CORRECTIVE AND PREVENTIVE ACTIONS.

Corrective and preventive actions are an element of the quality system and correspond to clause 4.14 of GOST R ISO 9002-96.

The purpose of corrective action is to eliminate or minimize recurrences of nonconformities.

This element of the quality system covers the following procedures regarding product and quality system nonconformities:

Determining corrective and preventive actions to eliminate the causes of actual and potential nonconformities;

Determination of responsibility that the corrective and preventive actions taken are adequate to the problem;

1. When carrying out final control, products are accepted by quality control workers at the quality control post in accordance with the requirements of current technical documentation (drawings, technical processes, specifications, instructions, standards).

The product is presented by an adjuster or shift foreman, who must personally verify that the product complies with the technical documentation.

2. If the quality control inspector detects the first non-compliance with the established requirements in the presented products, the inspector is obliged to stop further inspection of the batch and return it to the contractor for processing and elimination of the discrepancy with the entry in the “Quality Quality Control Products Delivery Log from the first presentation” (hereinafter in the Journal). A tag indicating the discrepancy, the date, the signature of the quality control inspector and the note: “For secondary presentation” is attached to the container with the products. The deadline for secondary presentation is determined in each specific case by the control foreman together with the workshop foreman and is noted in column 12 of the Journal with the workshop foreman’s signature on approval. The column also indicates the name of the performer whose quality mark has been reduced.

3. The quality control inspector is prohibited from rejecting parts, assembly units, products during the process of product acceptance, as well as accepting products in the following cases:

If the first three details were not presented;

Lack of cleanliness and order in the workplace;

The presence of defects in manufactured parts, as well as dirt and chips on parts;

Lack of drawings and technical processes.

4. If the quality control inspector detects inconsistencies with the requirements of technical documentation in the presented batch of products, the worker, in the presence of the foreman, is obliged to personally sort them out and present them separately to the quality control employee to draw up a defect report.

5. Workers transferred to self-control are given the right to hand over manufactured products without inspection by the quality control department. Quality control department employees carry out inspection quality control of products with a personal stamp.

6. The secondary presentation of finished products (parts, assembly units, products) for acceptance to quality control department employees is carried out after providing them with a report with the permission of the workshop manager. The report is drawn up by the workshop foreman addressed to the workshop manager after the batch has been sorted and deviations from the current technical documentation have been eliminated and is stored in the Quality Control Department along with the Logbook.

The workshop foreman fills out column 13 “Measures taken or decisions to eliminate deviations” in the Journal according to Table B.

For parts that have deviations from the current design documentation that do not affect the performance of the products, a Permission Card is issued by the department that allowed this deviation.

7. The third presentation of products for acceptance to quality control workers can be made by the shop manager after presenting a report to the supervisory foreman with the permission of the plant director or chief engineer. In this case, the workshop manager must provide a written explanation in any form about the reasons for returning the products and about the measures taken to eliminate defective products.

8. The results of acceptance of finished products during final control are reflected in the “Log of delivery of quality control products from the first presentation” (Table B).

9. If the control results are positive for the accepted products, the quality control inspector puts the quality control stamp in accordance with the technical documentation for the products.

10. Products that have a deviation and a permit card for this deviation are also stamped by the quality control department. Products are branded with a distinctive mark if the “Permission Card” contains a special instruction from the head of the quality control department regarding the distinctive mark. The distinctive marking is a double stamp, a stamp with the letters “KR”.

11. If the worker (production foreman) himself identifies a non-conformity of the product and presents it for control separately from suitable products, such a batch is considered accepted from the first presentation, and a defect report is drawn up for the rejected parts with a note in the “Quality Quality Control Product Delivery Log” from the first presentation » on presenting the marriage and drawing up a marriage certificate in column 13.

Inspection and testing during production

Incoming inspection and testing

Control and testing

Quality control must confirm the fulfillment of specified product requirements.

It includes:

• incoming inspection and testing;
• intermediate control and testing during the production process;
• final (finish) control and testing;
• permission to ship products;
• inspection and test reports (recording of inspection and testing data against pre-defined product acceptance criteria).

The supplier shall establish and maintain documented inspection and testing procedures to verify that specified product requirements are met. The required controls, tests and protocols should be detailed in the quality program or documented procedures.

1. The Supplier must ensure that incoming products are not used or processed (except as described in paragraph 3) until they have passed inspection or any verification of compliance with established requirements. The audit should be carried out in accordance with the quality program and/or documented procedures.

2. When determining the scope and nature of incoming control, the scope of management work carried out directly at the subcontractor’s enterprise and recorded evidence of ensuring compliance with the quality of supplies should be taken into account.

3. Where supplied products are sold prior to inspection due to the urgency of production, they should be clearly identified and recorded so that they can be immediately returned or replaced if they do not conform to specified requirements.

The supplier must:

• control and test products in accordance with the quality program and (or) documented procedures;
• store products until appropriate inspections and tests have been completed or required reports have been received and verified, unless the products are released under clearly defined return procedures.

