What traits do they possess?
I feel a leader has to be honest because if they aren't, then their followers can't trust what they say, their actions and decisions. So basically the followers start to lose trust in the leader. A leader also has to be competent, which means they choose their actions on reason and moral principles and not on emotional desires or feelings. This will lead them to make proper decisions and not regret them. They also have to be forward-looking and set goals and have a vision of the future. They also have to know what they want and how they want to get it. Example, Lee Hsien Loong planned to build 2 Integrated Resorts (IRs) in November 2004. Now, almost 6 years later, his vision is starting to come true. Leaders also fair-minded by not being biased towards a group of people. They also have to be sensitive to the feelings, values, interests, and well-being of others. If not, the followers will not want to work with or follow what the leader tells them to do, thus creating a bad image of the leader.
How do you think a good leader manages crisis under stressful situations?
They should have a strategic vision and peripheral vision: look ahead, look around. Thus they can sense if a crisis will happen by looking for tell-tale signs. They should also have a strong team since success is always derived from the right people and teamwork. They also need to communicate constantly with people through meetings, E-mails, voice mail, Webcasts etc. They also need to have a strong internal compass. They should now what they need to do, but they also have to be flexible.
