The book "Control Systems in Distribution Channels: a Field Study" offers a comprehensive analysis of control systems in distribution channels and their impact on the relationships between manufacturers and distributors. It examines how companies can combine the benefits of specialization with internal coordination mechanisms by collaborating with independent firms. The authors, Jose M. Sanchez, Maria L. Velez, and Concha Alvarez-Dardet, highlight the challenges that arise from the implementation of control systems and analyze the goals that companies pursue in this context. Through a structured field study consisting of two investigations, the role of control systems and their influence on trust between manufacturers and distributors are examined from various perspectives. This extensive study provides valuable insights into the dynamics of distribution relationships and the significance of control mechanisms in today's business world.