The Supplier shall conduct all final inspections and tests in accordance with the quality program and/or documented procedures to provide evidence that the finished product meets specified requirements.

The quality program and/or documented final inspection and testing procedures shall require that all specified inspections and tests, including those specified either at product acceptance or during production, are performed and the results satisfy specified requirements.

Products should not be shipped until all activities specified in the quality program and/or documented procedures have been completed with satisfactory results and appropriate data and documentation are available and formally approved.

The supplier must maintain records confirming that the products have been subject to inspection and/or testing. These records must clearly indicate whether the product has passed or failed inspection and/or testing to meet certain acceptance criteria. If products fail inspection and/or testing, procedures for managing nonconforming products must be applied.

The protocols must indicate the unit that carried out the control or the official responsible for the release of the product.

Responsible for purchasing quality materials, semi-finished products and components, he must maintain a master set of all drawings, change sheets and other materials that may be required for existing orders. In addition, the chief inspector must have such a kit so that he can organize control upon receipt of the material. In addition, it is advisable for the chief controller to have an exact copy of the orders.  

When the final inspection reveals a large number of defects, the chief inspector should immediately discuss the matter with the inspector in charge of the current inspection, review all records and determine how the defective parts may have passed through assembly and on to the final inspection. Since the majority of defects are separated during routine inspection, this fact shows the shortcomings of the quality control system. The study of the reasons for product rejection during final control should be carried out by the chief inspector together with the production manager. A report on the results of the study of the causes of marriage (see Form 39) must be submitted to the director for consideration.  

Depending on the moment of implementation, technical control is divided into input (preliminary), current (intermediate) and final (acceptance). Incoming inspection is a check of materials, blanks, and parts before they enter production. For example, such control is carried out when preparing casing pipes for lowering them into a well (threaded connections, internal diameters and straightness are checked, the length of each pipe is measured). Current control is carried out after the completion of some part of the production process (production operation or group of operations). For example, checking the curvature of a vertical well. Final control is control of the finished product after completion of all production operations for its manufacture. For example, checking an oil well being put into operation.  

GOST 40.9001-88 establishes a model for quality assurance during design and (or) development, production, installation and maintenance GOST 40.9002-88 - a model for quality assurance during production and installation, GOST 40.9003-88 - a model for quality assurance during final control and testing.  

Final control is carried out upon acceptance of finished parts, assemblies or products that have been completely completed by the production cycle.

Let's give brief description certain types of quality control. Building materials, parts and structures arriving for construction are subject to incoming inspection. They must comply with state standards, technical specifications, working drawings and passports. Incoming control is carried out at procurement bases and construction organizations. Operational quality control is carried out on the basis of special instructions that allow completed production operations or construction processes to be controlled directly on the construction site. Operational control allows you to timely identify defects and take measures to eliminate them. Operational control is followed by acceptance output control with an assessment of the quality of construction and installation work performed by the team. Operational quality control is the most effective because it includes self-control of performers and helps to increase the responsibility of workers, units and teams for the quality of work performed. In addition, it ensures the identification and timely elimination of defects and their causes. Acceptance control is performed upon acceptance of finished construction products. Acceptance of completed construction projects into operation is usually carried out in two stages: preliminary, which is carried out by a working commission, and final, carried out by the state acceptance commission. Interim control is carried out upon acceptance of completed individual species works, for example, such as digging a trench, installing foundations, waterproofing, reinforcement laid in concrete, embedded parts, etc. These structures and types of work must be checked and accepted before they are hidden by subsequent work. An act is drawn up for hidden work. The list of structures subject to intermediate inspection is established by the project and technological maps for the work.  

Direct nationalization in all economic areas includes measures leading to the end of all foreign investment activities. They are usually motivated by political considerations. These measures are aimed at establishing final state control over the economy in the country and include the seizure of all privately owned means of production.  

Exported matches were transported without being subject to excise duty, but had to be provided with a stamp from the excise supervision and its certificates on the quantity of exported goods, and the excise tax was finally imposed only after the excise supervision had been provided with a customs certificate within six months about the actual export of matches abroad. The production, movement, sale and purchase of phosphorus were regulated by special rules of control by excise supervision.  

In the example under consideration, and we are talking about a machine-building enterprise with a single type of production, the marginal production costs included in the calculation of the management result from the sale of products represent the value obtained as the final calculation of the marginal costs for completed orders. Thus, here we take data on the actual used basic materials and components (for mass production - standard values, for external purchases - standard prices), as well as the actual time spent on development work, machining, assembly and technical control, the assessment of which is carried out on the basis of planned rates of standard costs (defined in the same way as in the example in Fig. 46 the value of 12.80 DM/standard-hour was determined). Which product groups contributed to the total coverage amounting to 1.3 million francs is shown on sheet 2 (Fig. 526).  

