six sigma sederhana (six sigma in a nutshell)

August 12, 2010

For any visitor would like to learn/refresh the  data-based problem solving or six sigma, I attached a file here.

This is in Bahasa Indonesia; I wrote it more than 5 years back. Apologize for strange style ( I was teeneger then :)) and  for not updating it.

Anyway, the basic is still relevant.
