Jim Stewart (1952–)

I ordered this book from its title only, under a misapprehension. It isn't intended for individual learners but for personnel managers and others responsible for employee performance in commercial establishments. It could also be used in government offices. As the time when I had any responsibility of this kind has long gone, I don't feel qualified to judge how useful it could be or to give it a star rating; the only thing I can say is that any system would be better than none.
