Very little in the way of practical information. As someone who works in a fairly large organization that is moving towards a matrix structure, I do not feel any more prepared for this transition than I did prior to reading the book. There is not much meat here, the author could have presented the info in a medium-length article or (better) more fully developed the ideas through comprehensive case studies. The short quotes used to illustrate typically restated the author's points and felt scripted. Read the first and last chapter, skip the rest.
