It's not natural. We have been taught to be competitive in Western Society. We win at that expense of others. Great leaders access and take advantage of the skills, strengths and talents of the people around them. It is the process of collaboration that creates leadership within an organization.
Collaboration allows participants to contribute, create and implement new strategies and solutions.
Because they were part of collaboration, they have an interest in the success of the project. The more they contribute and the more they learn, the more skills and creative thinking they develop. It is growth like this that creates tomorrow's leaders. Collaboration isn't just a great experience for the participants. It makes sense.
