A team is not automatically effective just because a group of competent and talented people is called to work together.
Groups must go through essential evolution that will start by a grouping of individuals – to arrive at a fully developed and successful team.
When people come together to create a team, it starts with a group of people, each with their own vision, their own ideas, and their own agenda. Then, they start to develop common goals and, by uniting their efforts to reach success, they become a group. It is only once they are entirely united and integrated and they feel all responsible for the results that they can call themselves a “team”.
