Consider two alkenes,

puu.sh

This is very reminiscent of the $R$ $R$ and $S$ $S$ configuration assignments. We find an double bond that has a few different substituents, such as those above.

In the former molecule, it's $Z$ $Z$ since the highest priority substituents are on the same side of double bond.

In the latter molecules, it's $E$ $E$ since the highest priority substituents are on different sides of the double bond.

It's very straightforward compared when you first learned absolute configuration!
