Most managers today work solely on intuition rather than best practices plus intuition. People keep reinventing what it means to be a manager, instead of learning from others' experience and improving on it. People these days are not less talented; they have access to more information and they are fast learners. The problem is that there aren't enough places to learn from, as organizations — large and small — are so mercurial and unstable. This book summarizes the author's experience from two major sources: a) growing with different companies through all the management ranks up to Vice President in a mega US corporation in the computer industry, and b) from working as a consultant to dozens of companies and hundreds of managers from different backgrounds and industries. New and experienced managers will benefit from principles, approaches, and checklists for current managerial challenges. The book covers a broad range of managerial challenges — from role definition to strategy to communication. Readership: Managers and leaders of small and medium companies and mid-level management of large companies; general public interested in managerial leadership.
