Is your typical communication channel to your direct reports not working? Are people dropping the ball, doing the wrong thing, or not understanding your stated vision for the company? Your EQ might need a little polishing. First - Run out and buy Daniel Goleman's Working With Emotional Intelligence. And I mean RUN.
Why? Leaders (like you) are not defined by their IQs or even their job skills, but by their "emotional intelligence": a set of competencies that distinguish how people manage their feelings, interactions and communications. This book explains what emotional intelligence is and why it counts more than IQ or expertise to excel on the job.
My Take: I've always found corporate leaders who have used those IQ skills that got them where they are today will find their IQ skills will not keep them in the position that they have attained. That's why many C-Level executives have a typical job duration of 2-3 years (or shorter) at a company.
Why? When you are moving up the ladder, you tend to use more IQ (Intelligence) than EQ (Emotion). You need to get work done. You need to meet deadlines. You need to show results. The closer you get to the top, the less IQ you use and the more EQ you leverage to manage people, communicate strategies, etc. Unfortunately, when you are at the top, your position is ALL EQ and almost no IQ - and that is where most C-Level executives fail.
Working With Emotional Intelligence will help you address this.
