I have worked for many years as a manager and executive of one of the largest companies in the country. My specialty has been building teams, and since leaving in 2000, I have focussed my consulting efforts on helping small and medium sized business leaders to recruit, build and manage teams of people. I offer this as background for the following comments.
Many teams in racing seem to miss the fundamental point of most teams: that "projects" (e.g. winning a championship) are about cooperative human effort, and not the money, time, or other resources you throw at them. All successful projects have some common elements such as a clear vision of the outcome, frequent and open communication, talented people in the right roles, and so on. Not all successful teams come to success with the exact same mix or the same style, but every one of them is dependent on the people to get them done.
Building an excellent team is tough, and is rarely done without "breaking some eggs" as another poster put it. Chemistry does play a role, although it is often overstated. I've found that most "chemistry" issues are really communication problems in disguise. Some people say too much or in the wrong way, others say too little or lash out passive aggressively. I've found that fixing most teams is at least 50% fixing the way people communicate.
I do not know Lucas Racing as a team (although I'd be glad to help), and certainly we here don't know enough to speculate on exactly what happened. But I do know things that support both sides of this situation: a) as a team leader, you have to frequently "cut your losses" and move out people who aren't working, and to do it quickly. However, b) you also have to make changes in a way that is open, honest, and respectful for all concerned or you risk long-term team health issues.
I certainly wish Lucas Racing all the success in the world, but I remind they (and everyone here) that treating others with respect, honesty, and frankness goes a long way to building teams that work well.
