There is this corporate governance question rasied all the time if CEO and Chairman position should be held by the same person or different persons.
Different posts can hinder decisionmaking speed but gives the much needed perspectives to decision making.
But then how do actual people handle these processes. According to a survey about 80% of all organisations have only 1 person handling the same post and they also have 5% higher sales figure.
So if you want better performance better have one person as Chairman and CEO.
