Six Sigma Quality Model at General Electric
This paper examines the implementation of the Six Sigma quality improvement model at General Electric (GE), a Connecticut-based conglomerate founded in 1878. It introduces the Six Sigma methodology — originally developed by Motorola — and outlines its two primary implementation frameworks: DMAIC (Define, Measure, Analyze, Improve, Control) and DMADV (Define, Measure, Analyze, Design, Verify). The paper traces GE's adoption of Six Sigma beginning in the 1980s, describing how the company adapted the model to its unique organizational needs through six core quality principles and Work-Out learning programs. Financial evidence, including operating revenue increases exceeding $300 million reported in 1997, is cited to demonstrate the measurable benefits GE achieved through sustained commitment to the methodology.

What makes this paper effective
- It grounds abstract methodology in a concrete, well-known corporate case study, making the Six Sigma framework accessible and credible through real-world application.
- Direct quotations from General Electric's official communications and annual reports lend authority to the analysis without overstating the paper's own claims.
- The paper consistently reinforces the key nuance that Six Sigma must be customized to each organization — avoiding the trap of presenting it as a universal solution.
Key academic technique demonstrated
The paper uses a definition-then-application structure: it first establishes a theoretical framework (Six Sigma definitions, DMAIC vs. DMADV) before moving to the corporate case study. This technique allows readers to evaluate the implementation against a clearly stated standard, and it is well-suited to business and management writing at the undergraduate level.
Structure breakdown
The paper is organized into five clearly numbered sections. The introduction contextualizes the business challenges driving quality initiatives. The second section profiles GE and its conglomerate industry. The third section defines Six Sigma and its two core methodologies. The fourth section — the analytical heart of the paper — details GE's specific implementation, six quality principles, and financial outcomes. The conclusion synthesizes key findings and reiterates the necessity of customizing the model to organizational needs.
Introduction
The contemporary business community faces numerous challenges, the most significant of which relate to the changing needs and behaviors of customers, the increasing demands of staff members, and the strategic approaches implemented by competitors. Organizations strive to find ways to counter the external forces that jeopardize their success in the marketplace, and a primary goal in this effort has been to significantly improve the quality of operational processes as well as the quality of the final products and services offered to customers.
A primary method of achieving these goals has revolved around the implementation of the Six Sigma model. It strives to create a business environment characterized by high quality and an absence of error. The methodology has been analyzed and refined over the years to offer organizations better chances of success. It was first developed and implemented by Motorola, but has since gained widespread recognition. It is based on the use of numerous tools, and the two most significant implementation techniques are Six Sigma DMAIC and Six Sigma DMADV.
A relevant example of an organization that has successfully implemented these concepts is Connecticut-based General Electric. The company was established in 1878 and operates in the conglomerate industry. General Electric first implemented the Six Sigma model in the 1980s, grounding it in the principles of the learning organization. Over time, GE came to enjoy the benefits of the methodology, most notably in the form of significantly higher profits.
General Electric and Its Industry
General Electric was established in New Jersey in 1878 and has since proved its worth by driving numerous advancements that have changed modern life. The company is currently headquartered in Fairfield, Connecticut, and employs an estimated 327,000 individuals. At the end of fiscal year 2007, the company registered revenues of $172.738 billion, of which $22.208 billion represented net income (Website of General Electric, 2008). This followed a continuously ascending trend.
The company operates in the conglomerate industry, producing primarily aircraft and aircraft-related products — both hardware and software. It also produces technologies to support the development of the manufacturing, medical, and transportation sectors. A defining feature of the conglomerate industry is that it is composed of large multinational organizations that conduct various types of operations, sometimes entirely unrelated to one another. In other words, a company in the conglomerate sector may operate across multiple fields, which is why it cannot be simply classified within a single industry type. It is therefore accurate to say that General Electric simultaneously operates in the manufacturing, medical, transportation, and technology industries.
Regarding the conglomerate industry and its adoption of Six Sigma, recent trends indicate an increased focus on quality improvement. The Six Sigma model has been implemented at various organizational levels and has produced successful outcomes. One important challenge, however, remains the task of implementing the model as an integrated system across all operations managed by a conglomerate.
The Six Sigma Methodology
The Six Sigma model emerged from the need to continuously improve the quality of operations and outcomes within an economic entity. Definitions of the concept have varied in form over the years, but tend to center on the same core ideas. Thomas Pyzdek (2003), for instance, defines the method as a "rigorous, focused and highly effective implementation of proven quality principles and techniques. Incorporating elements from the work of many quality pioneers, Six Sigma aims for virtually error-free business performance." The iSix Sigma website (2008), on the other hand, offers a more technical definition, describing it as a "disciplined, data-driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process — from manufacturing to transactional and from product to service."
The two most important methodologies for implementing Six Sigma are DMAIC and DMADV. The first acronym stands for Define–Measure–Analyze–Improve–Control, and the second stands for Define–Measure–Analyze–Design–Verify. The DMAIC methodology is used to improve the quality of existing systems that encounter difficulties and consequently require incremental improvement. The DMADV methodology is used to create new processes or products at Six Sigma quality levels.
Both DMAIC and DMADV quality improvement methodologies are implemented by Six Sigma Green Belts and Six Sigma Black Belts, and are verified and approved by Six Sigma Master Black Belts — the highest-level experts in the field (iSix Sigma website, 2008).
