Tribute is due to Edward Lorenz whose death marks the end of Chaos theory 1.0. He started the Butterfly Effect story that has become a folklore now.
Small variation in the initial conditions can create entirely different results in any system if same process is followed. This is the essence of Lorenz curves on weather forecasting.
This is really so simple, yet our Six Sigma friends, especially those who are trying to make Software development six sigma compliant really cant understand.
It will be interesting to see how much predictability can be there in software development processes. I have a lurking intuition it is dynamical and chaotic .
Bye bye Lorenz! May God Bless your Soul!
