Many task oriented CEOs claim success through their focus on task completion. They make employees accountable. They then micro manage to ensure they are on top of everything. This works in smaller companies where each member of the team is accountable to the 'boss'.
However, as companies grow, CEOs become more stretched by the 'always on' work environment. One-to-one conversations happen less frequently. There is less time. The task oriented CEOs can't cope and become overloaded with too many decisions. Business growth slows down. Everybody becomes frustrated.
