Process Functional Modeling (PFM) is an analytical tool to learn the process through modeling of different operations, solving problems, and defining ways to the improvement of any fabrication process. PFM is an extension of the System Functional Modeling (SFM) and it allows us to analyze the whole process vs one particular operation in the process.
Among many cases when Process Functional Modeling is useful for us as problem solvers and innovators, we want to highlight just a few:
