You cannot "manage" what you do not understand, MBA programs to the contrary (which is why I like working here). IOW, if you are going to lead a disaster relief agency, I think you ought to know first aid, cpr, logistics, and some basic civil engineering. Otherwise, one must ask, what exactly is this "manager" for?
As the director of a relief agency, you ought to know what ice is for and why it is critical that it arrive. Ditto food, medicine, fuel. Plus, they had a practice just for this one year earlier, learned a number of things, and DID NOTHING to fix them.
You blame the local authorities (with good reason), but by this time they had made themselves subservient to FEMA - who was supposed to be the central coordinator. Plus, that's outside my area of concern. Lots of people screwed up. So? Doesn't mean FEMA didn't.
