T here are a lot of matters involved in the Quality sector. Our conclusion is that it cannot be considered as a technical matter, as it involves more than technical skills. This means that all the processes (business and other) must be developed on a Quality framework.
Quality doesn't mean a lot if it is related to one aspect in particular. Administrative processes, IT processes are different and for each there must exist a way of measuring this level of quality. The measure is increasingly used to demonstrate and to assess the value of something. This is also true when considering the value of ICT. It is increasingly translated in numbers because numbers are easier to compare. Of course, this bring us in another subject which is the decision process. In fact, to make short a long story, deciding means mainly comparing numbers (whathever they represent) and choosing among a set of alternatives based on the result of the comparison. In general, the way of choosing is based on "I choose the alternative A because compared agains B and C, A is better".
All the problem is deciding what means "A is better than B and C".
As such, when measuring, two schools are to be considered: The US school and the European one. They are different in that the US approach translates everything in financial decisions. A is better than B means that A brings in return more than B. This also means that it has been found a function to translate A and B in financial terms.
The European approach also compares two numbers, but when translating A and B in numbers, it means that it has been found a mathematical function to translate A and B. As a consequence, the comparison means that A is better than B if the function representing A is greater than the function representing B.
