For more than 26 years, Alexander Friedman has helped companies create and implement management systems. In his book “Time Eaters,” he offers advice on how to manage yourself and others effectively. His recommendations are based on the “Theory of Constraints” by Israeli economist Eliyahu Moshe Goldratt, which helps distinguish real performance indicators from illusory efficiency. Friedman also examines managerial “chrono-phages”—wrong approaches that consume time and hinder effective management.
