Meredith Belbin and others have popularised the notion that we can't be all things to all people. No individual can therefore attain perfection – they will always have an Achilles Heel. On the other hand, a skilfully-assembled team, consisting of individuals who play to one another's strengths and cancel out one another's limitations, can get somewhere near perfection. However, even the best and most effectively-functioning of teams could be better. No team is perfect, even if it is already doing well. We can help teams improve still further. The great thing is that making this happen is often a lot of fun – entertaining as well as educational. Let us show you how.
