Answer: 10. Three high ranking bureaucrats who do not believe that the light bulb issue is their business. Three managerial levels who do not understand that their duty includes solving the light bulb issue. Two low level officers who do not believe that the light bulb should be replaced as soon as possible. One janitor who claims that he has already reported that the light bulb is burned out. One pissed-off (=me) Faculty, who believes that this is yet another perfect mismanagement example, and therefore conducted a full scale investigation in regard of the light bulb case.
Note: Case closed, finally the light bulb has been replaced today!
