What is the 8D report? The 8D report is a set of systematic analytical solutions and ideas for the problems that have occurred. It does not provide solutions or approaches to the problems. 8D mainly includes eight steps to deal with the problem: D1: the purpose of the group: set up a group, the team members have the knowledge of the process / product, the time allocated and granted the authority, at the same time should have the required technical quality to solve the problem and implement corrective measures. The team must have a guide and a team leader. Key Points: Membership, process and product knowledge; Goals; Division of labor; Procedures; Group Building D2: Problem Description Purpose: Quantitative terms detailing internal and external customer complaints related to the problem, such as what, where, time, degree, frequency, etc. Methods: Quality Risk Assessment, FMEA Analysis Key Points: Collect and organize all relevant data to illustrate the problem; Problem Statement is the summary of particularly useful data for the problem described; Audit existing numbers According to the problem, identify the problem, determine the scope; subdivide the problem into complex problems into a single problem; problem definition, to find a consistent explanation with the customer identified problem, "what happened what went wrong" and the reason is unknown risk level. D3: Implementing and validating Interim Measures Objective: To ensure that problems are isolated from internal and external customers before permanent corrective actions are implemented. Methods: FMEA, DOE, PPM Key Points: Evaluating Emergency Response Measures; Identifying and Selecting the Best "Temporary Suppression Measures"; Decision Making; Implementing and Recording; Verifying (DOE, PPM Analysis, Control Charts, etc.) D4: Identifying and Validating the Fundamental Reasons Purpose: Using Statistics The tool lists all potential causes that can be used to explain the cause of the problem, isolates the set of events or circumstances or causes mentioned in the problem description from each other, and identifies the root cause of the problem. METHODS: The key points of FMEA, PPM, DOE, control chart and 5W1H method were: to evaluate each cause in the list of possible causes; to exclude the cause; to verify; to select and verify the purpose of permanent corrective action; to test the program before production and to review the program to determine whether the corrective action selected can solve the problem. Household problems will have no adverse effects on other processes. METHODS: The key points of FMEA were: re-examination of team membership; decision-making, selection of best practices; re-evaluation of interim measures, such as necessary re-selection; verification; management commitment to implement permanent corrective measures; control plan D6: implementation of permanent corrective measures purpose: formulation of a plan for implementing permanent measures and determination of process control methods And included in the document to ensure the elimination of root causes. The long-term effect should be monitored when applying this measure in production. METHODS: Key points of error prevention and statistical control: re-examining the team members; implementing permanent corrective measures and abolishing temporary measures; confirming that the fault has been eliminated by measuring the fault; modifying D7 of control plan and process documents; preventing recurrence purposes: modifying the existing management system, operating system, work practices, design and Implementation Procedures to prevent this problem from recurring with all similar problems. Key Points: Selection of preventive measures; Validation of effectiveness; Decision-making; Organization, personnel, equipment, environment, materials, documents to redefine D8: Group Congratulations Purpose: Recognize the group's collective efforts, summarize and congratulate the group on its work. Key Points: Selectively retain important documents; read the group's work, the experience will be documented; understand the group's collective strength to solve the problem, and the contribution to solve the problem; the necessary material and spiritual incentives. For the above 8D steps, combined with my experience in the PCB factory, summed up the main difficulties in responding to the 8D report: 1. Too many quality problems (regardless of the company's internal quality problems, single customer complaints, may have an average of more than 2 orders per day), if each of the 8D steps are processed, time-consuming, labor-intensive, the various positions of the people. Can't spare oneself to deal with more than 8 D reports every day, so for the quality department frequently issued 8 D reports can only deal with the offset, the reply reports are on paper, not in line with the facts, to analyze and solve the problem can not play any substantive role. 2. Question description is not clear. After receiving complaints from customers, the Quality Department simply relayed the customer's problems, and did not further inquire the data related to the problems. It used the data to describe the problems more clearly, so as to help other people accurately judge the problems. 3. the process or production department did not analyze the problem thoroughly, and did not find the root cause. For example, when a customer complains that the hole has not been drilled, the production department checks the tools and data records and finds out that the reason is the broken bit, then the improvement measure is to change the bit. It seems that the reason and improvement measures have been found, but the actual problem is only solved at the moment, there is no preventive effect on the subsequent recurrence, maybe soon there will be a second, third occurrence. 4. The response improvement measures are too abstract to be translated into concrete action plans without quantitative indicators. For example, customer complaints about appearance problems, the final inspection department in the review of the improvement measures is to enhance the quality of employees, improve attention... How to enhance? How to improve? People still don't know how to do it, and such improvement measures are useless. For the above difficulties, we can improve from the following aspects: 1.
