What was good in the past, is sufficient for the future is not nearly out more. Gary Hamel predicts the end of the retracted optimization mentality (read: the future = past + a little optimization) and propagated an era in which companies have already come up with revolutionary innovations, so as not to survive itself. Hamel formulated clear theses and brings the arguments conclusive on the point. No doubt that the sedate corporate giants will come sooner or later stumble, if they do not turn into "greyhaired Revolutionaries". My absolute favorite business book because forward-looking and true. Be sure to read the original. German translation and presentation of the book are only a pale reflection of the lively, English-language original.
