The fourth task is to manage. The scale is not fixed: your own business, a department, a line of work, an entire company — what matters is that this person makes the decisions and answers for them.
The field, meanwhile, can be any at all. Everything is open to the four, and the choice of industry is for it a question of taste rather than of suitability.
One condition is fundamental: the managing has to be done from the inside. The four must be part of what it leads — know the process, take part in it, have the final word. Remote leadership, where the person only receives reports, does not work for this task, and a business run that way falls apart.
The task is carried out when there is something that rests on this person and would not have come together without them.
