page analysis comparing the business solutions available from the three organizations. Select the one organization you believe would best support the business activities of your company and explain the reasons for your choice. Two of the key factors in deciding which organization(s) would best serve your company is cost and availability Due March 31 @ 2:05 PM © 2007 Prentice-Hall, Inc
The focus of this chapter is on several learning objectives The meaning, benefits, and opportunities in B2B B2B building blocks and their relationship to supply chain management Key B2B models and their main functions EDI as a B2B tool Role of leadership in B2B as an ongoing concern © 2007 Prentice-Hall, Inc
What Is B2B? Business has always been about exchange Money as economic value eliminates barter Today money is exchanged by the invisible transfer of funds between businesses via computer business relationships The Unique contribution of B2B e-commerce is in the way these relationships are established and maintained. B2B is a network of independent organizations involved in a business area or an industry B2B focuses on the concept of exchange Efficiency is a factor © 2007 Prentice-Hall, Inc
Distribution Channel Metrics B2B e-commerce was estimated at $624 billion in 2004. Expected to reach $7 trillion in 2009 US B2B eCommerce in 2006 > $2.7 trillion ~ 25% of all B2B transactions 94% of all ecommerce transactions http://www.census.gov/eos/www/2006/2006reportfinal.pdf © 2007 Prentice-Hall, Inc
Factors Driving B2B Today’s customer has become more cost conscious and value conscious and demands quality products in a timely manner Maturation of information technology and networks makes it possible to design a supply chain to meet customer demand The global dimension, involving distance, costs, time, variety, and uncertainty, makes it almost mandatory that the long supply chains be managed efficiently around the clock © 2007 Prentice-Hall, Inc
What Is B2B E-commerce? Alternative ways of executing transactions between buyers and sellers that are business organizations; a network of independent organizations and long-term trading partners What is involved in B2B? Complex procurement, manufacturing, and planning collaboration Complex payment terms Round-the-clock performance E-business is not information technology, and information technology is distinctly separate from e-business © 2007 Prentice-Hall, Inc
Examples of B2B Messaging products for facilitating secure, reliable data movement between trading partners Work flow and process flow products for implementing conversational logic between partners Trading partner management products for helping identify where the data need to go and how they should get there Directories for assisting businesses in locating other businesses that provide a particular service or product © 2007 Prentice-Hall, Inc

B2B VS. B2C B2C B2B How connection is set up Consumer-to-system Business-to-business Types of relationship Placing orders Executing payments Fulfilling orders Browsing of merchant’s catalog Sending feedback Online procurement Tracking order status Managing promotions, returns, and catalog info © 2007 Prentice-Hall, Inc
B2B VS. B2C (Cont’d) B2C B2B Nature of control Unidirectional Unidirectional to peer-to-peer Level of needs-based segmentation Moderate to low Sharper than B2C Sales complexity Moderate Complex © 2007 Prentice-Hall, Inc
Advantages and Disadvantages of B2B Replacing a purchasing bureaucracy with online links means savings Improved efficiency in ordering material Fewer errors Just-in-time environment that minimizes inventory sitting in the warehouse Disadvantages Possible antitrust violations (non-competitive behavior) Barriers to entry for competitors © 2007 Prentice-Hall, Inc
Supply-Chain Management and B2B The supply chain represents all the events associated with the flow and transformation of goods from the raw material stage to the end-user customer (SCM) refers to overseeing materials, information, and finances as they move from supplier to manufacturer to wholesaler to retailer to consumer Ultimate goal is to reduce inventory costs Lower cost lead to greater value Main types of SCM systems Planning applications Execution applications © 2007 Prentice-Hall, Inc

Trust in SCM The core of collaborative relationships over time is trust Trust elements Competence - the ability of the parties in the chain to meet commitments Cognitive and affect-based trust that assures you the vendor means well and stands by his or her reputation Vulnerability - choosing a course of action even if such action has a probability of failure greater than 50 percent © 2007 Prentice-Hall, Inc
Disaster Planning What if the chain snaps? Disaster planning - taking specific steps to ensure the flow of products and services during a disaster Growing awareness of the need for disaster planning so that the chain can keep operating Work with the highest-risk customers and collaborate on a contingency plan to suit their needs in the event of a disaster Empower employees on supply-chain disruptions and how to communicate effectively to minimize unnecessary delays © 2007 Prentice-Hall, Inc
B2B Models Buyer-Oriented B2B, a buyer purchases thousands of products and uses the Internet to open a marketplace and a Web site for suppliers to do the bidding Supplier-Oriented B2B, a supplier invites individual consumers and business customers to order products via its electronic market store Electronic Auctions, auctions carried out on electronic Web sites such as eBay Forward Auction is an auction where a seller entertains bids from buyers; an auction used to liquidate merchandise Reverse Auction is an auction used to solicit bids from sellers and service providers; the lowest bidder wins Internet Exchange Auctions, an electronic auction involving many buyers and sellers who trade bids and offers until an agreement is reached to exchange product for payment. A third party often operates the exchange © 2007 Prentice-Hall, Inc

Information Flow Between Buyer and Seller with EDI © 2007 Prentice-Hall, Inc
EDI Advantages and Drawbacks Benefits Cost reduction and time savings Improved B2B problem resolution Accuracy with integrity Drawbacks EDI has yet to catch on as the perfect solution to information flow or for doing business. EDI is point to point. EDI requires expensive VAN networking to operate at peak efficiency. EDI is not easy to use, learn, or implement. © 2007 Prentice-Hall, Inc
Justifying EDI Conditions justifying EDI implementation Volume of data Frequency of document transmission and reception Content sensitivity Time sensitivity An alternative is Web-based EDI © 2007 Prentice-Hall, Inc
Management Implications The goal of B2B is to line up partners, work with the partners, and allow the partners to compete for lowest price The changes in B2B are so intense that technology has become a mere enabler, not a solution Compensation is a major issue and always will be a high priority IT employees should be involved in the decision process, especially in projects that affect their jobs © 2007 Prentice-Hall, Inc
Chapter Summary B2B involves complex procurement, manufacturing, planning collaboration, payment terms, and round-the-clock performance agreements B2B and B2C have distinctive characteristics Among the advantages of B2B are suppliers using the purchaser’s Web site to respond online to bids and sell excess inventory B2B is part of the supply-chain process © 2007 Prentice-Hall, Inc
Chapter Summary (Cont’d) Among the models in B2B e-commerce are: Buyer-oriented B2B Supplier-oriented B2B Electronic Auction Intermediary-oriented B2B B2B integration is about coordinating information among partners and their information system infrastructure Most B2B traffic is handled by EDI, which is computer-to- computer transfer of business information between two businesses that use a specific standard format © 2007 Prentice-Hall, Inc
