What?
Why?
To work on critical business issues
To select a cross function team
To map the process
(as is & should be
To identify & define major product,
process and machine parameters
To quantify the measurement error
To assess process stability &
estimate process mean & variation
To compare process performance
to customer requirements
To identify cause & effect relationships
To implement preventive procedures
& steps to assure a stable & high
performance process
To implement best practices & standards
To leverage resources
To expand knowledge & creativity
To get a visual picture of the process
To use 80/20 principle
(80% of the performance will be
controlled by 20% of the parameters)
To verify the measurement variation
is less than 10% of the process
variation or spec.
To verify the process is stable
To estimate the process mean/variation
To compare the process performance
to spec.
To find important input variables
To assure proactive & preventive
thinking is implemented
To assure est process monitoring
