Decision-making and problem-solving
As stated in a Harvard Business School article, one of the key areas in which every manager should excel is decision-making. The ability to make quick and effective decisions and to detect and solve problems, along with knowledge of decision-making methodologies, are essential to success in managing people.
Leading people is 85% about communication. Therefore, it is imperative a manager continuously educates themselves in this area and learns how to communicate effectively on a collective and individual level with all kinds of people.
Effective organisation of one's own time as well as the ability to plan the capacity of the team are indispensable skills for any manager. New methods, tools and ways of organising your own and your team's time are always being developed, so it is essential to keep educating yourself in this area.
A manager is often presenting something, be it the team's results in front of management, an unpopular decision made by senior management in front of team members, or a witty speech at a staff Christmas party. So it is good not to stumble in this area.
Trends and developments in the team's field
Of course, the manager must also be aware of trends in the area in which the team is involved. This is the only way to know how best to move the team forward and not allow it to stagnate.
There are a number of project management methodologies. A knowledge of these is useful for any manager; therefore, it is necessary a manager in the project management field further develop themselves.
