Relational Matrices October 7, 2007

Posted by Coolguy in Six Sigma.

This tool can aid with the prioritisation of key process input variables.

  • Key process output variables are listed horizontally
  • Key process input variables are listed vertically.
  • For each output variable, assign a priority number
  • Within the matrix a number is entered for the effect that each input variable has on the output variable
  • Multiply the process output priority by effect value
  • Sum the results from above step

This shows which of the input variables have greatest effect on output variables.
