Teamwork is the collaborative effort of a group to achieve a common goal or to complete a task in the most effective and efficient way. This concept is seen within the greater framework of a team, which is a group of interdependent individuals who work together towards a common goal. Teamwork brings people together (the bonding agent) and motivates them to rely on one another to get things done. Teamwork also makes progress easier (the lubrication) and allows the group to overcome obstacles that would have stymied an individual. Without teamwork, none of that would be possible.
