Based on my experience, one of the challenges of an enterprise system after it is set up is the system has some functional defects during operation time or causing outage. Since the system is cross disciplinary, none of the experts have enough knowledge to determine where the problems are. Since the impact of IT system failure can cause millions of dollars lost, no one would like to bear responsibility. Instead of accepting the problem, people from different department point fingers at each other, saying this is the other person's problems. You can see 30 people on a phone call with several directors, just to solve one technical problem. With good operational and compliance process, we hope we can mitigate this kind of situation to a minimum.
