Quality as object of management

Quality management is the establishment, providing and maintenance of a necessary level of quality of production at its development, production, the address, operation and consumption which are carried out by systematic quality control and purposeful impact on conditions and factors, influencing it (State standard specification 15467).

To operate quality - to mean to carry out the economic, organizational, technical and other actions aimed at quality providing production at all stages of life cycle of goods (introduction, growth, a maturity, demand maintenance).

In modern understanding activities for quality management cannot be effective after production is already made; it has to be carried out continuously during production, and also precede the process of production.

Quality management is based on the following principles:

focus - it is necessary to have the accurate purpose in the quality relation;

planned character - is planned set of actions in the field of quality which are subject to implementation;

continuity;

intensity - improvement of quality belongs to intensive factors of development of economy;

system approach;

complexity - the solution of problems of quality taking into account all aspects on which it depends;

optimality - aspiration to exact compliance of quality to inquiries of consumers;

continuous improvement - promotes competitiveness of the enterprise.

Quality management of production - a production management component in general, one of its properties, functions. Therefore it develops and carried out within the operating control system and consists in development of policy in the field of quality, to accurate and well organized work on detection of demand, creation, production and service of production. This branch of science according to the general theory of management operates with concepts "system", "Wednesday", "program", etc.

Quality except major factors and conditions of production is influenced by many random, local and subjective factors. To influence all these factors, to support an appropriate level of quality, the control system, that is set of measures of continuous impact on process of creation of a product is necessary.

Distinguish the operating and operated systems. The operated system is presented by various levels of management of the organization, firm, other structures; the managing director - creates and provides quality management.

Let's consider the main categories of product quality control.

The control system of quality of production relies on the following interconnected categories: object, subject, purpose, methods, means, functions, character of the administrative relations, etc.

Object of management - quality of production, set of its properties or their some part, group, separate property. It is necessary for the effective organization of product quality control that not only the object of management was allocated, but also other categories allowing to realize and organize better all process are accurately defined.

The subject of management - the operating bodies of all steps and persons urged to provide achievement and maintenance of the planned production level of quality.

The purpose of management - a certain level and a condition of quality of production taking into account economic interests of the producer and consumer, and also safety requirements and environmental friendliness; set of properties and a level of quality which should be set, reached and provided that they corresponded to nature of requirement and thus provided production efficiency and consumption, availability of the price to the consumer, normal prime cost and sufficient profitability of production.

Methods of management of quality - ways with which governing bodies influence production, providing achievement and maintenance of the planned state and quality of production.

Methods of management of quality can be divided into four groups: organizational, social and psychological, economic, organizational and technological.

Organizational methods - set of the methods promoting such organization of the operated subsystem which will provide the demanded quality. Carry to this group of methods administrative (orders, directives, resolutions, instructions, orders), disciplinary, providing motivation (establishment of responsibility and forms of encouragement), stabilizing, based on all-organizational and linearly - a functional regulation on the basis of norms, standards, explanations, consultations, introduction, cautions.

Social and psychological methods - set of ways of impact on spiritual interests of workers, formation of their motivations connected with ensuring the corresponding quality. Treat such methods: education and promotion of devotion to the enterprise, respect for itself as to the employee of this enterprise, pride of its achievements, forms of moral incentive.

Economic methods of management of quality - the ways of influence based on application of economic incentives and creation of a material interest in achievement of the set purpose in quality area. Also include in group of economic methods: financing of activity in the field of quality management; economic incentives of production, granting to consumers production and the services conforming to their requirements; planning of creation of the new and modernized types of production and services; pricing on production and services taking into account their level of quality; formation of funds of economic incentives of quality; use of system of compensation and material encouragement taking into account its quality on each workplace of a production system and a control system of quality in general; use of economic measures of impact on suppliers depending on quality of the services delivered by them to production and rendered.

Organizational and technological methods are subdivided into methods of quality control of process and production and methods of regulation of quality of process and production. The main place in organizational and technological methods is taken by systematic methods of management of quality.

