In order to improve the response speed and satisfaction of customer service, and strengthen the quality awareness of all staff, Wu Zehua, engineer of Lead Thermoelectric Quality Department, conducted 8D problem solving related training for everyone. In the meeting, Wu Gong introduced the specific content of 8D problem solving method in detail, and encouraged everyone to actively use this method in future work. When employees encounter unexpected problems such as customer complaints or production anomalies, learn to apply 8D problem solving method to deal with and solve problems more rationally and professionally.

The following is 8DThe specific content of the solution

D1 Set up a problem solving team: set up a leader-led team, including personnel from quality, technology, equipment, production and other related departments. Team members must be able to perform tasks such as adjusting machine parameters, changing production processes, or directing screening.

D2 Describe the problem: Use the 5W2H methodology to present a detailed situation to the team, that is, explain when and where the problem occurred, the specific situation, the severity, the current status, the emergency action taken, and show the relevant photos and evidence collected. Imagine yourself as an FBI agent, and the clearer you describe the evidence and details, the faster the team will solve the problem.

D3 Implement temporary countermeasures: If the root cause has not been identified, temporary measures can be taken to prevent the problem from worsening, such as conducting a comprehensive inspection, screening, switching from automated production to manual operations, or conducting inventory checks. Once a temporary response is determined, it should be implemented by team members immediately.

D4 Find the real cause of the problem: When looking for the root cause of the problem, do not blindly change the existing production state. The first thing to do is to observe, analyze and compare. You can use the fishbone chart to list all the conditions that may affect production, and check if any conditions have changed, such as changing fixtures, operators, suppliers, transporters, equipment repairs, process changes, etc. By comparing the test results of good and bad products, look for differences. Data such as size, weight, voltage value, voltage resistance can be key clues. Such an analysis helps to narrow down the scope and get closer to the core of the problem. When the analysis is complete, make a list of the most likely causes and test them one by one until you find the true root cause.

D5 Choose a permanent response: Once the root cause of the problem has been identified, a permanent response can be developed. There are many possible solutions, such as repairing or replacing the mold. At this point, the pros and cons of each option need to be evaluated, including the required funds, manpower, and durability of implementation. Finally, the optimal solution is selected, and it is confirmed that the solution does not cause other side effects.

D6 Implementation and validation of permanent countermeasures: Once the permanent countermeasures are ready, implementation can begin and the previous interim measures can be discontinued. Ensure that permanent countermeasures are effectively implemented and validated to ensure that the problem does not recur.

D7 prevent recurrence: Even if the same problem has not been found on other production lines, it should be improved simultaneously to prevent similar problems from happening again. At the same time, this failure event should be recorded in the FMEA (Failure Mode and Effect Analysis) of the product for future reference.

D8 Team motivation: Give recognition to team members who work hard to solve problems, so that they feel a sense of accomplishment in solving problems, and are willing to continue to actively respond to problems in the future.

The importance of successful implementation of the 8D method

In particular, the meeting noted that the successful implementation of the 8D method depends on the team spirit of cooperation and the attitude of employees to continuous improvement. In the face of problems, first of all, keep calm and quickly take emergency remedial measures to prevent further deterioration of the problem. Then, through systematic analysis and scientific methods, we can find the root cause and formulate effective countermeasures. In addition, the importance of preventing recurrence can not be underestimated: when we encounter a problem, in addition to solving the problem, we also think about how to prevent and ensure that such problems do not happen again, so as to continuously improve the quality of products and customer satisfaction.

Through this training, participants have mastered the core points of the 8D method and learned how to flexibly use this tool in practical work. It not only improves the efficiency of solving problems, but also strengthens the sense of responsibility and quality awareness of employees. We believe that we can apply what we learn, improve the company's quality management system, and provide customers with more quality products and services.
