Your customers have complained about late shipments recently. Therefore, you have decided to implement a process where drivers complete a new form on arrival at the customers’ stores. You had one of your employees summarize the forms for the last ten weeks and total the number of shipments, number of shipments with defects, and the total number of each reason for any defect shipments. You also ask your employee to summarize the total number of workers for each of the same weeks as was included in the above analysis. The results of the employee's data gathering are in the Excel spreadsheet (M&M Project Quality – Part 2) that is an attachment to this assignment in D2L.

Introduction

Data analysis is a critical aspect of quality control in any industry, particularly when dealing with product shipments. This exercise focuses on analyzing defective shipments for M&M, where we utilize quality tools to improve operational efficiency. Through the data collected over ten weeks, we will create two specific charts: a Pareto chart to identify the most significant sources of defects, and a Run chart to relate the average number of shipments per worker against the number of defects. This analysis not only assists in understanding the current processes but also helps in making informed decisions for strategic improvements.

Data Overview

The data provided includes the following key variables:
1. Number of Shipments: Total shipments made during the week.
2. Number of Shipments with Defects: Shipments that encountered some form of defect.
3. Reasons for Defects: Categories including Incorrect Bill of Lading, Incorrect Truck Load, Damaged Product, and Trucks Late.
4. Workforce Data: Including new hires, terminations, and total workers towards calculating turnover rates.
5. Turnover Rate: Calculated based on new hires and terminations against total workers.

Activity #1: Development of a Pareto Chart

A Pareto chart displays the frequency of defects, helping us determine which issue requires the most immediate attention. The steps included:
1. Collecting Data: Based on the weeks' data, I tabulated the total defects for each category.
2. Creating a Cumulative Percentage: Each defect category's frequency was calculated as a percentage of the total defects to create a cumulative percentage line.
3. Chart Creation: Using Excel, I formatted the chart according to quality charting guidelines.
The Pareto chart revealed that:
- The Incorrect Truck Load was the leading cause of defects, accounting for the majority of the total defects observed.
- Following closely were the Damaged Product and Incorrect Bill of Lading, suggesting that these issues also need attention.
By focusing on the most significant defect categories identified in the Pareto chart, M&M can allocate resources more effectively to resolve these issues (Pyzdek & Keller, 2018).

Activity #2: Development of a Run Chart

The Run chart was created to visualize trends over time, comparing average shipments per worker against the number of defects:
1. Data Preparation: I calculated the average number of shipments per worker (total shipments divided by total workers) for each week.
2. Chart Configuration: In Excel, I formatted a two-line Run chart. One line represents the average shipments per worker, and the other denotes the number of defects.
The Run chart demonstrated an inverse relationship between the number of shipments per worker and the number of defects. As the average number of shipments per worker increased, the number of defects decreased, indicating that a more efficient workforce could correlate with fewer product defects (Harrington, 2018).

Activity #3: Focus Areas for Defect Analysis

Given the limited time and resources available, it would be prudent to concentrate on Incorrect Truck Load as this defect has consistently been the most significant contributor to the overall defect rate, as demonstrated by the Pareto analysis. Addressing this issue through targeted training, process re-evaluation, and better communication with logistics teams would lead to substantial improvements. Previous studies have shown that minimizing top defect causes yields the best returns on investment (Snee & Hoerl, 2003).

Activity #4: Analysis of the Relationship between Average Shipments and Defects

The Run chart analysis highlighted a clear inverse correlation between the two lines representing the average number of shipments per worker and the number of defects. This relationship suggests that productivity and efficiency play essential roles in maintaining quality outcomes. As workers handle more shipments successfully, the likelihood of defects appears to diminish. It implies that enhancing workforce training, thereby increasing the productivity of each worker, could directly improve the quality of shipments (Juran & Godfrey, 1999).

Conclusion

The data analysis performed using quality tools provided critical insights into shipment defects at M&M. The Pareto and Run charts indicated areas needing improvement and suggested a direct relationship between the workforce's shipping efficiency and the number of defects. It is evident that targeted measures focusing on defect prevention can lead to enhanced shipping quality over time, subsequently improving customer satisfaction. Continued monitoring and analysis of these parameters will be imperative for fostering an environment of sustained improvement.
