Classification of Activity Parameter / Action Pin

[parkaneric]

For FMEAs Parameter Diagrams are in common use. As the diagrams aim to analyse the dependencies between system functions the diagram provide means to classify the input and output parameters of the function:

• input (general)
• control parameter (input)
• noise parameter (input)
• output (intended)
• output (unintended)

As this classification addresses a best practice for a functional analysis, is it worth thinking to introduce such a concept in SAF as well?
