The paper discusses procedures of quality assurance in computerized information systems, and is composed of two parts:
The study compares between the different users of information systems, who are divided into three sample groups: students, academic staff and academic secretaries.
All three groups evaluated the two information systems based on a set of quality metrics.
There are two main findings to the paper:
These findings can lead to the conclusion that building a system on the basis of an orderly procedure in general, and on the basis of a specification document combined with UML in particular, is expected to yield a system of higher quality. An additional conclusion is that it is better to identify all the system users and analyze their requirements during the specification phase rather than focus only on the main user. This leads to a system with a higher level of correctness and with fewer changes to the system in late life cycle phases, which are very costly.
