Computers were made to help us crunch numbers — and they’re extremely good at it. Analyzing a process in detail is an exercise in number-crunching, so from the beginning, Six Sigma analysis has been a computer-intensive discipline. As a rule, practitioners resolve all the equations and expressions described in Part III with the help of computers and computers’ younger brother, the calculator. You can crank out some simple expressions and graphs by hand, but even the most elementary graphical analyses quickly exceed manual abilities as the data volumes and expressions multiply.
With the right analytical software, you can deftly create accurate and detailed plots; calculate cause and effect; analyze failure modes; determine degrees of normality; calculate throughput yields, defect rates, Z-scores, and process capabilities; conduct multi-factorial experiments; perform linear regressions; and implement blindingly accurate statistical ...
