E-Supply Chains, Collaborative Commerce, and Corporate Portals
Upon completion of this chapter, you will be able to:
1. Define the e-supply chain and describe its characteristics and components.
2. List supply chain problems and their causes.
3. List solutions provided by e-commerce (EC) for supply chain problems.
4. Describe RFID supply chain applications.
5. Define c-commerce and list the major types.
6. Describe collaborative planning and collaboration, planning, forecasting, and replenishing (CPFR) and list the benefits of each.
7. Discuss integration along the supply chain.
8. Understand corporate portals and their types and roles.

These include replenishment, e-procurement, monitoring, inventory management, collaborative planning, collaborative design, e-logistics, and the use of B2B exchanges/supply webs.
4. List the major e-supply chain management infrastructures and enabling tools.
These include extranets, intranets, corporate portals, workflow systems, and groupware.
5. Describe a digital supply chain.
A supply chain that is managed electronically, usually with Web technologies.
6. Describe visibility and tracking along the supply chain.
Visibility and tracking are important so that there will not be any surprises related to order quantity or delivery times. Various systems and databases track production and distribution so that any needed adjustments can be made.
Section 6.2 Review Questions
1. Describe some typical problems along the supply chain.
Some problems include missed deliveries/improper inventories and quality problems.
2. Describe the reasons for supply chain-related problems.
There are several potential reasons, but many center on lack of communication and trust.
3. Describe the bullwhip effect.
The bullwhip effect is when large fluctuations in inventories along the supply chain occur, resulting from small fluctuations in demand for finished products.
4. Describe the benefits of information sharing along the supply chain.
The major benefit is an improvement in the overall functioning of the supply chain – better communication provides more information for better planning.
5. List some EC solutions to supply chain problems.
These solutions come in the areas of order taking, order fulfillment, payment, inventory planning and collaborative commerce.
Section 6.3 Review Questions
1. Describe how RFID can be used to improve supply chains.
RFID tags can be attached to products to more carefully monitor their location for inventory purposes.
2. Explain how RFID works in a supplier-retailer system.
Suppliers attach RFID tags so retailers can track shipment and receiving.
3. Briefly explain the differences between active and passive RFID tags.
Active tags include an internal power supply while passive tags do not.
4. In what circumstances would it be better to use passive RFID tags? And in what circumstances might it be better to use active RFID tags?
Passive tags are better in cost-sensitive, high volume settings where scanning is easy. Active tags are better in difficult to scan locations.
5. What are some of the major limitations of RFID technology?
• Cost of implementation
• Limited use by environment
• Lack of standards
6. Describe RuBee and its capabilities.
RuBee is a bidirectional, on-demand, peer-to-peer radiating transceiver protocol. RuBee has several complimentary features that include:
• Use of magnetic waves
• Longer battery life
• Better locatiblity
• Lower cost infrastructure
