Today, cooperation is becoming a necessary condition for the success of any kind of activity. For a company to become successful, all its employees must feel responsible for the result, be aware of their involvement in the success of the product. This awareness is much more effectively achieved through a teamwork. I reviewed the basic principles and methods of team building, the criteria for the quality of a company’s goods or services, as well as the basic principles of quality management: customer focus, leadership, employee involvement, process approach, continuous improvement, evidence-based decision-making, relationship management. Quality improvement begins with the individual level, improving intra-team relationships through personality. Team building is able to ensure the maximum realization of the labor potential of each employee in a particular area. Therefore, it can rightfully be considered a serious investment in the success of a company operating in modern conditions and aimed at high-quality, highly productive work.
