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.
