The only way to know for sure is by experiments/simulations. The heart of any competent operations team, whether its in computer systems or plain old logistics, is drills. You can't simulate every possible scenario, but you try to analyze and get an initial set, and the build that up as you run into actual production issues. What you want to avoid is running scripts for the first time in the middle of a disaster.
