Article describes the features and specifics of building the quality management system for machine-building enterprise, based on the requirements of the latest versions of normative documents. Structure of the generalized quality management system during the design, production and application of such products is presented on the basis of methodology of the process approach in conjunction with the "Plan-Do-Check-Act" Deming cycle. New approach is proposed for the construction of system for managing the processes of the product life cycle, which is based on consistently-parallel control of the set of stages of the enterprise life cycle.

Methodology for the system of engineering and managing the production of enterprise is presented, according to which it is necessary to carry out the following stages of creating and processing of quality information. The first stage consists in data collecting during the design and production processes. Generalized quality matrices for stages of designing, manufacturing and final inspection of the machine-building product are considered. At the second stage the FMEA analyzes the risks of potential types of product and process failures. At the same time, the matrix of quality is formed from a specific group of individual quality indicators - the so-called priority numbers of risk. As result, the comparison of received partial matrices with some reference matrices is carried out.

It is proposed to apply Ishikawa charts for determination of the causes of deterioration in the quality of products and processes and contribution factors. Example of typical technological process envisages the structure of constructing such a diagram and the properties of its elements. Four quality vectors for carrying out the necessary research are given. Reason for violation of quality of product during the FMEA-analysis is substantiated. At the third stage the data’s primary statistical analysis is obtained using Pareto charts, which provides the necessary corrective actions. Example of construction of this diagram is shown for typical rather simple technology based on the requirement to establish the main causes of defect appearance.
