Notes on The Innovator’s Dilemma: When New Technologies Cause Great Firms to Fail

Notes on The Innovator’s Dilemma: When New Technologies Cause Great Firms to Fail

  • Book by: Clayton M. Christensen, Cambridge, Massachusetts: Harvard Business School Press, 1997
  • Prepared by: B.B. McBreen. See [PDF][1] (more readable but it's not plain text)

Summary

  1. Market progress is separate from technology progress. Customers do not always know what they need.
  2. Innovation requires resource allocation which is extraordinarily difficult for disruptive technologies.
  3. Disruptive technology needs a new market. Old customers are less relevant. Disruptive technology is a marketing problem, not a technological one.
