    We are doing cable harness manufacturing (batch productions). Our processes will be finished within a short time span. Eventhough we are doing number of products, the quantities are 50-100 per product. How to do SPC on our processes.

    Sowmya Hi
    You first have to do a capability study on your process. Identify what is to be measured on your cables, then run the process and pull some samples over a period of time i.e. a sample size of 5 is good for capability studies. Then take you average of each sample and the grand average of the whole process and with your statistical tables or software you can work out your upper and lower control limits. Hope this helps.
