The relationship between decisions and trade offs is that decision is directly connected to trade offs because what an individual prefers can have a consequence on result. Trade-offs should be analyzed carefully to be sure no risks are involved. Every single decision made has a trade-off, because you have to give up something to get some other decision.
I believe the answer is:  decision is directly connected to trade offs because what an individual prefers can have a consequence on result. 

in a decision, the choice that we made is a result of hard analysis between two equally important options. 
In trade off on the other hand, we make a certain compromise that we pull out from two desirable option but they are incompatible with one another.
