The self-organized regulation of the internal distribution of tasks brings with it special challenges such as unclear goal and priority setting, diffuse task distribution, relationship conflicts or role ambiguities. Successful teamwork requires team competencies and the interaction of the team members with each other is in the foreground. The goal is joint learning, synergies and solutions. This also includes personal issues, which, however, are only dealt with to the extent that they particularly hinder or promote the joint process. The advantage of team development is that the newly acquired knowledge and the experience already gained in a protected setting can subsequently be put into practice together.
