“Management is doing things right; leadership is doing the right things.” - Peter Drucker
To differentiate a manager from a leader is to differentiate goodness from greatness.
In today’s society, there is a surplus of qualified managers. Focusing on productivity, ensuring the execution of tasks in the most efficient way is what managers do best. Their focus on performance improvement, maximum efficiency, and present concerns rather than a future vision.
Leaders are focused on people, not just productivity. They are more concerned with the essence more than just the end result.
The above chart takes a look at some of the differences between leaders and managers; there are quite a few. Though there are definitely stark differences between leaders and managers, the roles are not mutually exclusive.
There is a need for both managers AND leaders. It is important to focus on the bottom line of and organization, but it's even more so important to have vision, develop individuals while strengthening the organization, and inspiring trust. Both management and leadership are important to an organization. Initially, it is important to establish a sense of trust, innovation, and originality. For the sustainability, it is also important to administer and focus on productivity and results.
