Efficiency between centralization and decentralization of Purchasing

Companies are constantly faced with the challenge of solving problems in order to achieve their objectives and increase their competitiveness. Purchasing generally accounts for between 50 and 70% of a company's expenses and the way it is managed is often a determining factor in the company's success or failure. This is because of their cost but also because they contribute to the company's product or service offering. Thus the choice of a centralized or decentralized purchasing organization can have a considerable impact on the results of the structure and its capacity to face the requirements of its environment.
