Teamwork is the concept of people working together cooperatively as a team in order to accomplish the same goals/objectives.
A general dictionary defines teamwork as a "Cooperative or coordinated effort on the part of a group (sociology) of persons acting together as a team or in the interests of a common cause, unison for a higher cause, people working together for a selfless purpose, and so on."
Applied to workplaces teamwork is a method that aligns employee mindsets in a cooperative and usually selfless manner, towards a specific business purpose. Today there is no business or organization that does not talk about the need and value of teamwork in the workplace. While the concept of teamwork and its benefits are well known and talked about, it is very rare to see it being practiced truly in reality. And you may have often noticed what appears outwardly as teamwork is not really teamwork internally. Some things cannot be accomplished by people working individually. Larger, more ambitious goals usually require that people work together with other people. Because of this, teamwork is a desired goal of many businesses and organizations today. Projects often require that people work together in order to accomplish a common goal. Although critics often argue that in the corporate world teamwork has become an empty buzzword, or a form of corporate-speak. Effective collaborative skills (knowledge) are necessary to work well in a team environment. As businesses and organizations become larger or more sofisticated. Many employers attempt to enhance their employees' collaborative efforts through training, cross-training, and workshops in order to help people effectively work together in a cohesive group and accomplish shared goals.
