Abstract: Procedure approach that is widely used in organizations allows to understand whether project team follow established process or not. But unfortunately this approach do not ensure problem identiication on the early stage and do not allow as to be sure in high quality of product.

Following to all established procedures do not ensure base for software qulity evaluation. Such approach depend on quality of procedure and qulity of its execution. So the main imperfection of this approach is in the fact that project managers do not have quantitative methods to evaluate quality of the product. The only one thing that is transparented for them is whether planned task were completes or not.

The approach described is based on quantitative management and help to resolve this problem. In the article testing process was choosen to demonstrate main principles of quantitative management approach realization that allow to establish quantitative goals, analyse processes and develop and implement corrective/preventive actions earlier.
