Trade-off simply implies decision making.

What is Trade-off ?

In economics, the term trade-off is often expressed as an opportunity cost, which is the most preferred possible alternative

Trade-off like I said requires decision making whereas the idea of not planning a particular thing properly would rather bring up and down in a particular situation if not planned well.

This usually happens when your trying to make all your plans work perfectly especially when time and money is involved the idea of trade-off due come in.
