"Leadership is lifting a person's vision to high sights, the raising of a person's performance to a higher standard, the building of a personality beyond its normal limitations" (Drucker, 2012, p. 138).
Similar to the conductor of an orchestra, executives should support individual employees
in order to develop their (virtuoso) abilities,
on the other hand, unite the employees into a team that works together and
develops more than the sum of its "individual parts" (by Drucker, 2012, p. 295 f.).
