How do we know which of these two methods to use? Are there specific conditions we should look for or will the question tell us which of the two to use?

My friend and I researched this and found:
The steady state method can only be used if the first step of a reaction is much slower than the second step, whereas the pre-equilibrium approximation requires the first step to be faster.

I don't know if this is completely correct but this is what we found.
