This paper presents a combined, high-level quality view of TL9000 handbook and ISO/IEC 9126 in the process of defining, measuring, evaluating and finally achieving appropriate quality of user-centered software products. In its practices-related part this paper discusses the benefits, which the use of TL9000 product operational (in-the-field) quality measures can bring to setting up, measuring and evaluating the quality of the software product being developed, through its entire life cycle.
