If we're discussing business leadership then I think that comment is not appropriate across the board: let me explain. If your company is one that, using an example I understand a bit, consulting oriented, then, yes, teamwork for projects/meeting client commitments etc. etc. is essential. But for where the company is going, long term goals, meeting payrolls, then I think the team rapidly whittles down to the one or two responsible individuals. Making any sense? Guess the no i in team slogan, for me, ignores the need for/role of leadership.
