Higher variability in output due to multiple variables unable to trace the variability.
Batch to batch variation sometimes is around 10%. 1% cost is in crores.
Just want to know if anyone interested in yield improvement projectSeptember 28, 2018 at 7:55 am #203067
So, what are the variables you think matter and what have you done with respect to examining production data to at least justify your variable choice? If you have a list – put together a screening design – run the design and use the Box-Meyer’s method to analyze the results to identify the big hitters with respect to variation.
Oh yes – what does “crores” mean?October 2, 2018 at 7:23 am #203079
Don’t forget to do some graphical and statistical analysis but have you done a process map and had X’s investigated.
What about the gage being a source of variability?October 2, 2018 at 11:59 pm #203088
I hope you have completed Project Charter and identified the Big Y which your project should address.
You can provide me the project details and I can support.
