This ebook makes evident the inadequateness of concepts and language based on industrial knowledge still used in current practices by managers to cope with problems of the post-industrial societies characterised by non-linear process of emergence and acquisition of properties. Its purpose is to allow management to use language and concepts more appropriated to deal with complexity, i.e., to represent, induce and orient processes of chance and second, to outline a theory of practice guiding their efforts, and to underline the urgency of a new general management education. Suitable, appropriated and open linguistic representations allow effective management of complex social systems where processes of emergence, i.e., acquisition of properties occur. Current educational process for managers should be rethought. The ebook can be used as a guide in helping practitioners in recognizing, inducing and managing complexity of processes and change.
