Complex Decision Example
Suppose you have a decision with a large number of decision tables such as this:
After analysis by the validation engine we can see the following:
The five decision tables shown in orange and red don't use any of the blue decision inputs (or any values derived from those inputs). Its not necessarily an error; they might be checking system variables such as the date rather than input variables. If that's the case it may be better to show it explicitly as an input. In any case they should be reviewed.
Furthermore DT11 and DT10 do not affect the green output result at all and are either not needed or contain errors.
If this were modeled using DMN, the diagram might look like this:
