A good article about making sure all the players actions are resolved in a sensible order. By hearing what everyone plans to do before starting to resolve things you can avoid lots of potential problems.

I must admit that this isn’t something I tend to do, I tend to run games without a defined initiative system so just ask my players what they are doing and everyone gets a chance as we go around, this could potentially lead to situations where someone was planning a set up action but another player got there first but my group are pretty happy to say hang on a second it makes more sense for me to do the thing first then you go after so we’ve never really had a problem with it.

I can see it helping if you had a less familiar gaming group or players who were less happy speaking up when it’s not “their turn”.
