RE: Re: SIP is "just another Six Sigma measure"?

As I understand it, the manufacturing jargon for what SIP measures is
"production lead time". Cycle time is the pace at which finished goods
leave the line. This won't make a big difference unless we're talking to
real manufacturing people.

I would say minimizing cycle time is the same as minimizing SIP.  
Defining SIP is equivalent to defining the beginning and end of the 
cycle we are trying to minimize.  Focusing on minimizing cycle time 
has been very effective in six sigma programs - AS LONG AS it is 
accompanied by sensible focus on customer value, quality, and worker-
centric organization.
