Kenneth H. Blanchard e Paul Hersey
In the preface to our first edition we made the following statements that we still believe:
For a long time management theory has been characterized by a search for universals-a preoccupation with discovering essential elements of all organizations. The discovering of common elements is necessary, but they do not really provide practitioners with “principles” that can be applied with universal success. In the past decade there has appeared a relative maturity in this field as it begins to focus on “patterned variations”-situational differences. We assume that there are common elements in all organizations, but we also assume differences among them and in particular the managing of their human resources. As the inventory of empirical studies expands, making comparisons and contrasts possible, management theory will continue to emerge. Common elements will be isolated and important variables brought to light.
