The efficiency of an IS
Engineering is about making things in a controlled way; information systems will not escape this much-awaited transition as their efficiency could be improved. To do so, we need indicators, measures, and a method to get the results on a given information system. Fortunately, there is a consensus on this in the field of expertise, as we will see now.
The measure of efficiency of a system
Since a system is a group of items working together toward a goal, as defined previously, measuring the efficiency of the whole means more than just knowing the efficiency measures of each item and summing them one way or another. It is often said that the value of a good information system is much more than the value of each of its moving parts and that the most positive effects come from their interactions.
A good way to measure the efficiency of an information system is to evaluate how much time and money it helps save on the functional processes it supports. However...
