Re:Black Box....yes, but....... (Score 1)

This the same old reply that is always given to the specification argument. Thats why black boxes are a good thing, you build them to handle a very specific set of conditions that ARE fully specified and nothing else. IF the spec is complete and followed then no unexpected side effects result. IF the spec is BS, incomplete or not followed then boundary conditions will cause things to break or respond in unpredictable ways.
