I have a question regarding Stabilty Factor as a metric in terms of Production performance.
Here is my application.
Currently we are collecting Cycle Time for different products
These 50-70 orders per day will have different CT because of different process and parameters/raw mats.
Now if i get the daily CT of product and run descriptive stat get Q1/Q3
Now my issue is this making sense? I was told that the main intent that we need to get the SF is to measure the stabilty of our process, we will use this as a metric.
Now I am not convince since we have a high product mix, Cycle time changes everyday. For me we can not really detect stability in this way becuase in the first place product is non -repeatable. For me that SF value will confuse me. Any improvements I made from process will not be showing stability because my CT changes due to product mix. Out of these 50-70 daily repeated products can happen only after one month. 3000+++ product mix..
Need input from you guys..Thanks
