I believe that leadership skills are necessary to become a successful project manager.
Part of being a good leader is to be organized. His organization skills will ensure the smooth operation of the project and will account for the numerous different aspects that involve any project. Furthermore, it is important to note that project managers usually take on multiple projects at a time and to be able to manage each project and oversee their completion, they must have good time and logistics management techniques. They must be able to find and utilize the method which would be most practical, cost-effective, least wasteful and I believe that this falls under the organization skills that a project manager must possess.
Another important aspect of leadership is being able to communicate. Being able to relate and talk to their co-workers in a way that is respectful and can be understood is an important skill that each project manager has. Other members must be able to clearly understand the vision and end goal of the project manager so that all members can contribute to the whole success of the project. Project managers must also be able to inspire their co-workers and push them to be their version possible. Furthermore, part of having good communication skills is becoming a good listener. They must be able to respectfully listen and take in opinions, suggestions, and other information that the other members will pitch in. A good project manager must be able to know his/her co-workers so that he/she can take advantage of their different skills that they can contribute to the project.
