D0: Emergency response to signs – The purpose of this step is to determine whether such a problem requires resolution using the 8D method. If the problem is too minor or not suitable for being resolved through 8D, such as issues related to price or funding, then this step serves as an emergency response when the problem occurs.

D0: Emergency response measures for signs; D1: Formation of the team; D2: Description of the problem; D3: Implementation and verification of temporary measures; D4: Identification and verification of the root cause; D5: Selection and verification of permanent corrective actions; D6: Implementation of permanent corrective actions; D7: Prevention of recurrence; D8: Team celebration

D0: Urgent response measures for signs. Purpose: It is mainly to determine whether such issues require resolution using the 8D method. If the issue is too minor or not suitable for being resolved through 8D, such as issues related to price or funding, this step serves as an urgent response when the problem occurs. Key points: Determine the type, scale, scope, etc. of the problem. Unlike D3, D0 is a response to the occurrence of a problem, whereas D3 is a temporary measure taken to address the issue with the product or service itself. D1: Formation of a team. Purpose: To establish a team whose members possess knowledge of processes/products, have the necessary time available, and have been granted the appropriate authority; they should also have the technical skills required to solve problems and implement corrective actions. The group must have a supervisor and a team leader. Key points: Membership, knowledge of processes and products ； Goal ； Division of labor ； Program ； Team Building D2: Problem Description Purpose: To detail the internal/external customer complaints related to this issue using quantitative terms, such as what happened, where, when, to what extent, and how frequently. ““What went wrong?” Method: Quality risk assessment, FMEA analysis. Key points: 1. Collect and organize all relevant data to explain the problem. 2. A problem description is a summary of data that is particularly useful for describing the issue at hand. 3. Review existing data to identify the problem and determine its scope. 4. Break down the problem by dividing complex issues into individual ones. 5. Define the problem by finding a description that matches what the customer has identified as the problem; in other words, “What went wrong?”, while the cause remains unknown, along with the risk level. D3: Implement and verify temporary measures. Purpose: To isolate the issue from internal and external customers until permanent corrective actions are taken. (Originally the only optional step, but it is now required in all cases.) Methods: FMEA, DOE, PPM. Key points: 1. Evaluate emergency response measures. 2. Identify and select the best “temporary mitigation measures.” 3. Make decisions. 4. Implement these measures and keep records. 5. Verify (using DOE, PPM analysis, control charts, etc.). D4: Determine and verify the root cause. Purpose: Use statistical tools to list all potential causes that could explain the origin of the problem; isolate and test the various events, conditions, or factors mentioned in the problem description in order to identify the true root cause. Methods: FMEA, PPM, DOE, control charts, 5Why method. Key points: 1. Evaluate each cause listed as a possible reason. 2. Determine whether the cause can resolve the problem. 3. Verify. 4. Develop a control plan. 8D problem-solving approach: D5 – Select and verify permanent corrective actions. Purpose: Test the solution before production and review it to ensure that the chosen corrective actions can resolve the customer’s issue without having adverse effects on other processes. Methods: Key points of FMEA: 1. Re-examine the qualifications of team members. 2. Make a decision to select the best corrective action. 3. Reassess temporary measures and select new ones if necessary. 4. Verify the effectiveness of the actions taken. 5. Obtain management commitment to implement permanent corrective actions. 6. Control plan D6: Implementing permanent corrective actions. Purpose: To develop a plan for implementing permanent corrective actions, determine the methods for process control, and document them in order to ensure that the root cause is eliminated. When applying this measure in production, its long-term effects should be monitored. Methods: Error prevention, statistical control. Key points: 1. Reassess team members. 2. Implement permanent corrective actions and eliminate temporary ones. 3. Use the measurability of faults to confirm that they have been resolved. 4. Modify control plans and process documents. D7: Prevent recurrence. Purpose: Modify existing management systems, operating procedures, work practices, designs, and regulations to prevent this issue and all similar problems from occurring again. Key points: 1. Select preventive measures 2. Verify effectiveness 3. Make decisions 4. Redefine organization, personnel, equipment, environment, materials, and documents. D8: Group congratulations – Purpose: To acknowledge the group’s collective efforts, summarize the group’s work, and offer congratulations. Key points: 1. Selectively retain important documents. 2. Review group work and document the insights gained. 3. Understand the group’s collective strength in solving problems and its contribution to those solutions. 4. Provide necessary material and spiritual rewards.
