Dear All
I have a question related to application of statistics in Six Sigma Project. Do we really need to use statistical analysis? For example, I have done a project to improve the test station capacity.
There are many ways to improve the test station capacity which can be done by improving the test algorithm, reducing equipment communication access time, UUT access time, waiting time and etc. By doing all this optimization , I have managed to reduce the test time from 80 mins to 60 mins. So this helps to improve the test station capacity.
In this case, what type of statistically tool can we use or it is really necessary to use the statistic to justify the time improvement. Based on test time, there is obsolete improvement. Please advice. thank you
