I think I know that asking the grid-interview question in the right context is
very important.
In other words, when asking someone to distinguish between people in a triad, it
is NOT
useful to just ask, "How are two of these the same and the third, different?" if
one is
wondering about eating habits or table manners.

I want to enquire into how each of 12 managers sees each other relating to team
cohesiveness. Do they see each other as adding to cohesiveness? Detracting from
it? Do they
see each other as engendering cohesiveness through behavior of some kind? What
is that? If
distracting from cohesiveness, what do they do that causes that?

This in mind, how might you formulate the interview question? Might it be
something like
this:

"Tell me how two of these (in the triad) are the same and different from the
third, with
respect to cohesiveness of the team." Is is that simple? Is it the most potent
formulation of
words? Is there a better way to phrase it?

Thank you!
