Practice of quality modeling and measurement on software life-cycle

The authors introduce quality metrics into the quantitative software quality estimation technique, embracing the quality estimate of design, as well as of the source code, in studying a quality quantification support system. They outline a quality quantification technique for this system, describe examples of both its application to actual projects and its evaluation, and consider its relationship conventional techniques for estimate indexing of T.J.
