Dude, if it's not specific, I can only say the general method. Small problem: 1, to calm the customer's mood; 2. Understand the problem of production clarification (5W2H2R)3. Understand customer requirements; 4. Provide solutions and implement them after the customer agrees; 5, check the real cause of the problem, standardize the fundamental solution. This should be enough for little things. If it's a big event, you can report it in 8D. 8D report, also known as team-oriented problem solving method, 8D problem solving is a method used by Ford to solve problems, and it is also suitable for solving related problems when the process capability index is lower than its due value. It provides a set of logical problem solving methods, and also bridges the gap between statistical process control and actual quality improvement. Eight steps to solve problems in the catalogue, eight-step method, eight-step method, eight-step method, eight-step method, eight-step method, eight-step method, eight-step method, eight-step method, eight-step method was originally a classic quality problem analysis method used by Ford Company in the United States. During World War II, the US government took the lead in adopting a process similar to 8D-"Military Standard 1520", also known as "Corrective Action and Deployment System for Nonconforming Products". 1987, Ford motor company recorded the 8D method in writing for the first time, and named it "team-oriented problem solving" in one of its course manuals. At that time, Ford's power system department was at a loss because of some production problems that appeared repeatedly for many years, so its management asked Ford Group to provide guidance courses to help solve the problems. Eight-step method for solving problems 8D (eight disciplines) The original name of eight-step method for solving problems 8d is eight principles, which means eight fixed steps for solving problems. At first, it was a special necessary method for Ford to control and improve global quality, and later it has become a special requirement of QS9000/ISO TS 16949 and Ford. All parts manufactured by Ford must use 8D as a tool for quality improvement. At present, some enterprises are not Ford suppliers or auto industry partners, and they also like to use this convenient and effective method to solve quality problems and become fixed and standardized problem-solving steps. Subject 1. Form a team: composed of people related to the subject, usually cross-functional, explaining the division of labor or responsibilities and roles of team members. Discipline 2. Describe the problem: express the problem as quantitatively and clearly as possible, and solve the long-term problem instead of just the immediate problem. Subject three. Implement and confirm temporary countermeasures (containment problem): take immediate short-term measures to solve D2 to avoid the problem from expanding or worsening, including clearing inventory, shortening PM time and increasing manpower. Discipline 4. Find out the root cause: the real cause of D2 problem, and explain the application of analysis methods and tools (quality tools). Subject five. Select and confirm the corrective measures that have been formulated and verified: make improvement plans, list possible solutions, select and implement long-term countermeasures, verify the improvement measures, and eliminate the real causes of D4. Usually, the long-term improvement measures are explained step by step, and Gantt chart or quality method can be applied. Subject six. Correct the problem and confirm the effect: the result and validity verification after D5. Discipline 7. Prevention: Follow-up action plan to ensure that D4 problem will not happen again, such as personnel education and training, improving case sharing (fanout), standardizing operation, producing BKM, implementing FCN, sharing knowledge and experience, etc. Discipline 8. Congratulations to the team: If the problem has been improved after the above steps are completed, we will definitely improve the team's efforts and plan the future improvement direction. 8D Scope of Application This method is suitable for solving various simple or complex problems that may be encountered; The 8D method is to establish a system so that the whole team can enjoy the information and strive to achieve the goal. 8D itself does not provide a successful method or way to solve problems, but it is a very useful tool to solve problems. It is also suitable for solving related problems when the process capability index is lower than its due value; Provide solutions to customer complaints and major defects. 