We've all heard about hard skills and soft skills.
In reality, there is nothing “soft” about the skills needed to relate to people well enough to lead them. True leadership involves both hard skills and harder skills.
Leadership has its own set of occupational skills, such as the ability to synthesize data; the clarity to make timely and informed decisions; the capability to define priorities and goals; and the aptitude to see situations from a wide, organizational perspective.
On the behavioral side, leadership requires an exceedingly high degree of skill in working with and for others, holding others accountable to their commitments, and marshaling others to work together while following you into the future.
