If I had to pick one skill a manager has to have to be successful, I would pick interpersonal skills. I’ve dealt with plenty of managers over the years. Only one stood out. This one is in the company I work in now. He is by far the most amazing manager/individual/human being I’ve ever met. This is because of his interpersonal skills. He’s new to management but he’s had a huge impact already. He communicates so well with everyone, is always so nice and can turn any situation into a fun one. Another great skill he has is organization. He’s very organized with notes, meetings and schedules. He always plans ahead and makes sure he has enough time between events. He takes notes everywhere he goes and follows up using them. A successful manager is one that strong interpersonal skills and superb organization skills. Other skills are definitely necessary for the success of a manager, but I believe these are most critical.
