The five tools of quality management, also known as the five tools of quality control. Including:
1. Statistical Process Control (SPC, Statistical Process Control);
2. Measurement System Analysis (MSA, Measurement System Analyse);
3. Failure Mode & Effect Analyse (FMEA, Failure FMEA (Failure Mode & Effect Analyse);
4. Advanced Product Quality Planning (APQP, Advanced Product Quality Planning);
5. Production Part Approval Process (PPAP, Production Part Approval Process).
Advanced Product Quality Planning (APQP)
First, SPC
SPC is a manufacturing control method, is the manufacturing control project, according to its characteristics of the information collected, through the process of ability to analyze the process standardization, to explore the process of abnormalities, and immediately take measures to improve the process to return to normal.
The use of statistical methods to monitor the state of the process, to determine the production process in the control of the state, in order to reduce the variation of product quality SPC can solve the problem:
1. Economy: Effective sampling control, do not have to check the whole number of defective rate, to control costs. Make the process stable, can control the quality, cost and delivery;
2. Early warning: abnormal trends in the process can be immediate countermeasures to prevent the whole batch of bad to reduce waste.
3. Distinguish special causes: as a reference for regional problem countermeasures or management system improvement.
4. Make good use of machines and devices: Estimate the capacity of machines, and properly arrange appropriate machines to produce appropriate parts.
5. Improvement assessment: The process capability can be used as an indicator for comparison before and after improvement.
Second, MSA
First, to ensure the accuracy/quality of the measurement data, the use of Measurement System Analysis (MSA) methodology to evaluate the measurement system to obtain measurement data; second, to ensure that the use of appropriate data analysis methods, such as the use of SPC tools, design of experiments, analysis of variance, regression analysis, etc. MSA (MSA) (the). MeasurementSystemAnalysis) analyzes the resolution and error of a measurement system using mathematical statistics and graphical methods.
MeasurementSystemAnalysis (MSA) is to analyze the measurement system that can repeat the readings for each part, to evaluate the quality of the measurement system, and to judge the acceptability of the information produced by the measurement system.
Third, FMEA
In the design and manufacture of products, there are usually three lines of defense to control defects: to avoid or eliminate the causes of failure, to pre-determine or detect failures, and to reduce the impact and consequences of failures. FMEA is precisely to help us from the first line of defense will be the defects eliminated in the cradle of an effective tool. FMEA is an important method for reliability design. It is actually a combination of FMA (Failure Mode Analysis) and FEA (Failure Effects Analysis). It evaluates and analyzes various possible risks in order to eliminate them or reduce them to an acceptable level based on existing technology. Timeliness is one of the most important factors for the successful implementation of FMEA, which is an "ex ante" rather than an "ex post" behavior. To be most effective, FMEA must be conducted before failure modes are incorporated into the product.
Fourth, APQP
Advanced Product Quality Planning (or Advanced Product Quality Planning and Control Program) is part of the QS9000/TS16949 quality management system. Definition and other points: Product quality planning is a structured approach to identifying and developing the steps needed to ensure that a product satisfies the customer. The goal of product quality planning is to facilitate liaison with everyone involved to ensure that the required steps are completed on time. Effective product quality planning relies on top management's commitment to the goal of striving for customer satisfaction.
V. PPAP
PPAP Production Part Approval Program (Production part approval process) PPAP Production Part Submission Guarantee: Mainly production part size inspection report, appearance inspection report, functional inspection report, material inspection report; plus some parts control methods and supplier control methods; Mainly manufacturing companies require suppliers to submit their products in a timely manner. Manufacturing enterprises require suppliers to submit products to do ppap file and the first piece, only when ppap file all qualified to submit; when the project changes must also submit a report. PPAP is a control program for production parts, but also a management method for quality.
Reference:
A lot of quality management software is just a simple SPC software, mainly to try to experience their own to know whether it is suitable for their own use, our company (auto parts) in the introduction of quality management software, on the search for a lot of quality management software, and ultimately finalized the Richeer QMS quality management software, modules or more comprehensive, relatively simple to operate, because some of the software is just SPC, simply can not deal with incoming, outgoing and outgoing materials, the quality of the software, and the quality of the software. The module is still comprehensive and relatively simple to operate, because some softwares are only SPC, which can't deal with incoming materials, shipments and customer complaints.

