Ford Motor Company has built and sold vehicles for more than 120 years. It employs approximately 177,000 people across the globe. It operates manufacturing plants, assembly facilities, and engineering centers across multiple continents. At that scale, quality is not an aspiration. It is an operational requirement that must be built into every process, every shift, and every role.
Ford achieves this through a structured approach. It combines the Ford Production System with the Ford Quality Operating System. And it places certified Six Sigma practitioners at the center of its manufacturing improvement strategy.

How does Ford Motor Company use Six Sigma?
Ford Motor Company embeds Six Sigma directly into its manufacturing operations through the Ford Production System (FPS) and the Ford Quality Operating System (QOS). Ford employs Six Sigma Black Belts, Green Belts, and Master Black Belts across its North American manufacturing plants. These practitioners use DMAIC to improve quality metrics including initial quality scores, warranty rates, and customer satisfaction. Ford also uses DFSS (Design for Six Sigma) for new product development through its DCOV process.
In 2023, Ford achieved a 10% improvement in initial quality and tied management incentives directly to quality performance metrics.

Ford at Scale: Why Quality Requires a System
Ford is a global company based in Dearborn, Michigan. It builds vehicles across three customer-focused segments: Ford Blue for iconic gas and hybrid vehicles, Ford Model e for electric vehicles, and Ford Pro for commercial customers.
Ford develops, engineers, manufactures, and supports vehicles across all these segments. Quality defects in any one of them affect warranty costs, customer satisfaction scores, and the company’s financial results. Ford’s 2024 Integrated Sustainability and Financial Report confirms that vehicle and product safety is a material topic. It appears alongside human capital management and climate change as a priority area requiring structured, documented management.
Ford employs approximately 177,000 people worldwide. Managing quality consistently across that workforce and the supplier base it depends on requires a system. Ford built that system around two frameworks: the Ford Production System and the Ford Quality Operating System.

The Ford Production System: Where Lean Meets Six Sigma
The Ford Production System (FPS) is Ford’s core manufacturing operating framework. Ford’s official career documentation describes it as the system into which Lean and Six Sigma methodologies are embedded. Ford’s Lean and Six Sigma Team Managers are specifically tasked with embedding the FPS into operations at every plant.
Ford’s official job posting for its Lean and Six Sigma Team Manager role states the following responsibilities directly:
- Implement and lead Ford North America’s Lean and Six Sigma strategy in manufacturing plants
- Instruct on Ford Production System Standards and Lean Principles including Kaizen, 5S, Value Stream Mapping, Visual Management, and 8 Waste elimination
- Support the Ford Production System at manufacturing plants through mentoring and training
- Oversee gap closure plans for Lean Maturity Model in manufacturing plants
The FPS is not a passive framework. Ford requires its Lean and Six Sigma managers to actively assess each plant against a Lean Maturity Model. Plants that fall short receive a documented gap closure plan. Managers then drive those plants toward the required standard.
This structure ensures that Lean principles operate consistently across Ford’s North American manufacturing footprint. Kaizen events eliminate waste. Value Stream Mapping makes flow visible. 5S creates visual standards. And Six Sigma provides the statistical tools to reduce variation within those stabilized processes.
The Ford Quality Operating System
Ford operates a dedicated Ford Quality Operating System (QOS). Ford’s official Six Sigma Black Belt job postings list “understanding of the Ford Quality Operating System (QOS)” as a required qualification.
The QOS is the structured mechanism through which Ford manages quality performance. It integrates quality metrics, process standards, and continuous improvement activities into a single operating system. Six Sigma practitioners within Ford must understand and operate within this system.
Ford’s Vehicle Hardware Engineering (VHE) team applies this system to product development. Its official Six Sigma team job posting describes the following responsibilities:
- Lead and support current model production and design problem-solving teams using the DMAIC process to improve quality metrics including QNPS, R/1000, Warranty, and CPU
- Lead and support new technology and product design teams using the DCOV/DFSS process for failure mode avoidance and robust design methods
- Provide statistical and problem-solving support across the Vehicle Hardware Engineering organization
This confirms that Ford applies Six Sigma in two distinct modes. DMAIC improves existing production processes where quality problems have already emerged. DCOV (Define, Characterize, Optimize, Verify), Ford’s implementation of Design for Six Sigma, prevents quality problems from entering new products before they reach production.

