Re: Where is the Evidence?

["Jon Juneau" <jjuneau@pier.st.usm.edu>]

In a message dated 5/7/99, Frank Voehl asked for the evidence that 
"90% or more of variation is caused by the system."  I have also 
wondered about the same thing and when I read his message, I had a 
thought that IMHO is a good hypothesis for the answer.  This insight 
lead to two questions that I would like the DEN's help in answering.

My thoughts:
An assumption in the question is that some amount of variation can be 
attributed to components outside of the system (the less than 10% of 
variation that is not due to the system).  If X represents the 
contribution to the variation by the system, the question can be 
rephrased as:  what is the evidence that X is 90% or greater.  Now, 
letting Y represent the contribution to variation due to components 
outside of the system, the total variation can be (simplistically) 
represented as X + Y.

My Questions:
1.	Using the System of Profound Knowledge, by what method can 
evidence be collected to determine the value of X?
2.	If I accept, as an axiom, that X=1 (everything is in the system), 
will the statement that "X is 90% or more" be more acceptable to 
people that do not have the same axiom?

Thank you for your help in learning,
