Disruptive Technologies

Successful, well-run, well established companies loose markets, when they fail to differentiate between sustaining and disruptive technologies.

Sustaining technologies improve established products. They are usually developed by companies holding a leadership position in their industries.

Disruptive technologies start with features that a few fringe customers value. Products are typically cheaper, simpler, smaller, better performing, and more convenient to use.
