There is very little "team" in teamwork without a lot of motivation. We live in a society that seems fascinated with individual accomplishment and almost oblivious to teams. Even in team settings like sports, we single out the All-Stars and the MVP (Most Valuable Player) of each game. That is the environment you have to overcome in order to build your group at work into a team.
Get Started Team Building
Do you think of your group as a team? They won't think of themselves as a team if you don't. Do you reward team performance, or only individual achievements? You won't have much success in team building if you don't reward team performance. Let your group know that they are a team, that you expect them to perform as a team, and that you will reward their successes as a team. That's the first step toward team building.
Remember that team building must be an everyday activity. It is not something you can just do quarterly at some off-site function.
Motivate Team Building
If you want team building to work, it's not enough to tell them that they are a team and must perform as one. You also have to show the members of the team that it benefits them personally.
Most of us are selfish individualists. We watch out, first and foremost, for ourselves and do what benefits us most. We have to be motivated to include anyone else. Fortunately, it is pretty easy for us to see the benefits of including others, so most of us do that readily. Love is a strong motivator. Parents, for instance, watch out for their children. Money is another strong motivator. It is one you can use as an employer. However, the strongest motivator available to a manager (since it is unlikely your employees will fall in love with you) is self esteem. The more the individual sees a benefit to his or her self esteem from supporting the team, the more successful your team building efforts will be.
First of all, your people have to acknowledge that they are part of a team. You can reinforce this by holding team meetings, posting team news on the bulletin board or your intranet page, and tracking team performance against team goals.
Secondly, they have to believe that the team is capable of producing more than the sum of its members. Lance Armstrong is a great bicycle racer, but he could not have won the Tour de France without the support and assistance of his team members. You may have a great customer service rep on your team, but without the cooperation of the other members of the team he or she would not be able to handle as many calls. You have to make this readily apparent to them and clearly delineate the increased rewards they can achieve through teamwork.
