Centralisation refers to the concentration of power or authority within a single entity. In business, centralization often occurs when management makes decisions without consulting other employees. This can lead to a lack of transparency and communication within the organization, which can ultimately have negative effects on morale and productivity. Centralization can also have positive impacts, however, such as streamlining decision-making processes and increasing efficiency. Ultimately, the level of centralization that is right for a given organization will depend on its specific needs and goals.
