While being proficient in all areas is optimal, it is not always realistic. Being good in the three main traits of leadership, decision making, and communication is the mark of an effective supervisor. Supervisors are responsible for the people aspect of the business. A supervisor must understand the people that work for them and be able to apply management principles to each situation. This involves communicating the job to be done, deciding who is to do the job, and leading the workers to the completion.
Effective supervision is the overall driving force behind the successful business.
All successful businesses have a supervisor that can lead the employees, make valid decisions, and communicate the goals of the organization. By doing the above, the supervisor creates the optimal workforce for the job at hand. Leadership gives the employees direction and someone that they can rely on when in need. Effective decision-making allows the employees to get the task done in a timely manner and in the order of importance. A great communicator will describe the task clearly so that there is no confusion and listen to any problems that is brought forth.
