Fundamentally JT, in all those industries, the most effective ones are the ones where the Leader/Manager/Captain fosters development, openess and leadership practice while all the time delegating and maintaining the professionalism and expertise that is expected of them in their particular role. The LHS of a jet is no different.
In all those industries, the outcome relies solely on the individuals ability to lead a team. Just because you are the boss, doesnt mean you can lead a team effectively!!
If the team leader needs to make an urgent or critical decision then provided the team has been kept appropriately informed and consulted, that decision is going to be easier to make and more widely recieved!!
