In his blog, Bob Warfield points out some of his key findings about developer productivity:
-Keep team size small
-Make things modular so that you can keep teams focused
-Invest in communications tools and infrastructure
-Make sure there’s sufficient face time with in-person meetings
-Focus on team chemistry
Yes, many people have been faced with this relation between team size and results. It is correct that as team size increases, the challenges of communication and motivation also increase manifold. However, I believe that focus, passion and integrity would be the key for any great task. Remember, that man did not land on moon with a small team.
