To make a good leader, leadership qualities are required; these qualities vary in different situations, companies, and teams somehow. Most people only have one leadership style which would be fine if they could find a proper situation that acquires that style. It is quite bordered, though; however they also could be quite flexible on the way of being in leadership.
Flexible leadership, however, involves being capable of adapting one’s leadership style according to the situation and the state of the team – for instance: A leader could apparently take charge when a team is forming but playing the role of coach when a team is managing itself pretty well.

Perspective

How you approach leadership qualities will depend on how you are sorting out and looking at the subject from the perspective of an organization and/or an individual.
Organizations purpose to improve their performance by selecting and developing potential of individual within the organization. At the outset, the needs of the organization are usually defined well but the individuals, who may become leaders, are still unknown.
An individual’s perspective, somehow, is very different: the purpose is to develop into a position of leadership for the individual. You are who you are, and if your profile does not match that of the organization is seeking for, then your duty are to understand your own attributes or potential and find a new role or organization where your profile will be valued.
Conclusively, what makes a good leader? The answer depends on the context. Organizations need to find people who have what they are looking for. Individuals need to find organizations that are looking for what they have to offer.
