Everyday work today requires from a manager much more than what was needed just a few years ago. The basic managerial job remains the same; get your company, project or idea moving forward into a brighter future, taking good care of the present. Only today that role must be exercised in a much more complex environment. One ingredient of this complexity is the fact that the manager must collaborate with dozens of overeducated people that have a notable expertise in their particular field.
This abundance of education and knowledge is fantastic, but comes along with great human challenges for anyone leading the project or organization.
