All of them agreeing on one thing; teamwork is extremely important for the success of a company. How you describe teamwork is also important, and once it is defined, it can be achieved.
Teamwork has often been described as one plus one equals three. On teams, people can work together and accomplish much more than they could by themselves. This concept of synergy is how many sports teams achieve success. Often, the teams with the best players do not win championships. It is frequently the teams that work best together that accomplish great things. Your company can also accomplish great things when everyone is working together toward a common goal. Define that goal clearly and watch your people achieve it.
