Dual management system
The system of dual management in trading companies divides the profit responsibility (better: responsibility for the contribution margin of product groups) of purchasing and sales to the marketing and operating functions .
While marketing concentrates on sales through the presentation of goods and personal sales , the focus of the operating department is on the shelves ( quick response ) and thus in particular on logistics .
As a result of the discussion on the cooperation concept of category management between industry and trade that has been taking place since the beginning of the 1990s , the discussion on the dissolution of the supposedly prevailing separation between purchasing and sales has come back to the fore in the "corporate management in trade" debate.
