Rapid changes quickly make yesterday's strategy obsolete. The future requires managers with the skills to integrate many unexpected and seemingly diverse events into planning.

Drake tried to enlist to his project to drill for oil in 1859 " This 'telephone' has too many shortcomings to be seriously considered as a means of communication.