What are the quality management tools and methods for continuous medical improvementThe so-called seven tools commonly used in total quality management is to carry out total quality management activities, used to collect and analyze quality information, analyze and identify quality problems, control and improve the level of quality of the commonly used seven methods. These methods are not only scientific, but also practical, as a team leader should first learn and master them, and lead the workers to apply to the actual production.
First, the checklist
Checklist, also known as the survey form, statistical analysis form. Checklist is the QC seven practices in the simplest and most used practices. But perhaps because of its simplicity and not pay attention to, so the checklist used in the process of a number of problems.
The purpose of using the checklist:
Systematically collect data, accumulate information, confirm the facts and information can be roughly organized and analyzed. That is, to confirm the presence or absence or whether what should be done has been done (to check whether there are any omissions).
Second, the ranking chart method
Ranking chart method is an effective way to identify the main factors affecting product quality.
Steps to make a ranking chart:
1, collect information, that is, in a certain period of time to collect information on product quality issues. For example, you can collect 1 month or 3 months or half a year and so on in the period of the waste or non-conforming product information.
2, layered, listed in the data table, that is, the information collected data, according to different issues for layered processing, each layer can also be called a special case; and then statistics on various types of problems (or each special case) the number of times repeated (i.e., frequency); according to the frequency of the size of the order of the data table from large to small, as the basic basis for calculations and graphs.
3, the calculation, that is, according to the information in column (3), accordingly calculate the percentage of each type of problem in the total problem, counted in column (4), and then calculate the cumulative percentage, counted in column (5).
4, make the ranking chart. That is, according to the information in the table above for graphing. It should be noted that the cumulative percentage should be labeled on the right side of each special case, and then from the origin, point to point with a straight line between the line, so as to make the Pareto curve.
Third, the cause and effect diagram method
Cause and effect diagram, also known as the characteristics of the main cause of the diagram or fishbone diagram. According to its shape, some people also call it a dendrogram or fishbone diagram. It is an effective tool to find the causes of quality problems.
Fourth, stratification method
Stratification method, also known as classification, is to analyze the impact of quality (or other problems) causes. We know that if a lot of different nature of the causes stirred together, it is very difficult to make sense of it. The way to do this is to categorize the information collected according to different purposes and to group together information of the same nature, collected under the same production conditions. In this way, can make the information reflect the facts more obvious, more prominent, easy to identify the problem, the right medicine.
Fifth, the histogram method
Histogram (Histogram) is the short form of the frequency histogram. It is a series of rectangles of equal width and unequal height to represent the information of the map. The width of the rectangles indicates the interval of the range of information, and the height of the rectangles indicates the number of information in a given interval.
Six, the control chart method
Control chart method is in the form of control charts to determine and forecast the production process, whether the quality of fluctuations in a commonly used statistical methods of quality control. It can directly monitor the process quality dynamics of the production process, with stable production, quality assurance, active prevention.
Seventh, the scatterplot method
Scatterplot method, refers to the analysis and study of the relationship between the information of the two factors, to control the quality of the product quality of the relevant factors of an effective method.
In production practice, there are often a number of variables **** in a unity, they are in contact with each other, mutual constraints, in certain conditions and mutual transformation. Some variables have a deterministic relationship between them, the relationship between them, can be expressed in terms of a function relationship, such as the area of the garden and its radius relationship: S = πr2; some variables but there is a correlation between them, that is, there is a relationship between these variables, but can not be accurately derived from the value of one variable to the value of the other variable. The two related types of information are listed, punched with dots on a coordinate chart, and then the relationship between the two factors is observed. Such a diagram is called a scatter diagram or correlation diagram.
How to apply PDCA management tools for hyperbaric oxygen quality managementWith the development of modern medicine, the use of hyperbaric oxygen is becoming more and more popular, due to the special unit of hyperbaric oxygen needed to pressurize the ship and its oxygen chamber of the tiny changes in the environment, in the process of treatment a little inadvertent, light is to increase the patient's pain, or heavy will cause serious consequences. Therefore, it is of vital importance to strengthen the management of safety, prevent accidents, ensure the physical and mental safety of patients during treatment, and avoid the occurrence of medical-origin diseases. Our practices are described below.
