A manager must have a honed skill set for both people management and Project Management. Managing people is challenging. It requires evaluating, making tough choices; giving feedback, understanding values and essentially understanding each person in your team to get the maximum output. It is very important to be able to positively influence your colleagues, get them to buy in to your goals and implement your strategy. A manager is an influencer and enforcer rolled into one. An effective manager is required to deal with subordinates and seniors with tact and diplomacy. Generally speaking management skills like Project Management, Strategic Thinking, Decision making, Negotiation, communication and leadership span across industries and sectors but there are some specific management skills which are specific to the industry the manager is working in.
