This document discusses the key components of e-commerce business models. It identifies eight elements that make up a successful business model: value proposition, revenue model, market opportunity, competitive environment, competitive advantage, market strategy, organizational development, and management team. Each element is described in detail. For example, the value proposition defines what a company offers customers that competitors do not, while the market strategy is the plan for attracting new customers. Strong business models include all eight elements and can adapt over time as needed.
