Lean Startup, a new process ?

Hummm .... it seems that there's new way to build startups:
http://en.wikipedia.org/wiki/Lean_Startup

It is based on a learning style called validated learning:
The process steps are (from Wikipedia) :

1. Specify my goal
2. Specify a metric that represents this goal
3. Act to achieve it
4. Analyze the metric - did you get closer to the goal?
5. Improve and try again

It seems to me that is the Plan-Do-Check-Adjust management method, isn't it ?
