I'm not really sure where this should go, I'm sure it'll find a home sooner or later. Anyway, I've got an Engineering Management exam tomorrow, and my revision has revealed some holes in my knowledge. Amongst other things, there are a few TLA's for which I'm struggling to find definitions. The lecturer is a big fan of using acronyms without defining them (he uses DBP's a lot in the examples in his notes, I've just found out that they're disc brake pads!) ERP? I have no idea about this, though the context is planning (perhaps this is the 'P'?) RPN? I know that RPNs are the scores given by an FMEA, but what does it stand for? ECO? No idea, but I know they're reduced by the use of a HOQ. EMV? Again, the context is planning. SMED? No idea. QFD? Is this another way of saying HOQ?! SPC? Should be pertaining to the Japanese paradigm? NPD? I know it's a lead time, but what does it stand for? DTI? In the context of government financing, would this be the Department of Trade and Industry? USP? Unique Selling Point perhaps? Context is marketing. I've already managed to work out what AON, AOA, JIT, FMAE, ESD, EFD, LSD, LFD, HOQ, TQM, ROS and ROCE are, but the remaining others are bugging me a bit.
