Abstract
In this paper we started from the idea that the most important strategic resource of an organization is people. Without people, the organization's other resources could not be operational, and the organization could not fulfill its established goals. Therefore, in order for an organization to grow and become competitive in the long run, it must invest in training the employees. It is true that this investment has high costs, but well-trained, creative, adaptable, motivated and involved employees in achieving the organization's goals generate positive changes in all its structures. Taken into consideration all the analyzed theories, we tried to demonstrate that an organization will become stronger, more adaptable to changes in both its internal and external environment and will meet its established goals becoming a successful organization
