Software Project Cost Of Quality Models And Management Methods

The economic benefits of enterprises relate to a lot of factors, but the most important thing is the product quality and quality management. Especially for software industry, because of the particularity of the software product, the quality problem of the software product has been a focus of the whole society all the time. With the expansion of the quality content of the software, the analysis and control of the software quality cost become more difficult. Software quality cost means that relevant expenses of the expenditure to guarantee and improve software quality for enterprise, and the tangible and invisible lost incurred because of not reaching set quality level. However, the application time is relatively short in our country's development for concept of quality cost, lots of enterprises have not really implemented the quality cost management activity. Even more, the software quality cost has just started, the management of the software quality cost exists many questions such as the theory method lags behind, can't keep up with the needs of development in time.This text introduced the concept of the quality cost, analyzed its composition and current development of the domestic and international. On this basis, put forward in the current quality cost forms to the new-type quality cost formed. According to the characteristic of software project development, use the principle of fuzzy mathematics, proposed the calculation model of the optimum software quality level in design phase, calculation model of the proportion of best software quality cost. These two mathematics models both have good effectiveness and accuracy, with certain actual meanings. At the same time, Use real data to prove the calculation model and go on to result analyzing. Finally, according to total quality control concept and method, introduce overall theory development of software quality cost, that is, overall management of quality cost.As the important component of software quality control, management of quality cost of software being vigorous new developing field of our country, the views and model mentioned in the article also need our further investigating and discussion.
