Traditional management training prioritizes clarity, predictability and control. In a matrix we need to be able to balance this with the ability to tolerate ambiguity, manage uncertainty and decentralize control. Managers need an expanded toolkit to help them move from the hard to the soft, from the concrete to the ambiguous and back again depending on the situation. Making the Matrix Work helps you develop your matrix mindset and will show you how to establish and engage networks that do not depend on role, control or authority to get things done.

Moreover, why does hadronic matter only account for four percent of the stuff that makes up the universe? This audiobook takes a look at what nothingness is and asks the question - where did everything come from in the first place?
