A more interesting question is how do you detect if there is any?
Usually things flow in one direction, from diagrams down to the code.
This is why people attempt to promote diagrams to requirements. Because
otherwise you have comebacks, like:
1. Find all diagrams related to procedure Foo?
2. If specification of parameters Foo change, what changes on the
diagram A45-34E?
Now, as a purist, you must say, OK, if something felt wrong in Foo, I
ditch all the code, modify diagrams I suspect responsible for the mess
and then write the code all new...
