Him getting mad when people don't act according to his standards is likely cuz he is boss. I mean isn't that what bosses are supposed to do, set standards and then enforce certain order? That his standards are unrealistic might be because he is not a super intelligent guy. Alternatively, he has reasons for doing things that are not clear to you at this point, so you think that he is doing something stupid when in reality what he is doing actually works. Not checking whether his procedures are actually hitting the goal might have something to do with Te-DS I agree.
