What is the difference between a team and a work group?

What will be an ideal response?

A team is a small number of people with complementary skills who are committed to a common purpose, a set of performance goals, and an approach for which they hold themselves mutually accountable. Team members interact with each other on a regular basis. A work group differs from a team. Members of a work group are held accountable for individual work, but they are not responsible for the output of the entire group. A team shares leadership roles while a group is likely to have a strong, focused leader. Group membership is more variable over time while team membership is bounded and stable over time. Teams openly discuss goals and procedures with each other until they reach a consensus.
