Working group is kind of social group that occurs in the workplace. It is therefore an intrinsically and functionally interconnected whole of at least two co-workers who are united at least by common workplace (place of work). Working group has usually its specific internal l values and standards. These can be either in accordance with the values and standards of the organization - which is fine, or contrary - which indicates value conflict.
Working team usually distinguishes from working group. Nicky Hayes defines a team: “A team differs from a working group in that it is fundamentally task-oriented and composed of people with different, but complementary knowledge and skills… What is often called a “team” is, typically, a group of people working together - amicably enough, but without co-ordination, common objectives and a sense of teamwork. Strictly speaking, it is a working group rather than a team and this is quite an important distinction.”
The main feature of the team is focus on a common working task.
Working teams can be divided into different types - see Working team typology.
In working groups and working teams are formed different roles.
