The leadership approach that i like the most, Situational Leadership. It requires the leader to adapt his style to different situations. Employees move back and forth across the development continuum and leader has to adapt his style to meet the development level of employee. I wrote a short white paper last year on this: https://mvenkatorg.files.wordpress.com/2019/09/situational-leadership-1.pdf
If Leaders are those who give vision, direction, inspire people, setting examples and building teams then who are managers? What managers do in organizations? Managers are those who manage the organizations resources efficiently and effectively. They maintain the steady state environment in the organization. Managers are good administrators, and are good at performing routine tasks.. But can managers become leaders? Yes, indeed. Managers become leaders when they give direction, set objectives, inspire people and perform all other functions of leadership (like transformation activities), and when their personality and character is accepted by others in the organization. Leadership and management are overlapping concepts, resulting in little confusion, to some. Leaders need not necessarily be only at the top. Leadership can be at all levels, Strategic, Operational, Team Level.
“The higher the self esteem of a leader, the more likely it is that he or she can inspire the best in others. A mind that does not trust itself cannot inspire greatness in the minds of colleagues and subordinates” – Dr.Nathaniel Branden
“Twenty first century leadership relationship dynamics are from the bottom up rather than the top down; from the outside in, rather than the inside out” – James M Strock