8D method is a method used by American Ford Company to solve product quality problems. Widely used by suppliers, it has now become the best and effective method to solve product quality problems widely used by international automobile industry (especially automobile parts manufacturers). The eight steps of 8D working method are eight basic principles or eight working steps to solve problems. However, there are nine steps in practical application: D0: symptom emergency response measures D 1: group establishment D2: problem explanation D3: implementation and verification of temporary measures D4: determination and verification of root causes D5: selection and verification of permanent corrective measures D6: implementation of permanent corrective measures D7: prevention of recurrence D8: group congratulations D0: symptom emergency response measures Purpose: mainly to see whether such problems need 8D. To solve the problem, if the problem is too small, or it is not suitable to solve the problem in 8D, such as price, capital, etc. This step is designed for emergency response when problems occur. Key points: judge the type, size, category and so on of the problem. Unlike D3, D0 is a response to the problem, while D3 is a temporary response to the product or service problem itself. D 1: The purpose of group establishment is to establish a group whose members have knowledge of process/product, have time to allocate and be granted authority, and have the technical quality needed to solve problems and implement corrective measures. A team must have a director and a team leader. Focus: membership, technology and product knowledge; Target; Division of labor; Procedures; Team Building D2: Problem Description Purpose: To specify the internal/external customer complaints related to this problem in a quantitative way, such as what, place, time, degree, frequency, etc. "What's wrong" method: quality risk assessment and FMEA analysis points: collect and sort out all relevant information and explain the problem; The problem description is a summary of the particularly useful data of the described problem; Review existing data, find problems and determine the scope; Subdivide the problem and divide the complex problem into a single problem; Definition of the problem, find a description consistent with the problem confirmed by the customer, "What happened to something", and the reason is unknown risk level. D3: Implementation and verification of temporary measures Purpose: To ensure that problems are isolated from internal and external customers before implementing permanent corrective measures. Methods: FMEA, DOE and PPM Key points: Evaluate emergency response measures; Find out and choose the best "temporary restriction measures"; Decision-making; Implementation, and make records; Verification (DOE, PPM analysis, control chart, etc. D4: Determine and verify the root cause Purpose: List all the potential causes that can be used to explain the cause of the problem with statistical tools, isolate and test a series of events or environments or causes that cause the deviation mentioned in the problem description, and determine the root cause of the problem. Methods: FMEA, PPM, DOE, control chart, 5why method key points: evaluate each cause in the list of possible causes; Whether the reason can eliminate the problem; Verification; Control Plan D5: Selection and Verification of Permanent Corrective Measures Purpose: To test and review the scheme before production to ensure that the selected corrective measures can solve the customer's problems and have no adverse effects on other processes. Methods: FMEA points: re-examine the team members; Make decisions and choose the best measures; Re-evaluate the temporary measures and re-select if necessary; Verification; The management promises to implement permanent corrective measures; Control Plan D6: Implementing Permanent Corrective Measures Purpose: To formulate a plan for implementing permanent measures, determine the process control methods and include them in the document, so as to ensure that the root causes are eliminated. When this measure is applied in production, the long-term effect should be monitored. Methods: The key points of error prevention and statistical control: re-check the team members; Implement permanent corrective measures and abolish temporary measures; Use the measurability of the fault to confirm that the fault has been eliminated; Modification of control plan and process document D7: Prevent recurrence Purpose: Modify the existing management system, operating system, work practice, design and procedures to prevent this problem from recurring with all similar problems. Key points: choose preventive measures; Verify effectiveness; Decision-making; Redefine the organization, personnel, equipment, environment, materials and documents D8: Congratulate the group Purpose: To recognize the group's collective efforts and summarize and congratulate its work. Key points: keep important documents selectively; Browse the work of the group and record the experience; Understand the collective strength of group to solve problems and its contribution to solving problems; Necessary material and spiritual rewards. The evaluation of 8D working method is 1. The advantage is to find an effective way to find the real cause, and to take targeted measures to eliminate the real cause and implement permanent corrective measures. It helps to explore the control system that allows the problem to escape. The study of escape point is helpful to improve the monitoring ability of control system when the problem reappears. The study of prevention mechanism helps the system to control the problem in the initial stage. 2. Disadvantages: The training fee is 8 days, which is difficult in itself. In addition to the 8D problem-solving process training, data mining training is also needed, as well as the required analysis tools (such as Pareto Diagram, Fishbone Diagram, Flowchart, etc.). ).[ 1]
