8D Case Exercise - Store Manager Wang's Wife Wants to Divorce D1:Improved topic selection and problem description Problem description: D2:Emergency Response & Goal Setting D3:Current Situation Analysis Current Situation Analysis,Data Collection (4W2H Management): Store Manager Wang's wife's family performance checklist: Wang's store manager's wife's family performance Plato: This can be seen from the diagram,Quarrels are the most。 D4:Preliminary cause analysis and verification;Formulate and implement temporary countermeasures to identify possible causes: Confirm the main cause—Elimination: Formulate and implement temporary countermeasures: D5:Detailed cause analysis and verification;Development and implementation of permanent countermeasures System diagram method: Decision evaluation: D6:Effect Confirmation Confirmation of the effect of countermeasures: 8D knowledge,You need to know that 9 steps 8D is the 8 basic principles of problem solving, or 8 working steps,But in practice, there are 9 steps: D0:Signs Emergency Response Measure D1:The group formed D2:Problem Note D3:Implement and validate Interim Measure D4:Identify and validate Root Cause D5:Select and validate permanent corrective action D6:Implement permanent corrective action D7:Prevent recurrence of D8:The group congratulated the 3 questions SQE on when it came to training suppliers on 8D reporting,It must be made clear to the supplier,As a supplier, when writing 8D reports,It is important to ensure that the following questions are answered clearly, accurately, and reasonably: D2 - What is the problem? D3~D6 - How to solve the problem? D7 - How to prevent the problem in the future 7 problems as SQE when reviewing the supplier's 8D report however,It is also important to ensure that the following questions are answered truthfully: 1.The knowledge of the part is fully demonstrated; 2. The root cause is fully identified and focused; 3. The missing point has been identified; 4. The corrective action that matches the root cause has been identified; 5. The validation of the corrective action plan has been determined; 6. The time plan for implementing the corrective action has been included; 7. There is evidence that the supplier will integrate the corrective action into the system。 Quality Tools The quality tools that may be used in the implementation of 8D are summarized below: Reliability/Design VerificationDV/Product & Process Qualification/Potential Failure Mode and Effects AnalysisFMEA/Control PlanCP/PPAP Documents/SPC/DOE/QC7 Tools D0:Indication of emergency response measures Purpose:The main thing is to see if such problems need to be solved with 8D,If the problem is too small,or problems that are not suitable for 8D,For example, price,Funding and so on,This step is an emergency response to a problem as it occurs。 Key takeaways::Determine the type of problem、size、categories and so on。Unlike D3,D0 is the reaction to the occurrence of the problem,D3, on the other hand, is a temporary response to the problem with the product or service itself。 tool:Trend Chart/Permutation Chart/Paynter Chart/ERA(Emergency response measures) D1:The purpose of the formation of the group:Form a group,The team members have knowledge of the process/product,There was rationed time and permission was granted,At the same time, they should have the required technical quality to solve problems and implement corrective measures。The group must have a mentor and group leader。 Key takeaways::Membership,Craftsmanship、Knowledge of the product;target ;Division ;procedure ;Group building 。 tool:Action Plan、time management、Team Charter、Gantt Chart(Pilot) D2:Description of the problem Purpose:Detail internal/external customer complaints related to the issue in quantified terms,Such as what、place、Time、extent、frequency, etc。 "What went wrong with something" Key takeaways:Collect and organize all relevant data to illustrate the problem;A problem description is a summary of particularly useful data for the problem described;Review existing data,Identify the problem、Determine the scope;Segment the problem,Break down complex problems into individual issues;Problem definition,Find a description that matches the customer's identified issue,"Something went wrong",The reason for this is unknown risk level。 tool:Quality risk assessment,FMEA analysis,5W2H(What/Why/When/Where/Who/How/Howmany)、Line chart、histogram、Arrangement Figure D3:Implement and validate interim measures Read More …