What are the most commonly used Six Sigma management tools for quality management?Commonly used Six Sigma management tools are as follows:
1, FMEA and FTA analysis
Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA) are in the reliability of the engineering has been widely used in the analysis techniques, foreign countries have been successfully applied to these techniques to solve a variety of quality problems. In the ISO 9004:2000 version of the standard, FMEA and FTA analysis has been used as a method of risk assessment for design and development, as well as product and process validation and change.
China is basically only FMEA and FTA technology applied to the reliability of design analysis, according to foreign literature and the practice of some of China's enterprises and technicians, FMEA and FTA can be applied to the process (process) analysis and analysis of quality issues. Quality is a concept with a wide connotation, and reliability is one of the aspects.
Through FMEA and FTA analysis, various potential quality problems and failure modes and their causes (including design defects, process problems, environmental factors, aging, wear and processing errors, etc.) affecting product quality and reliability are identified, and corrective measures of design and process are taken to improve the quality of the product and its resistance to various kinds of interference. According to the literature, a world-class automotive company achieves about 50% of its quality improvements through FMEA and FTA/ETA.
2, with POKA-YOKE
POKA-YOKE means "error-proof system". Japan's quality management experts, the famous Toyota Production System established by Mr. Shiso Shingo (Shingo Shingo) based on his long experience in the field of quality improvement, the first POKA-YOKE concept, and its development into a tool used to obtain zero defects, and ultimately exempted from quality inspection.
The basic concept of POKA-YOKE is as follows:
① Never allow even the slightest defective product, in order to become a world-class enterprise, not only in the concept, but also in practice, must achieve "0" defects.
② The production site is a complex environment, every day, every event may occur, errors lead to defects, defects lead to customer dissatisfaction and waste of resources.
③ We can not eliminate the error, but must be found in time and immediately corrected to prevent the error form defects.
3, SOW
Statement of Work (Statement Of Work, abbreviated as SOW) is one of the annexes to the contract, with the same legal effect as the body of the contract. The statement of work specifies in detail the work that both parties to the contract should be completed during the contract period, such as program demonstration, design, analysis, testing, quality control, reliability, maintainability, safeguard, standardization, measurement and guarantee, etc.; should be provided to the other side of the ad hoc, such as the interface control files, hardware, computer software, technical reports, drawings, information, and when to carry out what kind of review, etc., so the statement of work in the form of a contractual file Therefore, the statement of work in the form of a contractual file to further clarify the requirements of the customer and the contractor to achieve the customer requirements must be carried out, it makes the product management and quality assurance is based on the legal basis, become a contract party A (the customer) to party B (the contractor) to carry out quality control of a powerful tool. The detailed requirements of the statement of work can be found in GJB 2742-96. The content of the statement of work is an important input to the quality function.
4, WBS
Work Breakdown Structure (Work Breakdown Structures, abbreviated as WBS) is the weapons and equipment projects in the development and production process should be completed in the work from top to bottom level by level decomposition of a hierarchical system. The hierarchical system to develop and produce products as the center, by the product (hard and soft) project, service project and data project grouped into the WBS is formed through the work of systems engineering, it shows and determines the work of the weaponry project, and represents the relationship between the work and their relationship with the final product, fully embodies the system's holistic, orderly (hierarchical) and relevance. GJB2116-94 gives the typical development process of WBS and the basic requirements for its compilation, and provides the outline WBS for seven types of weapon systems in the appendix.
Applying the hierarchy of WBS in the work of quality function unfolding and system design, etc., and referring to the outline WBS given by GJB2116-94, will greatly facilitate the product's development.
5, parallel engineering
Concurrent Engineering (Concurrent Engineering) is for the product and its related processes (including manufacturing and security processes) for the parallel design of a systematic and integrated approach, which requires the developer from the outset to consider the entire product life cycle (from the formation of the concept of the product to the disposal of the end of the product) all the elements, including quality, cost, schedule and customer service. This includes quality, cost, schedule, and customer needs. Parallel engineering requires that special attention be paid to source design, and that at the beginning of the design phase, an attempt be made to synthesize all the information needed for product development, bringing together the experience and wisdom of experts from many disciplines.
The principles and guidelines of parallel engineering must be implemented in robust design, especially in quality function development and system design.
