What is the group synergy? (*)
The so-called "group synergy" is probably the main justification for teamwork. We should note that the decisions made by a team require an investment of time far superior to individual decisions, using the mechanism of "trial and error". On the other hand, the time is a scarce resource in any organization, so there must be a good reason to invest time in the dynamics of a team. Well, the "group synergy" is the answer; it is the result that can be obtained from the interaction of a set of individuals towards a common goal.
When people work cooperatively, putting his experience, knowledge and willingness in order to solve problems of some complexity, the result that often get is much greater than the sum of individual results if the same people work on the subject in isolation.
We could exemplify, mathematically, by the following equation: 1 + 1 + 1 + 1 + 1 = 7, i.e., an additional value added, appears as a result of the interaction mentioned and only can be achieved by this way. The technical explanation is that the different ideas, when combined, generate others of higher quality that would never would have arisen without such combination.
Actually, this is only the first advantage of the synergistic effect, although perhaps the most important, the second is the acceptance of those ideas by all team members. This second advantage is strongly associated with the implementation of what was decided. Many very good or even brilliant ideas have been irrelevant in different types of companies and institutions, due to lack of adherence to the same of those who should implement them. When someone has not participated in the discussion of a major change that will affect him, will probably reject it, even when the change is beneficial for him.
In short, the "group synergy" justifies teamwork by providing to the organization two skills of high value: the first is the ability to improve decision-making to solve problems of some complexity through the generation of very creative ideas, the second is the feasibility of bringing these ideas into practice, by aligning the conviction and willingness of members of the team that participated in the generation of these ideas.
