The batch control project is covered from process flow diagram to exception handling to its release to Operations. The project is divided into six sections. Each section begins with the knowledge required to do the section, followed by three things to be created and ending with a review of the work done. The review allows other people to either agree with you or question your mental capacity and parentage. Go no further until you can get through a review unchallenged.

What you will end up doing is teaching operators how to make a product. The operators know basic control, or can learn it from another class. If batch control is automated then you have to teach the machines, too. Machines take you literally and do not innovate work-arounds, so you have to be very careful and accurate, leaving nothing out. That last thing is the hardest part.

You don't really teach the operator how to make a product. The recipe does that. You have to teach operators how to read a recipe (and authors how to...
