I have used this book during my undergraduate and postgraduate business + management degree.
It is of such depth and clarity that I almost needed no other sources for most of my essays + exams. The recommended readings are all essential, the theories mentioned more up to date than most other textbooks in the field (and I have looked at quite a few during my courses) and the structure + examples are very relevant.
It is definitely better than Beardwell's or Marchington's textbooks, and only matched by Bratton + Gold's textbook (which has a stronger practical focus I find but does manage to put theories into a broader context sometimes).
This is one of the best textbooks I have used during my academic career.
