The purpose of this paper is to define and analyze the groups and teams within organization as most adequate framework that enable the collective learning. In addition the organizational learning process is presented, whose role is to identify possible changes at the organization level to become learning organization. The need to understand how the organizations learn and how they accelerate their learning process is greater today than ever. It is said that in the future, the only competitive advantage of a company will remain the ability to learn faster than its competitors. In a world where the only constant is change, organizations must adapt rapidly, renew continuously, and constantly reinvent themselves. Complex problems faced are effects of several causes. People need to learn to solve these problems on their own, to be aware that many answers depend on their ability to learn, to develop unique and particular capacities. Both groups, as traditional structures, as well as teams, as modern structures for organizing the work, are most appropriate frameworks which favors cooperation and exchange of information and knowledge between employees with major consequences on organizational overall performance. We are moving towards an era of human freedom, responsibility and intelligence, moving from a pyramidal management to a dynamic, shared management, of teamwork, of horizontal organizations.
