As CIOs, some jobs are tougher than others. 

One of the most demanding is when you find yourself taking on a troubled IT department.  This isn’t a job for the faint of heart. Your job will be to repair  damage and put things back in order so that the company can realize the  importance of information technology. This will require a great deal of  time and effort on your part. The good news is that if you succeed,  you’ll be lauded as a hero. 

The bad news is that if you fail, your  washout could haunt your CIO career for years to come.
