Training is available to address most of the topics above, and exercises can be beneficial if they move us to another level of understanding. But don't overlook the simple solutions. Designing an off-site activity for the team, sometimes just to play together, is a powerful way of building camaraderie. In general, people and teams are stimulated by being given responsibility. Having ownership of an identifiable block of work is a long-held tenet of motivation in groups.
Responsibility can be tricky, however.
Implied in this concept is the understanding that the responsibility comes along with authority to make the necessary changes. Teams that have both the responsibility and authority tend to maintain motivation over longer periods of time. Responsibility can be demotivating if the consequences of error or failure are too great. If the organization, for example, has a history of punishing mistakes, then the giving of responsibility is viewed more as a negative. It is difficult to sustain high performance when energy is being sapped by fear.
