I'm trying to be as clear as I possibly can. What measure do you use to determine that?
Take, for example, a department with customs operations that has trouble hiring staff or a department that operates ships. The data for those departments will differ from the data of other institutions, despite the fact that the deputy head may have done more than the deputy head of another department in order to address the shortcomings. Should I tell that deputy head that their organization is in the bottom 10?
