COMMUNICATION is a key leadership skill that can determine whether a leader is successful or not. A phone call by the US President can lead to an official inquiry just as a tweet with 140 characters can cause a Twitter storm around the world. Effective communication is so critical that even a gifted public speaker like the former US President Barack Obama would rely on teleprompters to ensure that his speeches landed exactly as intended with every word just right. Speechwriters and editors are on staff to help leaders craft their message.
