It is not the strategic and financial strengths of an organization that are decisive… but the strength and health of teams. That will be the ultimate competitive advantage in the future. Do you enjoy working in your team? Do the team members give each other feedback in an effective way? Does each member have the same interests? A successful team is a team that works together constructively and with pleasure, making optimal use of the unique qualities and strength of each team member. But sometimes this does not work (yet) and there is an undesirable situation in which cooperation is difficult. As a result the effectiveness and productivity will be too low.
