11.1 Work groups and group dynamics
Consider this
Refer to the following diagram. In the first box note the line marked X. Now refer to the second box: is A, B or C equal to X?

It is obvious that X is equal to B - right? It is. However, in experiments conducted in 1951 Ansh demonstrated some interesting group dynamics. A group of people were charged with the task of convincing an 'unsuspecting' subject that B and X were not equal. In 35 percent of the time the group was able to convince the unsuspecting subject to agree - not much you think - well it is if you consider how much 35 percent could add up to in organisational costs!
Now we will clarify some of the terms used throughout this chapter. The following reading provides a grounding. As you work through it, focus on the definitions at the side of the reading. The reading outlines the types of groups, how informal groups develop, member roles and work group processes.