The Audit Chamber consists of the Council of Auditors (auditors) and the General Secretariat. The Board of Auditors has the right to check the annual final report on government revenues and expenditures, request documents and information necessary for the audit, make decisions on bringing violators of financial discipline to justice, etc. Audits are carried out by the General Secretariat and its member bureaus. The Audit Chamber exercises control after expenses are incurred or revenues are received into the budget on the basis of accounting and reporting materials. The main areas of control activities are checking the actual availability of state funds and other movable and immovable property of the state, establishing the legality of financial transactions, and monitoring compliance with financial procedures established by law. All public finance accounts, annually reviewed and approved by Parliament, are subject to the control of the Audit Chamber. The audit report prepared by the Chamber is submitted to Parliament by the government. In parliament, the audit report is considered by audit commissions created in both houses.  

It is important to understand that the mere fact that deviations exist does not mean that purchasing or production managers are personally responsible for them. Deviations (regardless of their level of detail) only indicate a problem area, but without further analysis they are not final proof of the personal responsibility of a particular manager for the imbalance that has arisen. Detailed identification of deviations can only help identify the official who can best respond to changes in the situation and begin to correct the situation. Let us note that using the budget for the purposes of control and persecution of managers is unlikely to find support among the employees of the enterprise, and therefore is unlikely to be a sufficiently effective method of cost management.  

Production departments are responsible for fulfilling the production plan, hence there may be a tendency to use material that does not fully or partially meet the requirements for it, which can be costly for the enterprise. Let's assume that the batch of parts at the third stage of production did not fully comply technical requirements, but was received for further processing. During the final inspection in the quality control department, it turned out that this batch of parts could not arrive and the assembly or the customer rejected the entire batch accepted by the control department. All the work, materials, and time were wasted. As a result, the company suffers a loss and fails to complete the order.  

However, in some cases, the production of parts can be so large and the products so cheap that it is economically advantageous to have a relatively higher percentage of defects in order to provide a larger quantity of suitable products. At the same time it will decrease production time, but the inspection time will increase, since a longer final inspection will be required to separate defective products from acceptable ones. In this case, the chief inspector must (take into account the cost of the final manufactured product, the cost of production, etc., determine the frequency of inspections (and the permissible percentage of defects, and also establish a list of all product parameters that require inspection. He must give the inspector the right to stop during the current inspection production in any operation where too many defects occur.  

Economic managers, economic and technical services, as well as public organizations of production associations and enterprises use analysis methods in order to draw up a scientifically based plan or commitment, to eliminate bottlenecks in production, to identify and mobilize on-farm reserves, to objectively assess labor results, and sum up competition results. , justification for economic incentives, to monitor the implementation of state plans, the safety of socialist property, and compliance with state and economic discipline. For example, when assessing economic activity and approving the size of incentive funds, special commissions carefully analyze performance indicators, identify the results of the influence of external factors that do not depend on the activities of the production team, facts of violation of economic discipline, failure to fulfill economic contracts, etc. Only based on the results of the analysis taking into account all the positive and negative reasons affecting the reporting indicators, a final assessment of the work is given.  

A characteristic feature of assembly production is the almost complete absence of final product defects, however, the costs associated with correcting defects in these workshops are relatively high. This feature poses special challenges for technical control, which is particularly difficult in assembly shops.  

CONTROL COSTS - The costs incurred by a company in monitoring to avoid the production of defective products fall into two main categories. The first is the costs of prevention or preventive costs, i.e. costs of pre-production activities aimed at preparing quality instructions and production descriptions, vocational training, planning the production process and collecting data on product quality. The second category is estimated costs. These are the costs of eliminating defects after the product has left the production chain but has not yet reached the consumer. These include final inspection of finished products, in-process inspection, and laboratory testing.  

Control over the quality of manufactured products, their compliance with standards and technical specifications, registration in the prescribed manner of documentation for accepted and rejected products, as well as control over the removal from production of finally rejected products  

Stationary control points should be created where the most dangerous and responsible areas roads. This is usually done after the development stage - acceptance testing of prototypes after the stage technological training- qualification tests, as well as acceptance tests, input and final types of control, inspection control of the production process.  

In 1924, Walter Shewhart used statistical methods for quality control purposes and laid the foundation for statistical sampling and process quality control. The problem of interchangeability of parts put forward by Whitney has found its final solution. Manufacturing technology requirements, driven by established tolerances and specifications, could be analyzed from a cost-benefit perspective. Shuhart's works revealed the need to represent production as a system. Over time, it has become apparent that factors such as product design, materials, equipment, worker skills, employee attitudes, labor turnover, and working conditions interact with consumer demands for product quality and pricing, as well as financial issues. One of those who paid attention to this was W. Edwards Deming (1950). He believed that management should help improve working conditions and work processes and improve the quality of manufactured products.  

The workflow of the quality control department in production is simple: if the product meets the specified parameters, requirements and technical conditions, i.e., delivery documents, it is considered suitable and goes into sale; if it does not comply, it is considered a final or correctable defect. With the complication of products and the expansion of their range, there was a continuous improvement in the control methods used by the quality control department from the simplest manual measurements to complex instruments, from checking each product, part - to
