This textbook brings together the previously separate fields of business management: procurement, production, and marketing, making it unique in the German market. Its added value lies in the clear presentation of the interdependencies and influences these economic areas have on each other. Scientifically rigorous yet comprehensible and concise, the structure of the work follows a distinctly application-oriented approach. Practical relevance is paramount here, as the authors' concrete experiences from industry and business are linked with the theoretical aspects of procurement, production, and marketing, allowing for a succinct and understandable presentation of the content. This textbook is particularly interesting for students and newcomers to the field.
