I’ve met many people who consider themselves leaders OR managers in my career…and I’m still pretty young. What I have NOT met a lot of are people exemplify the full spectrum of competencies.
The focus on leadership lately is not bad per se, but perhaps the pendulum has swung too far. Managers have focused so much on being collaborative and consensus building that they have forgotten or are unwilling to make decisions, and yet they have not yet learned how to release decision making to their team members. So either decisions take far too long to make or they never get made at all. And in the world of accelerated change this can be a major hindrance.
I see the challenge coming from the contrast of knowledge and wisdom. As I interpret those two terms, knowledge is about information and learning of a topic or principle; wisdom is about balancing when to apply that knowledge and when not to. So simply knowing how to collaborate or achieve consensus is not enough if you think it is always appropriate. (See Over-collaboration) Even more dangerous is when collaboration and consensus are confused.
Managers need to be able to make decisions, regardless of their level. And they need to know when their team needs to make decisions. Developing leadership and management skills together and knowing which tool to use is what makes you effective. If you are not good at one, your efforts at the other will probably suffer. As an example, if you struggle with delegating completely and giving ownership to your employees (management skill) then setting a vision for them to move towards (leadership skill) may leave them frustrated. It would be like setting the rabbit running but keeping the greyhounds on a leash.
It’s not about how leaders and managers are different, that just creates a false belief that people are (or should be) one or the other. Ultimately, it is a false differentiation and needless labeling. Regardless of what you call yourself, you need to be good with people if you work with others and you need to be effective with processes and things if you manage a function.
