My colleague and friend Mike Caspar has posted another insightful article on his blog: Do not create unnecessary fear and animosity with Development Managers. From the article:
As teams grow, they build confidence and seem to become self-contained, and almost insular to some. This is normal and is not a sign of dysfunction. This simply indicates that the team is starting to have self identity. They are starting to act as a team. This is a good sign…. As the teams become more effective, the Development Manager feels more loss.