How Ford Deploys Six Sigma Practitioners
Ford does not treat Six Sigma as a peripheral training program. It builds certified Six Sigma practitioners into the operating structure of its manufacturing facilities.
Ford’s career documentation confirms that it actively employs:
- Six Sigma Black Belts in supply chain and manufacturing roles across North American plants
- Green Belts whom Black Belts mentor and guide through DMAIC projects
- Lean and Six Sigma Team Managers (evolved from Master Black Belt roles) who lead the entire Lean and Six Sigma strategy for manufacturing regions
Ford’s official description of its Lean and Six Sigma Team Manager role captures this evolution precisely. Ford states: “We’re evolving our Master Black Belt roles into Lean and Six Sigma Team Managers. These skilled professionals will now integrate Lean methodologies as a core aspect of their responsibilities, alongside their expertise in Six Sigma.”
This evolution reflects a deliberate strategic decision. Ford recognized that pure statistical expertise — Six Sigma alone — was not sufficient. Its manufacturing operations needed practitioners who could simultaneously apply Lean waste elimination and Six Sigma variation reduction. The Lean and Six Sigma Team Manager role combines both.
These managers operate across Ford’s manufacturing facilities. They teach Black Belt and Green Belt classes on site. They mentor plant leadership directly. They liaise between business units to share knowledge and best practices across the organization.
Six Sigma Metrics Ford Tracks
Ford measures the results of its quality efforts through specific, named metrics. Ford’s official VHE Six Sigma team job documentation names four quality metrics that DMAIC projects must improve:
QNPS (Quality Net Promoter Score): Measures customer satisfaction with vehicle quality. Higher scores indicate that customers actively recommend Ford vehicles based on quality experience.
R/1000 (Repairs per 1,000 vehicles): Tracks how many vehicles require repair within a defined period after sale. This is a direct, quantifiable measure of defect rate at the vehicle level.
Warranty: Tracks the cost and frequency of warranty claims. Warranty costs are a direct financial measure of quality failures that escaped the manufacturing process.
CPU (Cost Per Unit): Measures the direct quality-related cost embedded in each vehicle produced. Lower CPU indicates fewer defects, less rework, and lower scrap rates.
DMAIC projects within Ford target improvements in each of these metrics. A project that reduces R/1000 by a measurable amount has a direct, quantifiable financial impact. Ford’s management team reviews these metrics as part of its regular operating reviews.
Ford’s 2023 Quality Results
Ford’s Q4 2023 earnings call transcript provides verified evidence of Ford’s quality performance. Ford reported a 10% improvement in initial quality during 2023. This is a publicly disclosed, verifiable figure confirmed in Ford’s own investor earnings materials.
The same earnings call confirmed two additional quality commitments. First, Ford tied management incentives directly to quality metrics. Compensation outcomes for Ford’s leadership team now depend in part on quality performance. This is a structural commitment that elevates quality from a manufacturing concern to a company-wide priority at the executive level.
Second, Ford made a significant financial decision that reflects its commitment to quality. It accepted a $1 billion EBIT trade-off on the Super Duty truck launch. Ford chose to take a substantial financial hit rather than launch a vehicle that did not meet its quality standards. That decision communicates the seriousness with which Ford’s leadership treats quality performance.
These disclosures are Ford’s own words from its own investor communications. They confirm that Six Sigma quality improvement is not a background program at Ford. It is a priority visible at the CEO and CFO level.
Ford Production System and Carbon Reduction
Ford’s 2024 Integrated Sustainability and Financial Report confirms that the Ford Production System extends beyond manufacturing quality into environmental performance. Ford reduced global Scope 1 and Scope 2 greenhouse gas emissions by 47% between 2017 and 2023. The U.S. Department of Energy acknowledged Ford for achieving deep and sustained energy and greenhouse gas savings at 31 locations in the United States, including all of Ford’s manufacturing facilities.
The Ford Production System drives this performance. Energy forecasts and reduction targets are integrated into the FPS through Ford’s Energy Management Operating System (EMOS). Ford establishes annual energy forecasts and targets for every global manufacturing facility through this system.
This demonstrates that the FPS applies continuous improvement discipline not only to quality but also to resource consumption. The same system that uses Six Sigma to reduce defects uses structured monitoring and target-setting to reduce energy waste. The improvement philosophy is consistent across both domains.
What Ford’s Approach Teaches Practitioners
Ford’s documented approach to quality improvement contains clear lessons for any organization deploying Six Sigma.
Integration beats isolation. Ford does not run Six Sigma separately from its production system. It embeds Six Sigma within the Ford Production System, ensuring that statistical tools and lean waste elimination work together inside the same operating framework.
Roles must evolve. Ford’s decision to evolve Master Black Belt roles into Lean and Six Sigma Team Managers reflects a recognition that quality problems require both statistical depth and operational breadth. Practitioners who only know statistics and practitioners who only know Lean are both limited. Ford builds roles that require both.
Metrics must be tied to accountability. Ford tied management incentives directly to quality metrics. This structural commitment ensures that quality performance is visible to every level of the organization, from the plant floor to the CEO.
Prevention matters as much as correction. Ford applies DMAIC for existing processes and DCOV/DFSS for new product development. Catching a failure mode before it enters production is more effective than correcting it after it reaches customers.
