Web Marketing Team or Workgroup

Is your web marketing team functioning like a team or a workgroup?

When I was in business school we studied both workgroups and teams. The differences in the quality of output could be dramatic.

Here is a short refresher;
Workgroups have a strong individual focus. They typically exist with minimal supervision and do more coordination with each other than collective works. An example would be that within a group of product marketing professionals each member is assigned separate products to bring to market and each team member works and is concerned only about his particular products or tasks.

Teams typically produce collective works comprised of contributions from team members. Accountability is shared and products are the result of group efforts not just individual parts. Teams share a common purpose and set of performance goals. Team members are mutually accountable.

My experience working in both product marketing and centralized web marketing organizations is that workgroups are much more common than true teams. But it seems that the benefit of teams could really enhance the work product for both product marketing and web marketing groups. Either because of limited people resources or different levels of experience most groups seem to default into workgroups. In some cases I wonder if groups have even considered functioning as teams. Teams where multiple product marketing or web marketing individuals work together on a launch or a pilot project. A team where each member provides a different viewpoint and skills that enhances the project. In addition, breaking out of the siloed work tasks and really working with your peers just seems like it could be more fun.

Here is a great HBR article on teams.

What have you seen more commonly used workgroups or teams? Is it possible for managers to make a shift towards teams or are resources to constrained these days?
