Software Quality: The User's Point of View

In this paper is presented a methodological approach for the measurement and the evaluation of users' opinion for a software product. The methodology is general and applicable for every product and, as a concept, in every situation. The basic principle for the methodology is that each user's opinion should be evaluated in analogy to this user's qualifications in respect to computers in general, to this particular product and to the application automated by this. Therefore, the measurement and the analysis of the users' qualifications is performed before users are asked for their opinion about the product. Afterwards, the users will be asked their opinion about the product. This opinion counts equally to their pre-measured qualifications. In addition, in this paper are presented some techniques about how to set-up customized questionnaires, about how to collect and analyze the measurements and about how to overcome human aspects related to human disapproval, or even refusal to measurements.
