Are Your Projects Failing Because of Group Dynamics?
“If you’re working in a big group, you’re fighting human nature.” So says Nathan Zook in a recent article for 37 Signals. (http://www.37signals.com/svn/posts/995-if-youre-working-in-a-big-group-
youre-fighting-human-nature). In fact, the research shows that the most effective and efficient project groups tend to be in the range of 8 to 14 people.
Referring to a report on business author Antony Jay’s book, “The Corporation Man,” Zook says that the ideal group size has historically hovered around what Jay calls a “ten-group.” Apple calls these groups “2-pizza teams,” meaning that the entire team can be fed with two pizzas – most of their best products have been the result of 2-pizza teams. Within a group that size, decisions are made quickly and collectively, effort is evenly distributed and actions are highly mobile and quickly maneuverable.
Let the group get larger than that, however, and it gets unwieldy. Decisions have to be formally discussed in a series of meetings, as members of a larger group are often out of the loop. Some members may slack off or have their voices drowned out by other more charismatic members. Eventually, larger groups devolve into cliques and other subgroups as the group dynamic tries to equalize itself around the ideal, slowing the work and stymieing progress.
Whether you’re leading a project team at work, organizing a church committee or starting a political action group, you should keep this dynamic in mind when choosing your team. But what is it, exactly, that makes a ten-group such an effective size? And how can you successfully staff your team for best effect?
