New models - relationships in the e-economy

Pottruck and Peace (2000) talk about four types of company based on their ability to manage complexity and relationships in the e-economy:

Dot.com start-up: Characterised by the simplicity of their business models. Excel at managing relationships but are often ineffective at managing supply chains.
Bricks and Mortar (BAM): Traditional companies that can earn good profits and have substantial revenues. They may suffer from fragmentation, inertia and an inability to engage in e-commerce. Their challenge is to retain talent and develop new competitive capabilities.
Dot.BAM: Growing out of BAMs, learning to combine the weight of a traditional multinational with enthusiastic championing of e-commerce to develop strong links to the e-world.
Dot.Clicks and Mortar: Rare organisations that learn to combine an effective web presence with an efficient, responsive supply chain. Often they do not own the key elements of the supply chain, but manage demand, supply and fulfilment better than most.
