Most of these relationships seem to work well although the ISTjs seemed to do the lion's share of the grunt work while the ENTjs determine direction and goals. However, relationships will only work when there's a distinct division of roles and power. The ENTjs would have to let the ISTjs do it their own ways (no micromanagement) while the ISTjs have to understand, accept and deliver what the ENTjs want. ENTjs seem somewhat impressed by people who can do practical things for them and ISTjs usually have that in spades.
