One of the big tricks here is not to be religious about any technique. Pick what fits best given the information that you've got for the situation that you find yourself in and don't be afraid to change the mix over time as the situation changes or you find yourself in the possession of new knowledge that is inconsistent with your past views on the state of affairs.
If you blindly adhere to some method or other then you're going to find out exactly what the limitations are so you are going to have to be flexible and you're going to have to mix-and-match as time goes by.
As an example, 'agile' comes up here with some regularity. It's a great principle but it's not a religious thing. Feel free to adopt some but not all of agile to come out ahead. Adopt all of agile in a religious fashion and you'll come out a loser.
