Question

Instructions
Cignet Plastics Corporation is a contract plastics die-casting house serving a wide range of clients. Over the years, Cignet has been a favored supplier of precision die castings for a major producer of model airplane kits. In recent days, the defect rate of these parts has increased. (Acceptance is based on a visual inspection of the parts for appearance.) After a thorough audit of the process, Quality Assurance has concluded that there has been no change to the process. It claims that the increase in defects must be a variation that is related to some assignable cause. The president of Cignet Plastics does not have a clue as to what that means, and he has called you in for an explanation.

What approach would you use to get the operation back to normal? You will definitely want to explain management’s role in tool deployment.

Answer 2

To address the increase in defects in the die-casting process at Cignet Plastics Corporation, I would recommend implementing a systematic problem-solving approach such as the DMAIC (Define, Measure, Analyze, Improve, Control) methodology from Six Sigma. This approach focuses on identifying and eliminating the root causes of variations and defects in a process.

1. Define: The first step is to define the problem clearly and establish specific goals. In this case, the problem is the increase in defects in the die-casting process for model airplane kits. The goal is to reduce the defect rate and bring it back to the acceptable level.

2. Measure: In this step, the current defect rate needs to be measured accurately and consistently. Data should be collected on the number of defects, the frequency of their occurrence, and any other relevant process parameters. This will provide a baseline for evaluating the effectiveness of improvement efforts.

3. Analyze: The next step is to analyze the data to identify potential causes of the increased defect rate. Statistical tools, such as Pareto charts, cause-and-effect diagrams, and process capability analysis, can be used to identify the most significant factors contributing to the defects. It is important to involve cross-functional teams and gather input from operators, engineers, and quality assurance personnel during this analysis.

4. Improve: Once the root causes of the defects are identified, improvements can be implemented. This may involve modifying process parameters, adjusting machine settings, providing additional training to operators, or improving maintenance practices. The focus should be on addressing the specific causes identified during the analysis phase.

5. Control: To sustain the improvements and prevent recurrence of defects, control measures need to be implemented. This includes establishing monitoring systems, setting up standard operating procedures, conducting regular audits, and providing ongoing training to ensure that the process remains stable and within acceptable limits.

In terms of management's role in tool deployment, it is essential for the president and other leaders at Cignet Plastics to provide support and resources for the problem-solving initiative. They should foster a culture of continuous improvement and empower employees to actively participate in problem-solving activities. Management should also ensure that proper training is provided to employees on the use of problem-solving tools and techniques.

Furthermore, management should encourage collaboration between different departments and foster open communication channels. This will help facilitate the sharing of knowledge and ideas, leading to more effective problem-solving and improvement efforts. Regular monitoring and review of progress should be conducted to ensure that the implemented solutions are producing the desired results.

Overall, a systematic problem-solving approach like DMAIC, supported by effective management, can help Cignet Plastics identify and address the assignable causes of the increased defect rate, leading to improved quality and customer satisfaction.
