How many questions should you ask?
It turns out that it takes an average of 110 questions to describe an operator workstation in a knowledge file.
We also know from experience that an average of 20 parameters and 72 instructions are needed to describe the core, including process monitoring and control (see figure).
As more instructions are described, a picture emerges of the number of ways the operator can control the process. This can vary widely: fully automated plants sometimes have only a few, but on average there are 5 to 12.
