Management science is not so comprehensive or accurate as a physical science such as math or chemistry. Physical sciences deal with nonhuman entities, and it is the inclusion of the human element that raises questions in some minds about management qualifying as a pure science. Different people will not think, act, or react in the same manner under identical circumstances. Therefore, management will never become as pure a science as the physical sciences, but great strides have been made in systematizing knowledge and generalizing certain truths, which will be evident throughout this book. Management is indeed a social science, a term that accurately describes its true nature.
