Step 1: Define leadership:
Leadership is the process of influencing the behaviour of people so that they work willingly towards a common goal.
Its features follow from this meaning.
Step 2: Feature 1: Influence on others:
A leader influences the behaviour of followers through example, guidance and persuasion.
People follow because they want to, not because they are forced.
Step 3: Feature 2: Common goal:
Leadership works towards goals that are shared by the leader and the followers.
It brings all efforts together to reach that goal.
Step 4: Feature 3: Leader-follower relationship:
Leadership exists only where there are followers.
It depends on the trust and understanding between the leader and the group.
Step 5: Other valid features:
Leadership is a continuous process and it depends on the situation. A style that works in one case may fail in another.
Final Answer:
Any three: it is a process of influence, it aims at a common goal, and it rests on a leader-follower relationship.
