Get rid of the dead wood

A coworker and I were discussing the nature of IT in large organizations. I firmly believe that software can be created and deployed by large organizations but better software and better service comes from small organizations. Many experts will tell you that the amount of communication increases rapidly as team size increases. That is a factor yes, but my thought is that big companies have a larger percentage of deadwood. Most large companies have so many people that are arranged in silos and want to do very little if it is outside their domain or comfort zone. Most small companies have people that wear multiple hats and aren't afraid to learn something new or roll up the sleeves to get it done. That being said I have worked in teams in a big company that were competent and completed on time and under budget. Why is this like this? It's the nature of how big companies want to manage their staff. They offer buyouts (politically correct choice) to get rid of the deadwood and guess who takes it... the people that get the job done. Why? Because they can thrive elsewhere and they know it. The deadwood is comfortable staying where they are at (and they know it). Think about it.
