Six Sigma Project: GE Healthcare’s MRI Machine Defect Reduction

Affiliation: University of Mumbai
Date: 19th October 2024

Executive Summary
This case study examines GE Healthcare's implementation of Six Sigma to reduce defects in its MRI machines. It highlights the process of identifying quality issues, implementing solutions, and achieving improved patient safety and reduced costs.

Introduction
Problem Statement
GE Healthcare faced significant quality issues with its MRI machines, leading to defects that could compromise patient safety. This case study explores how the company utilized Six Sigma to address these challenges.

Objectives

· To analyze the Six Sigma project undertaken by GE Healthcare.

· To evaluate the impact of Six Sigma on product quality and patient safety.

· To identify lessons learned for future quality improvement initiatives.

Methodology
The case study employs qualitative and quantitative methods, including interviews with project team members and analysis of defect reduction data over the project timeline.

Case Analysis
Key Facts

· Project Launch: The Six Sigma project commenced in 2005, targeting defect reduction in MRI machines.

· Defect Rate: Initial defect rates were approximately 15% for MRI machines.

Problem
The high defect rate of MRI machines was affecting patient safety and increasing operational costs.

Alternative Solutions Considered

1. Enhanced Quality Control Measures: Implement stricter quality checks during the manufacturing process.

2. Supplier Quality Assurance: Work closely with suppliers to ensure component quality.

3. Customer Feedback Loop: Establish a robust feedback mechanism to capture user experiences and identify areas for improvement.

Chosen Solution
GE Healthcare chose to implement a Six Sigma project focused on data analysis and process improvement to reduce defects.

Findings and Discussion
The Six Sigma initiative resulted in a reduction of defect rates from 15% to under 2%, significantly improving patient safety and lowering costs associated with recalls and repairs.

The project highlighted the importance of data-driven decision-making and cross-functional collaboration in quality management. GE Healthcare also established ongoing training programs for employees to maintain a culture of quality improvement.

Conclusion
GE Healthcare's Six Sigma project exemplifies the power of systematic quality management practices in healthcare. The project not only improved product quality but also reinforced the importance of patient safety. Future research should focus on developing standardized protocols for Six Sigma implementation in healthcare settings.