Control facilities quality include:

office equipment, means of communication which use the governing bodies and faces operating performance of special functions in control systems of quality;

bank of the standard documentation regulating indicators of quality of production and organizing performance of special functions on quality management;

the metrological means including the state standards, measuring instruments;

the regulating documents of the state system of ensuring unity of measurements (GSI);

base of public service of standard help data on properties of substances and materials (GSSD).

The functions which are carried out by the enterprise concerning quality as object of management, following:

Rationing (standardization, certification, certification);

Technological preparation of production (sufficient logistics, high-quality seeds of plants, elite breeds of animals, high level of service, etc.);

Professional development of shots, stimulation, strengthening of responsibility for quality;

Control of the course of productions by means of information and methodological support.

The administrative relations in the field of quality are the relations of subordination (submission) and coordination (cooperation).

The relations of subordination are characterized by vertical communications of heads with subordinates and are defined by extent of centralization and decentralization of functions and problems of product quality control. At the level of the enterprise of the relation of subordination are under construction depending on its production structure and structure of a control system of quality. The administrative relations are based on a combination of one-man management, collective nature, stimulation of an initiative of members of labor collective, use of economic, moral and material incentives.

The relations of coordination are under construction by means of horizontal communications between the certain workers and the organizations entering interaction for the sake of providing a certain level of quality of production or its increase.

At the level of the enterprise product quality control can be organized by distribution of functions and tasks between divisions and workers or creations of special department of quality management. In organizational structure the divisions which are engaged in coordination of works on quality management can be provided. Distribution of functions of quality management between divisions depends on volume and nature of activity of the enterprise. In any option the head of the enterprise who is responsible for all its activity and economic results which cannot be high at bad quality of production has to perform the general management of a control system of quality.

Heads should recognize that the enterprise it is capable on bigger in comparison with last experience

Qualimetry

The assessment of a level of quality of object and classification of indicators of quality are considered in a Qualimetry.

Qualimetry (from armor. qualitas - what on quality and … a metriya) - the branch of science studying and realizing methods of a quantitative assessment of quality.

Main objectives of a Qualimetry: justification of indicators of quality, development of methods of their definition, calculation and optimization, improvement of standard sizes and parametrical ranks of products, development of the generalized indicators and justification of conditions of their use in problems of standardization and quality management. Any goods and services to which the concept "quality" is applicable can be objects of a Qualimetry. It can be production and service of the industry, agriculture, etc.

Starting position of a Qualimetry is that quality depends on a large number of properties of object. Besides, it is necessary to consider also conditions in which the product will be used.

Any production or service has a set of properties. Understand its objective features which are shown by production, operation and consumption as properties of production. Distinguish production and consumer properties of production.

All set of the properties created in the course of production belongs to the production. It represents potential quality. Consumer properties of production characterize only that set of indicators which is among the most important and significant for the consumer. This real quality of production.

Quality indicators - the quantitative characteristics of one or several properties of production considered in relation to certain conditions of its creation, operation or consumption. Quality indicators quantitatively cause degree of ability of production to satisfy certain requirements (for example, quality of tubers of potatoes is characterized by amount of starch).

It is possible to allocate simple (the weight, capacity, length, etc.) and difficult (non-failure operation, maintainability, etc.) quantitative characteristics of one or several properties making quality, respectively single and complex indicators of quality.

Each type of production is characterized by the quality indicators. According to GOST 15467 use the following groups of indicators (tab. 1).


Table 1

At an assessment of quality of domestic goods indicators are applied to the population: grade (foodstuff, production of light industry), group of complexity (household radio equipment), brand (cement, brick), category of quality (videotape).

In world practice for an assessment of degree of superiority of one part of production over another use gradation (a class, a grade) are the categories or the category appropriated to production having the same functional application but to which various requirements for quality are applied.

Classification of indicators of quality by various categories is presented in tab. 2.
