"When bargaining power of suppliers is high and rivalry among competitors is low, which eBusiness model reduces supplier dominance?"
When suppliers hold strong monopoly power, the business strategy is to reduce supplier strength through collective bargaining. The Revenue Sharing model achieves this by bringing multiple competing companies together through a shared digital portal.
"A company sells directly to consumers via its own website, bypassing all distributors and retailers. Which model is this, and what is a key advantage?"
DELL Computer is the classic textbook example. In the traditional model, manufacturers sold through distributors → dealers → customers. D2C eliminates all intermediaries so the manufacturer sells directly.
"A travel website aggregates airline tickets, hotel bookings and car rentals from third parties under one platform, earns commission and also sells its own products. Which model is this?"
The FSP model is a one-stop solution for customers. Rather than dealing with multiple vendors, the customer interacts with a single provider who handles everything from sales to after-sales support.
By making it inconvenient to switch providers, FSP directly counters high buyer bargaining power — customers who can compare prices easily are locked in by convenience and integrated value.
Porter's Force → Bargaining Power of Buyers"What is the primary strategic purpose of the Digital Value Hub (eRegion), which connects T1/T2 suppliers, manufacturers, distributors and customers?"
The Digital Value Hub is unique because its strength comes from the entire ecosystem, not a single company. It represents the concept of the Extended Enterprise — where an organisation's value chain extends beyond its own walls to include all supply chain partners.
The Boeing 7E7 (Dreamliner) case illustrates this — aircraft components were designed and manufactured collaboratively across Japan (Mitsubishi, Fuji, Kawasaki), Australia, Canada, Italy, and the USA, all digitally integrated.
Porter's Force → Threat of New Entrants · Bargaining Power of Suppliers"Chocos has a declining global share and strong local suppliers. Which combination of eBusiness models most holistically addresses its situation?"
Chocos faces multiple simultaneous Porter's forces, so a single model is insufficient. Each model in the combination targets a specific threat:
This multi-model approach aligns with the 7Es eTransformation methodology — from environmental analysis (Stage 1) through goal-setting, eReadiness, roadmap, methodology, eSystems, and change management (Stages 2–7).
