A working group is any number of people who work in the same setting and share - a common set of concerns. What distinguishes a mere working group from a “team” is accountability - working group members are individually accountable for specific goals, but there is no joint effort or mutual accountability. Their output is the sum of the individual contributions. Much worse is a Pseudo Team - a large group of people who call themselves a "team", while not functioning as such and whose interactions actually detract from each member's individual performance. Their output is less than the sum of the individual contributions. Examples often are notorious and include most committees, many “Quality” teams, dysfunctional families, prima-donna sports teams, and the figure skating “team” of Nancy Kerrigan and Tonya Harding.
