Heavyweight teams are characterized by their strong project focus, commitment, and accountability. These teams are typically led by strong project leaders who have the authority and resources to drive the project to success. They offer an integrated system solution and require a depth of resources and commitment from the organization. Therefore, a weak project leader and project focus do not describe a heavyweight team.
