Any organization's business model is best understood, built, and refined through a systems approach that treats the organization as a whole and examines the causal relationships between critical elements of its success. The goal of any organization is to create a "circle of prosperity," that is, a spinning spiral of growth, income, profit. Unfortunately, this is often hampered by such "vicious circles" as lack of resources, overload, and quality problems. The method of building system diagrams proposed by the author allows you to connect growth factors with braking factors and build a visual business model that will show the manager which parameters should be influenced in the first place in order to significantly increase competitiveness. The book will be useful primarily to managers-practitioners of commercial organizations.
