Humans are fundamentally social creatures: we love to get together. We are educated in groups, we work in groups and many of us worship in groups. But what, exactly, is a group? A group of people working in the same room, or on a common project, does not necessarily make a group.
When people work in groups, there are two different factors involved. The first is the task to accomplish, teaching a class, holding a ritual, or doing community outreach are examples of tasks. The second factor is process of the group work itself, the mechanisms by which the group acts as a unit. If group members don’t pay enough attention to the process, the value of the group can be diminished or even destroyed. The synergy between task and process makes group work attractive despite the possible problems (and time spent).
