Dear All, 


I believe there is a need for each technique to contain one or more simple
statements which define the conditions under which the technique is deemed
applicable - an example of such a statement might be simply 'This technique
is applicable if one or more data-tables have been used'.


The benefit of doing this is that it allows a user to determine without
doubt whether or not a technique is relevant to their situation - if it is
applicable they can proceed to test whether it is 'passed' or 'failed', and
if it isn't they can mark it as 'non-applicable'. 


By providing 'applicability conditions' I believe it further strengthens the
'testability' of the guidelines.  This extra step ensures that decisions as
to 'applicability' can be made with certainty, providing an almost
prescriptive framework (taking into account 'testable statements') by which
a technique can being declared as 'passed', 'failed' or 'non-applicable'.  


Please let me know your thoughts.
