While C-Suite Members are adept at drawing Matrices with two, three or four at times more dimensions - I have personally found Dualism very useful in different situations. For e.g. I have used:
Manner v/s Matter. Style v/s Substance.Tone v/s Tenor many times in complex situations at work and found answers.
The good thing about this is Binary logic and no room for Fuzzy Logic or ' In between or creation of shades - like an argument in which we say " Either we Trust, or We Don't - there are no in betweens - there is no percentile while Trusting someone or otherwise'.
