Question

ABC manufacturing plant manufactures various metallic screws, nuts, plates and other industrial goods defects. There are 250 employees and 25% are relatively new. Training is imparted once in 2 years. On observing one product- metallic Hexagonal nuts of various sizes like 3/8, 3/4, 9/16 etc., they analyzed the Product's quality statistics for three weeks and gathered some data that shows the following. The data shows the following defects during the run of production for 3 weeks. Some defects were seen and measured like some were not properly polished, not properly shaped, not proper winding spirals, perforations in the screws, cracks, not finished well etc. The data is given in the table below. Jane, an excellent CEO wants to improve on the quality of this product. As Jane's Operations Manager, help Jane draw up conclusions to rectify the defects. The Rubric is posted below. ALL are to be done only on the same Excel file- one sheet or multiple sheets, through the following processing order of Answers 1 to 5:

Draw a Pareto Chart and identify the most priority defects to address beneath the graph. Why do you say so

Answer 1

By using a Pareto Chart to analyze defects in metallic hexagonal nuts, the most critical defects can be identified and prioritized for rectification. This targeted approach based on the Pareto principle allows for efficient and effective quality improvement, focusing resources on the most impactful issues.

Step-by-step explanation:

In response to improving product quality at ABC manufacturing plant, specifically for metallic hexagonal nuts, a Pareto Chart is an effective tool. This chart will help in identifying the most critical defects that should be addressed first. It is based on the Pareto principle, which suggests that approximately 80% of problems are caused by 20% of causes. By charting the defects and their frequencies, the chart will reveal which defects are most common.

If the Pareto Chart shows that a significant majority of defects are due to not being properly shaped, for instance, then this defect becomes a priority.

Addressing this issue may improve the quality of a large number of units. The reason for prioritizing defects with the highest frequency is to achieve the greatest overall quality improvement efficiently. Training could be focused on areas causing the most defects, and processes or machinery could be reviewed for enhancements.

Focused quality control protocols and continuous improvement programs can then be implemented specifically targeting these high-priority defects. This should lead to a noticeable improvement in the overall quality of the products manufactured.
