That really is a difficult issue, but it is also a very important one.
In the past, we have often noticed that, when departments assess the performance of some of their programs, they measure only the aspects that are the easiest to measure, not necessarily the most important. Often, it is easy to measure a certain part of a process but that is not the entire process. It is therefore possible that there are problems in evaluating the results of the same program, although there is a way to measure only one aspect of it.
Departments have to focus on results. They must find an effective way of determining whether a program can provide the anticipated results. That is the first thing to do, I feel. Second, of course, they must have all the data they need in order to implement measures that allow the progress of a given program to be measured.
