There’s this concept known as the Peter Principle, where leaders are promoted beyond their competency and have to “fake it till they make it.”
As it turns out, this is a very common phenomenon.
It happens at every level of leadership.
It would be unwise for a leader to pretend they know everything and that all decision-making has to come unilaterally through them. No one knows everything and it’s bad form to appear as such.
The better approach is to empower your people to be leaders themselves. Rely on their experiences and expertise. This is a much better approach that will lead to better morale, performance, and outcomes.
Leadership is a team sport.
