The book "Systems Approach to Management: A Handbook for Corporate Decisions" explains in a practical manner, the rational approach to decision-making. It highlights the consequences of corporate decisions on the organisation as a whole. Hence, the need for decision makers at all levels to weigh the consequences of each decision from the system's perspective. This approach would checkmate the incidence of working at cross purposes and sub-optimisation. Corporations thrive as going-concerns on viable decisions in all areas of their operations such as: production, finance, procurement, lending, investment, human resource management and marketing. The essence of this handbook therefore is to serve as a guide to the knowledge of systems implications to sound decision-making in these areas and more to ensure negative entropy in the organisations. Overall, it would be a useful material to students, researchers, academics, consultants, practitioners and the reading publics in the realm of corporate decisions in particular and the field of management in general.
