I do the same when commissioning our products - winch systems for the offshore industry. My assumption is that the big, bad piece of machinery is actively trying to kill me and anyone in the vicinity if we give it even half a chance. Calling out the checklist items lead both me and others to not take any shortcuts and never assume anything, also ensuring everyone is up to speed on what is about to happen. I knew I was doing something right when, after intentionally leaving out a step to see if the apprentice was paying attention, I immediately got a good dressing down for my trouble.
