Response from the Working Group
In the instructions, just above the list of sufficient techniques, it says
that you must do one of the numbered items. You do not need to do all three
(or more). Therefore, techniques often will contradict each other. They are
different options or different ways of doing something. You may choose among
them. You do not have to do all of them. In fact you don't have to do any of
them actually. These are just suggestions, ways of meeting it that the
working group has declared to be sufficient. You may come up with a
different method altogether, and, if it meets the success criterion, it
meets the success criterion. Someday you may be called on to prove it by
someone. Therefore it is convenient to use ones where you have evidence that
the working group said that it would be sufficient. But it is not required.
No techniques are required.
