Formula compare – production efficiency

Sometimes the best way to improve the production is to look at the differences between what materials we planned to use ver. what we actually used. It supposes to be the same, but if you have more then 1 material that you can use as a substitute then probably your planned and actual cost per batch are not the same in some cases. That allows you to find places to do a major improvement. This post is not easy but very important.

Right first time: Using SPC to improve RFT

Starting production with the right parameters with low scrap and almost no time consumption is important for production efficiency.
RFT=right first time
RFT is a challenging task for most production organizations that produces many products/parts.
Using SPC is a good way to solve problems regarding RFT.
How can we find the parameter that we can improve, out of hundreds of products and dozens of parameters that each product has in its spec?
