Levels of e-Commerce Sophistication
Level Characteristics
Primitive Static web pages or ‘brochure ware’
Searchable site with dynamic pages such as an online catalogue
Integration with operational databases, e.g. inventory searching, package tracking, job postings
Customer transaction through the Internet, e.g. selling products and services, buying and selling shares, applying for loans
Advanced Full electronic commerce (i.e. integrated fulfillment cycle of ordering, shipping, billing)
The Reasons for Implementing e-Commerce
• A Customer’s standpoint:– Increase in demand for choice (product depth, global
reach, price choices)– Demand for information (detailed product information,
inventory, order status)– Demand for interactive, online support– Avoidance of travel and parking difficulties for
consumer e-commerce– Elimination of time constraints (that is, opening hours
or delays between placing an order and delivery)
The Reasons for Implementing e-Commerce
• A business customer’s standpoint:– Lower purchasing overhead – especially for small
value and repeat orders– Greater choice (greater product depth and global
reach)– Faster fulfillment cycle time (ordering, shipping,
billing)– Greater ability to supply information (inventory, order
status, etc)– Lower cost than EDI
Exp. Dell Computers
The Reasons for Implementing e-Commerce
• A supplier’s standpoint:– A global reach, leading to more orders– Reduced administration overhead– Integration between back office and online ‘shopping’
activities– Integration of online ‘shopping’ activities with
database marketing– Less need for distribution via channel
– Reduced working capital (inventory)
