Leadership

Definition
The WIKI says: 

Leadership has been described as “a process of social influence in which one person can enlist the aid and support of others in the accomplishment of a common task". Other in-depth definitions of leadership have also emerged.

Leadership is "organizing a group of people to achieve a common goal". The leader may or may not have any formal authority. Studies of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values,charisma, and intelligence, among others. Somebody whom

people follow: somebody who guides or directs others.

Corporate Leadership Styles

The organizations generally try to show some distinct style of leadership in order to distinguish themselves among peers. They can be focused on-

Quality

Cost

Profit

Market Share

Ethics

People

Sustainability

Innovation, etc.

to leverage their advantage.

TATAs cash on their ethics image (innovation with NANO too) . RIL uphelds their cut-throat persona. HCL has this employee first attitude. 

 Manager and a Leader

Manager and leader are two completely different roles, although we often use the terms interchangeably. Managers are facilitators of their team members’ success. They ensure that their people have everything they need to be productive and successful; that they’re well trained, happy and have minimal roadblocks in their path; that they’re being groomed for the next level; that they are recognized for great performance and coached through their challenges.

Conversely, a leader can be anyone on the team who has a particular talent, who is creatively thinking out of the box and has a great idea, who has experience in a certain aspect of the business or project that can prove useful to the manager and the team. A leader leads based on strengths, not titles.

The best managers consistently allow different leaders to emerge and inspire their teammates (and themselves!) to the next level.

Changing Leadership Styles

  Leadership can and should be situational, depending on the needs of the team.Sometimes a teammate needs a warm connect. Sometimes the team needs a visionary, a new style of coaching, someone to lead the way or even, on occasion, a kick in the bike shorts. For that reason, great leaders choose their leadership style like a golfer chooses his or her club, with a calculated analysis of the matter at hand, the end goal and the best tool for the job

Here are the six leadership styles Goleman uncovered among the managers he studied, as well as a brief analysis of the effects of each style on the corporate climate:

The pacesetting leader expects and models excellence and self-direction. If this style were summed up in one phrase, it would be “Do as I do, now.” The pacesetting style works best when the team is already motivated and skilled, and the leader needs quick results. Used extensively, however, this style can overwhelm team members and squelch innovation.
The authoritative leader mobilizes the team toward a common vision and focuses on end goals, leaving the means up to each individual. If this style were summed up in one phrase, it would be “Come with me.” The authoritative style works best when the team needs a new vision because circumstances have changed, or when explicit guidance is not required. Authoritative leaders inspire an entrepreneurial spirit and vibrant enthusiasm for the mission. It is not the best fit when the leader is working with a team of experts who know more than him or her  
 The affiliative leader works to create emotional bonds that bring a feeling of bonding and belonging to the organization. If this style were summed up in one phrase, it would be “People come first.” The affiliative style works best in times of stress, when teammates need to heal from a trauma, or when the team needs to rebuild trust. This style should not be used exclusively, because a sole reliance on praise and nurturing can foster mediocre performance and a lack of direction.
The coaching leader develops people for the future. If this style were summed up in one phrase, it would be “Try this.” The coaching style works best when the leader wants to help teammates build lasting personal strengths that make them more successful overall. It is least effective when teammates are defiant and unwilling to change or learn, or if the leader lacks proficiency.
The coercive leader demands immediate compliance. If this style were summed up in one phrase, it would be “Do what I tell you.” The coercive style is most effective in times of crisis, such as in a company turnaround or a takeover attempt, or during an actual emergency like a tornado or a fire. This style can also help control a problem teammate when everything else has failed. However, it should be avoided in almost every other case because it can alienate people and stifle flexibility and inventiveness.
The democratic leader builds consensus through participation. If this style were summed up in one phrase, it would be “What do you think?” The democratic style is most effective when the leader needs the team to buy into or have ownership of a decision, plan, or goal, or if he or she is uncertain and needs fresh ideas from qualified teammates. It is not the best choice in an emergency situation, when time is of the essence for another reason or when teammates are not informed enough to offer sufficient guidance to the leader.

The Point is if you take two cups of authoritative leadership, one cup of democratic, coaching, and affiliative leadership, and a dash of pacesetting and coercive leadership “to taste,” and you lead based on need in a way that elevates and inspires your team, you’ve got an excellent recipe for long-term leadership success with every team in your life.
