I look at the question How do disruptive business models alter a value chain? Its the unique combination of strategic resources and key competencies that makes a firm successful. This combination must be non-imitable, rare, and create value that the firm can capture. What usually happens is that when a game-changing business model usually through a new technology and innovation is introduced is that this new business model becomes the average offer of reference in the market that it has disrupted, and market dynamics start to shift according to the new trends and business norms. Hence, termed as a disruptive business model. How do you see disruptive business models?
