This book is aimed primarily at beginning and novice managers. Experienced managers looking to broaden their management skills may also find it useful. The book introduces more than twenty proven management concepts to aid managers in their job. The approach in this book differs from many other management books. Most books introduce a few core concepts and use case studies to justify their relevance and demonstrate their use. In contrast, this book explains the logical basis underlying each concept to give readers a deeper, common-sense understanding of their use in management. This approach allows more concepts to be covered than in comparable books. In addition, the logic-driven approach makes it easier for managers to adapt concepts to their unique problems.More than one hundred figures and diagrams are used to illustrate management concepts and their use. Liberal use of cartoons, illustrations, and graphics are utilized to make concepts understandable and memorable. Among the concepts discussed are tactical and strategic planning, time-resource optimization, multitasking, resource-cliffs, information turns, learning curves, disruptive technologies, use of metrics, reward-risk balance, management leverage, technology drivers, core competencies, business plans, model-based optimization, root-cause analysis, modularization, collective problem solving, one-on-one meetings, and managing change.This book represents the wisdom the author gained through more than 34 years in management.
